Pegging out jewels

What is pegging out jewels? This describes the act of using a small piece of wood to clean out the inside of jewel and bearing surfaces before putting the watch in the cleaner. This is really important, especially when the oils have dried up in a watch movement. It’s kind of like scraping off some of that really stuck on food before you put a plate in the dishwasher. Although my cleaning machine is great, cleanliness here is critical. As a general rule the jewels should look clean before they go in the cleaner.

I remember reading an article which claimed that pegging out jewels can increase amplitude by as much as 50 degrees. I believe it! Sometimes the junk in those jewel holes is pretty sticky and I don’t think there is anyway swishing it around in a solution would be enough to loosen it all up.

So, if you’re going to work on watches, peg out those jewel holes for better results. There is no place for cutting corners in watchmaking. 🙂
