Saphir – Watch Magazine for Women

Chanel J12 Tourbillon Haute JoillerieNot too long ago I wrote about how women just don’t get the attention that men do from the watch industry. Well here’s a little update.

This week at work we received a copy of Saphir: The luxury Magazine of Fine Timepieces, Jewelry and Fashion. It’s a magazine from the people at WatchTime and as the editor Amy Bernstein describes it, “saphir is a magazine committed to women and their fine timepieces.” Here are some excerpts:

Because women today lead such active lifestyles many watch brands are making strides to give ladies watches that are as functional as they are stylish. In this issue, you’ll find stories on popular new features like the GMT function for that regularly traveling woman and the chronograph for the woman with that sporty edge.

Saphir: If a woman can’t affore – or prefers not to own – many watches, which one would you reocmmend to her?
Wempe:
The answer is very simple. She should choose the one she needs most often and the one that goes best with the greatest number of different outfits.

Saphir: When should a woman opt for a mechanical watch, and when should she choose a quartz one?
Wempe:
That depends on her interests. If she isn’t at all interested in technology or mechanisms, she’d no doubt be happier with a quartz watch. Some women go out and buy a Rolex and are afterwards surprised to discover that they need to wear it every day in order to keep its self-winding movement running. On the other hand, more women are taking an interest in mechanical functions these days and derive real pleasure from them. Personally, I’m fascinated by perfectly functioning mechanical watch movements.

All in all, I found the magazine to be a little bit disparaging. It’s just as much (or more) about the fashion of the watch, even when they are talking about a highly complicated mechanical timepiece, despite what they say. You men however, might enjoy this magazine, it is cover to cover beautiful women wearing even more beautiful watches. And for you women, if your self esteem isn’t that great I wouldn’t pick it up, not the kind of expectations you want your teenage daughter to have for her body – it would be too disheartening.

As for you ladies, step aside, I’ll take the Chanel J12 Tourbillon Haute Joillarie featured in the magazine for myself, after all it’s only about a half a million as shown, more for the one above. The one I really want however is white ceramic with blue sapphires as featured on this blog, but it was a one of a kind, and I can’t afford it either – That’s the watchmaker’s Injustice!

P. S. Since, I’m a man and I don’t feel I can fairly judge this magazine, I have asked my wife to take a look at it and provide some follow-up. Look for that soon! Oh and if you like what you see here don’t forget to contribute to my blog. Thanks!

Happy Leap Day!

It only comes once every 4 years. Enjoy your perpetual calendars, should you have any.

Five films from Rolex

While visiting the “Timezone Rolex forum they mentioned five new videos on the Rolex web page. They are pretty neat short films about what goes into constructing a Rolex (sort-of). They cover the following topics:

  • The Movement
  • The parachrom hairspring
  • Everose Gold
  • Ceramic Bezels
  • 904L steel

Lessons from a day of watchmaking

About a week ago somebody called asking whether I could change a battery in a Baume & Mercier. I told him I could. We have the necessary case opening tool. He was ecstatic, apparently we were the 18th store he had called looking for somebody with the appropriate tool to change his battery. Today he came by because he was in town and we changed his battery, he was very grateful. It’s nice to be able to deliver a unique quality experience and have the customer truly appreciate it.

It should be noted that some Baume & Mercier have a unique keyed screw back, similar in nature to Rolex, but with more rounded grooves. It is just different enough that a Rolex wrench won’t open it and just uncommon enough that there are not a lot of generic openers like there are for Rolex. We used to carrier Baume & Mercier so we have their proprietary tool.

Yesterday a customer dropped off a Seiko quartz whose second hand was missing the marks every time. Today I went to adjust the second hand. I placed the hand precisely on the mark, but there is enough play in the gear train on this (and many inexpensive quartz watches) that the hand only hits the marks on either the rise or the fall, not on both. Luckily this one was really close in one direction and right on in the other direction (after I adjusted it). I hope that is good enough for the customer, it is all the watch will allow.

Today I had two watches which needed new power cells and water resistance tests. One of them passed the test and the other failed. The watch that failed was an older Tag Heuer, but that is a little bit unusual. Tag Heuers seem to be almost as good as Rolexes when it comes to passing water tests (of course the Rolex is by far a better watch and way more water resistant, it just happens that Tag Heuers meet their specifications consistently). Probably 1 in 50 Rolexes I test fails the water test the first time, but I quickly remedy the situation, it is usually due to some debris on a gasket that I overlooked. Maybe 1 in 20 Tag Heuers fails the water test the first time. I usually have to replace a crown and tube or crystal gasket to get them to pass. Today’s watch had a small chip in the crystal right at the gasket, so the crystal and gasket will need to be replaced but I am confident that will resolve the problem.

It amazes me how many people pass up a water test because, although Rolex and Tag Heuer do a pretty good job of passing water tests I have much less luck with other brands, the problems are almost always resolved, but with a simple power cell change and no water test the customer would discover this problem later, which brings me to the last watch of today’s post.

About 6 months ago I serviced a vintage Hamilton which came back today and was not running very well. I hate to see a watch come back; it just makes me sick to my stomach but it is always a learning experience. Today, however, the reason the watch came back was not my fault and not covered under warranty. Beneath the dial of this watch there was a coating of rust! I checked back in my records and I had informed the customer and noted on the job that the watch was not water resistant, but it clearly has seen some water. With vintage timepieces you really need to be careful. Even just washing your hands can cause a serious problem if the watch only has a dustproof crown.

Hand Pushers

Hand PushersToday for Tuesday’s Tools I present to you my hand pushers. They are very simple tools, but frankly you really need to have good ones. Hand pushers are used for installing hands on a watch. Well made hand pushers will keep you from marking the hands when you install them. This set are Rolex 2089. They are identical to a set of three Bergeon pushers. I also have some inexpensive black and white pushers from India, but they’re in some box somewhere because they are so poorly made I wouldn’t ever use them. The Bergeon hand pushers have replaceable tips and they are well polished and crisp. Each tip is different. There is a small solid end & a large solid end, four tips with varying size holes to accommodate the cannon pinion sticking up through the hour hand and the arbor for the second hand sticking up through the cannon pinion. Many students make their own set of hand pushers as a turning project in watchmaking school, but we did not. It would be easy enough to make a good set on the lathe in about half an hour out of acrylic.

Environmental concerns in the watchmaking industry

This is a topic I have wanted to expound on in detail for quite a while but I have a hard time finding the information I need. Here are some thoughts, nothing here can be taken as the gospel truth, it is all educated hypothesizing.

Common thought would lead you to believe that a mechanical watch is more environmentally friendly because we all know that batteries and electronics are evil ;)

Quartz watches:

  • The process used for creating batteries and their disposal generates toxins?
  • Billions are produced every year and therefore billions end up in the trash each year?
  • The process for creating semi-conductors is detrimental to the environment?
  • Many are produced in China and therefore less concern is given to the environment in their production?
  • Seiko & Citizen have very favorable environmental reports on their websites.

Mechanical Watches:

  • Mining metals is much better for the environment than producing plastics? :(
  • Mechanical watches last longer and therefore fewer of them end up in the trash?
  • They require periodic cleaning with toxic chemicals? – These same chemicals are used to clean quartz watches when they are serviced.
  • I have not found any environmental statements from manufactures of mechanical timepieces outside of Japan.

I really want to be able to expound on this topic so if you have any insight as to the kinds of questions I should be asking and where I might find answers please let me know.

Blu-Ray wins

I am a watchmaker “in a digital world.” I’m sure if you care you’ve heard already but Toshiba has decided not to continue pursuing the HD-DVD technology forfeiting the technology race to Sony and their Blu-Ray technology. So why did Sony win so fast when they fared so poorly in the 1980s VHS vs. BETA format war. The answer . . . Play Station. Sony ingeniously included Blu-Ray technology in their Playstation game console putting a Blu-Ray player into every house with teenagers. So, if you were waiting for the battle to end before you bought your next great toy, it’s over. Buy Blu-Ray!

What you get from a counterfeit

Disclaimer: I would never purchase a counterfeit watch, nor do I usually work on them which is why I am making this post. I will not be making a habit of discussing counterfeits here. I strongly believe that counterfeiting, like pirating, plagarism, and stealing to be unethical and wrong. I choose not to participate or support these activities.

With that out of the way. Today a friend showed me a counterfeit Panerai that he received as a “gag gift.” He thought I might find it interesting. Since I normally stay far away from such things I decided to take this opportunity to educate myself, my friend, and my blog readers about what you get from a counterfeit (besides a nagging conscience.)

Here is what I found:Fake Panerai At first look it is a nice looking watch. In fact from 5 feet away I might not know it wasn’t the real thing. When I first held it, it felt really light. The crown is extremely chintzy, when you unscrew it, it kind of wobbles and you can feel the sharp poorly finished edges of the knurling.

Take a close look and it just doesn’t seem right. We’ll start on the dial side. First it says 8 days and has a power reserve of about 60 hours without the horizontal power reserve indicator. Second, poor quality handsthe hands have the cheap stamped feel to them. The minute hand sits well above the cannon pinion and the luminous material is oozing out around the underside of the hands onto the sides.poor second hand

Flip over the watch to reveal some more quality issues. Take a good look at the full shot above (click on the picture for a larger version.) You’ll notice it seems dull, the movement seems to be ruthenium plated maybe (it’s very dark) the geneva stripes (or beijing stripes?) are very coarsely done and there is light scratching all over the movement. The lettering is crooked and some of the letters are poorly formed. There is a combination of flat and round headed screws (as well as white metal and blued). The beveled edges of the bridge are not polished and in fact there are many burrs sticking out still from the finishing process.

Zoom in closer and here’s what you’ll find.pan swan neck zoom The swan neck regulation screw is too short to reach the full domain of the regulator arm (in fact it isn’t even touching the regulation arm.) If the swan neck spring were doing its job it should push the regulation arm back against the screw.pan barrel teethThe barrel teeth are very coarse with burrs raised on nearly every one. I guess they didn’t have time to drop it in a tumbler to remove burrs before installing it in the watch. That jagged edge to the right of the barrel teeth is actually the threads on the case for the back (ouch!)poor oiling I only zoomed in on one jewel (kind of the worst example.) There is an oily substance all over the flat surface of the jewel (which should be perfectly clean.) Over time this oil will wick the oil out of the oil cup (where it belongs) and leave the pivot dry. All in all this movement represents a low grade Chinese copy of the ETA 6497/98 which I have heard are only semi-interchangeable with genuine ETA parts, it could prove difficult to find certain parts for this movement.

So, it is very poor quality. Would this affect the function of the watch? Definitely, over time those burrs will come free and clog the gear train or destroy the pivots or both. The fourth wheel will be running dry before too long, it won’t really be serviceable so it is basically a throw it away when it stops working kind of watch. So, you ask, “How is it running now?”

It has a 59 hour power reserve, pretty impressive. Well not really, it would appear as though they accomplished this mostly by putting a weaker and longer mainspring in the barrel, sacrificing amplitude for power reserve. They managed to squeak out an extra two turns of the barrel adding about 16 hours to the normal power reserve. Here are the timing results:



Timing
Full Wind
RateAmplitude
Dial Up+6245 deg
Dial Down+0270 deg
Stem Up+15215 deg
Stem Left+11215 deg
Stem Right+11225 deg

Half Wind
RateAmplitude
Dial Up+10225 deg
Dial Down+16215 deg
Stem Up+23190 deg
Stem Left+30185 deg
Stem Right+28190 deg

Average full wind is +8.6 sec / day. Delta of all positions over 24 hours is 30 seconds. I know for a fact that a stock ETA 6497 is capable of better than +2 and a delta of 10. I didn’t try and regulate this watch, but I’m sure whatever adjustments I made wouldn’t last for long.

My conclusion: The people who produce these watches are criminals (or at the very least not ethical. I don’t believe in supporting crime, especially organized crime. The watch isn’t that great. At best it is good for a single service cycle. Want to chime in on the issue of counterfeits, feel free to comment.

Micromechanics, Part III

Micromechanics I
Micromechanics II

With our first major exam behind us it was time to move on to the next unit. With winding stems we learned to cut stems on the lathe. Mostly right angles and flat surfaces. Our next task would introduce large tapers. We were to make a balance tack. The balance tack had a large flat base with a hole drilled in it and a long tapered cone, which had to be straight of course.

Next, we made a barrel closer out of acrylic. They key here was to have extremely fine turning lines so it would appear transparent. – This would be key for the next major project which was pivot gauges. With pivot gauges the key is to hit exact dimensions with burnished pivot shapes. The pivot gauges are cut from hardened and tempered spring steel (blue). Overall tolerances for dimensions on the pivot gauge were mostly +/- 0.03mm, but the pivot (the most important part) was always +/- 0.005mm. The pivot had to be burnished hard and with a blemish free mirror finish. This exercise simulates manufacturing a pivot on an axle that would run in a watch. The burnishing was carried out on a Jacot Tool. The pivot diameters started at 0.30mm and got smaller each time until 0.10mm for a total of 21 pivot gauges, not including exams and mistakes.

During this time I was also working on a screw head polisher. This tool is essentially a vise with three legs in which you can insert a pin vise with a screw to polish the head. It was constructed of brass jaws, steel runners and a steel thread with which to open and close down the vise.

Next, Watches I

Baume & Mercier Linea

Every once in a while a watch comes across my bench that surprises me. This week it was a ladies Baume & Mercier Linea.Baume Linea Let’s just say, that B&M isn’t a brand that brings quality and luxury to my mind, but I could be wrong. The case was made of a fine steel that polished up very nicely. The dial has a nice texture beneath the enamel and the styling is classic.

So, what’s inside? you ask. Baume Linea MovtInside is a well finished quartz movement with 4 jewels and Geneva Stripes. All in all a good buy and a good quality watch. It impressed me.
