Catalogs

I’m not just a watchmaker. I love watches too. I try not to dwell on them too much here because if you check out the blogroll there are plenty of people blogging about every new watch that hits the market. I do however want to spend today writing about watch catalogs.

As a watchmaker I like watch catalogs for several reasons:

  1. They make great reading material at lunch ­čÖé
  2. They help fill my dreams at night.
  3. The serve as a historical reference of watch models. It is important for me to know if a watch is authentic or not. I’m pretty good with Rolex, but when it comes to other brands it becomes more tricky. Catalogs prove to be a great reference.

There are also some other great references. Every watch collector and watchmaker needs a copy of Cooksey Shuggart’s Complete Price Guide to Watches. I also like the Wristwatch Annual. For Vintage Rolex Sport Models the book with the same name works well. I don’t have a really good reference for other Rolex models yet, if you can recommend one please feel free to comment.

Gerald Genta┬áCatalogBack to Catalogs. The holy grail of watch catalogs is the Rolex Master Catalog which is difficult to get because Authorized Dealers (in the U.S.) are required to return their previous year’s catalog to get a new one. Many watch companies make beautifully bound catalogs available to their customers, simply by asking for one on their web page. Today, I received in the mail a beautiful catalog from Gerald Genta (those aren’t noises in your head when you visit the site- they come from the web page). I could never afford one of their watches (see Watchmaking Injustice) but they are things of beauty as is the catalog. If I could afford one I would definitely go for the Fantasy Model RSF.X.10.143.LB.BA featuring jumping hour, retrograde minutes, sweep seconds and Mickey Mouse in an aviator’s theme. About a year ago I received a beautiful hard bound catalog from Jaeger-LeCoultre. In order to get Rolex’s customer catalog you will need to hit up your local authorized dealer, it is beautiful as well, but very incomplete. Some dealers also have great catalogs like Hamilton Jewelers in Princeton, NJ and Wempe. One last place to get great catalogs are auction houses. The catalog for Antiquorum’s upcoming Rolex themed auction The Evolution of the Rolex Sports Watch” is 488 pages of fabulous Rolex knowledge and it’s available online and for download as a pdf file or you can purchase the catalog in hardcover. Oh, and if you want to make my day bid on those Rolex cufflinks (Lot 10, pg 20) and send them my way ­čÖé

Whenever I see a beautiful catalog available I try to get one to add to my collection, I’d like to build a historical record because I know it will be valuable in my profession. Oh and they are fun too.

What happens to my watch when it is serviced?

So you decided to get your watch serviced, but you were shocked by the price. Let’s talk about what you get for the price.

Omega┬áPWWhen a professional watchmaker services your watch his job is to bring it to like new condition — This isn’t always possible but we try our best. What you say? Not always possible? Sometimes a watch case has a huge dent in it and removing it would cause way too much wear on the watch to warrant it, so we pretty up that section a little bit taking care to make the rest look perfect. And, then there is the issue of parts. When parts aren’t available what does one do? Not replace worn parts, make new ones, use generic, or turn down the reapir?

So back to the service: It usually includes a complete refinishing of the case and bracelet (not to be confused with polishing.) Sometimes an individual will polish a watch case and make it “shiny.” Refinishing the case means applying the same finishes as original in a clean, crisp manner and can take anywhere from 10 minutes to an hour depending on the specifics of the finishes applied. Your typical Rolex case and bracelet requires 3 different polishing compounds, 5 different finishing wheels, a lathe for refinishing case backs and tape to mask off the polished center links when applying the line finish to the outer ones. It is a labor intensive process.

HammyServicing the movement requires detailed and precise work. The watchmaker shouldn’t leave any marks on anything. The dial and hands are removed, the watch movement is pre-cleaned and then every component is carefully examined under magnification for flaws as the watch is disassembled (there are well over 100 parts in most watches). All worn components are replaced and all faults are corrected at this time (except for timing.) Jewel holes are pegged out and pivots are cleaned in a block of pith wood. The disassembled watch is then put into a special watch cleaning machine which combines agitation and ultrasonic frequencies to clean the parts. The parts generally go through one wash cycle and two or three rinse cycles before being air dried. The parts have to be perfectly clean!

Once the parts are clean they are never touched by hand. The oils in the skin could damage the parts and small flecks of skin are enough to bring the gears in a watch to a grinding halt. The watch is carefully assembled and each component is again examined under magnification to be sure there are no defects. As the parts are assembled each function is checked to make sure it is working correctly and the watchmaker is careful to make sure no foreign substances are inside the watch. I find dandruff to be a real problem, I’m always finding little white flakes which I have to remove carefully. You can watch the video at this site for a feel of what goes on during assembly.

Special lubricants are applied to all the bearing surfaces in the watch in a very precise manner according to the manufactures instructions. Too little means the watch needs to be serviced again prematurely, too much means the oil runs everywhere and gets on parts that can’t have oil. A typical watch requires five or more different lubricants, all must be applied in the correct areas.

Once the watch is assembled the watch is put on a timing machine to check its rates. Careful adjustments are made to the hairspring and regulation device to ensure the watch keeps good time.

The dial and hands are again placed on the watch and the movement is placed back in the refinished case. All the gaskets are replaced and the watch (if it is water resistant) is pressure tested for water resistance. The watch is then observed for several days and any additional adjustments are made to the timing of the watch.

The end result is a beautifully restored watch which is ready for another five years of service.

Should I run my chronograph all the time?

Monday Myth Running my chronograph all the time will cause it to wear out sooner. Is this true? Short Answer: No

There are many different kinds of chronographs: Quartz, Mechanical, Two function, Three function, Column Wheel, Cam, Sliding Clutch, Vertical Clutch, integrated, modular. What do they have in common? For all of them the answer is no, running your chronograph all the time will not cause it to wear out sooner.

A chronograph is a watch which has an additional complication which allows you to record elapsed time, usually by pressing a button to start the timer and to stop it.

ETA 251.272┬áChronographThere are two basic quartz models of chronograph. One has 4 or 5 motors (one for the time of day, one for the seconds counter, one for the minute counter, one for the hour counter, and one for the division of seconds if equipped.) The second kind has a standard quartz movement with a mechanical module added on to the dial side of the movement adding the chronograph function. Running either of these all the time will cause your power cell to deplete faster but the forces are so small that the parts aren’t going to wear out any sooner because you are using them. These parts will need to be serviced the same time as the other quartz components.

Mechanical Chronographs have much greater forces throughout. The basic movement has a fairly large spring providing power to the gear train forcing it to rotate. When not properly lubricated and/or dirty these parts can be ground into nothing (see post on servicing). With each gear the forces are reduced. The chronograph mechanism is usually driven by the fourth wheel (whose forces are not terribly great) and as we continue through the chronograph mechanism the forces get smaller and smaller. When a watchmaker services these components he cleans and lubricates them in such a manner so that they should be able to run for 5 years without causing any wear (assuming the watch remains clean and dry). We apply the same principles to the chronograph section as we do to the regular gear train. Since the forces are smaller in the chronograph train it should be able to withstand the same period of service. When the chronograph is disengaged the wheels don’t turn (and therefore don’t have any chance of wearing) but when it is engaged they don’t turn any more than the base movement. Your base movement will begin to wear out or stop working well before the chronograph parts begin to wear.

With a vertical clutch chronograph like in Seiko chronographs or the Rolex 4130 the clutch actually slips when the chronograph is stopped, potentially causing this part to wear more when the chronograph is stopped than when it is running. This part is still designed to perform well for the same service interval as the rest of the movement.

The bottom line: Have your watch serviced every 5 years by a qualified watchmaker and nothing will wear out, chronograph or otherwise.

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

Watch Maker? or Watch Repairer?

Rolex1400Some days I feel like a watch repairer or a watch technician. Other days I feel like a real watchmaker. Today was a watchmaker day!

Today I worked on a Rolex Caliber 1400. It is a small movement. As you can see from the picture it is smaller than a dime, but it isn’t the size that made me feel like a real watchmaker. This movement need a new balance staff. If you look at the full size image, you’ll see a little ‘something’ in the background between the movement and the dime. (That is the old balance staff.) To fix this watch I had to remove the old staff. This involves removing the hairspring and roller from the old staff. I chucked up the balance wheel in the lathe and cut out the old staff and riveted in a new staff. I then re-installed the roller, trued & poised the balance wheel, and then reinstalled the hairspring.

When I got done with the whole operation, I stopped to think. I didn’t even second guess myself because of the size. I simply did it and did it right. I guess today I’m a real watchmaker. I know I didn’t make anything, but I performed a complex operation on a very small watch and I did it right the first time without second guessing myself.

A big pat on the back for me!

Basel World Predictions

I’m going to put myself out on a limb and make some predictions for Basel World 2008.

Prince

I don’t have any insider information, this is kind of what I’m hoping for and I think is plausible.

I work with Rolexes on a daily basis, and I am a big fan. I went to watchmaking school at the Lititz Watch Technicum. I graduated with my WOSTEP certificate, my LWT diploma, and my AWCI Certified Watchmaker in hand. I received a very broad and generalized education followed up by some very specific Rolex brand training, so my opinions are not unbiased.

I like Rolex because their movements are solid, rugged, dependable machines and their styling is timeless. I don’t like all there models but I do have some favorites. Before I make my predictions let me share some of these with you (in no particular order) ­čÖé

Steel & 18K Everose gold Turn-O-Graph. I like the Turn-O-Graph because it is dressy but still has the added functionality of a rotating bezel as well as the date. Probably one of Rolex’s most under appreciated models.

I love the Datejusts on a strap. Probably my favorite is the white gold Datejust with the decorated blue dial with arabic numerals. Classy! (Shown of Rolex’s web page in yellow as option #8 if you follow the link.)

I love the Cellini Prince. My favorites are the rose gold and the white gold with the black and red dial (rayon flamme de la gloire = flaming rays of glory).

From a technical stand point the new Yachtmaster II is an incredibly complex watch with awesome functionality, even if you don’t participate in yachting regattas. Great for board games.

On with the predictions!

1. I asked a Rolex executive if we would see the ceramic bezel and wider lugs from the redesigned GMT-Master II on the Submariner. He replied, “We don’t have any plans for that yet.” To which I said, “Until Basel in April ;)” His reply, “We usually let Basel break the news.” I predict we will see the Submariner with a ceramic bezel, it’s an obvious extension.

2. I expect we will see another really large watch. The new Yachtmaster II measures 43mm which is much bigger than Rolex has gone before. This year I think we’ll see the Sea-Dweller in an oversized case with a rubber strap. After all they missed the 50th Anniversary of the Deep Sea Special in 2003, why not release a 55th Anniversary edition?

3. I’d like to see the Daytona Cosmograph redone, possibly in a large 43mm case but I expect that will wait for the 2011 50th Anniversary of the Cosmograph.

Okay, I’ve put myself out there. Remember I have no inside information, this is just wishful thinking.
