If a watch runs well—it is clean, free of flaws, and running with good amplitude—it can usually be adjusted to be more accurate across different positions. And then we have… Read more »
At this point in the how-to series, it’s worth stepping back and contrasting dynamic and static poising to help illuminate the value of modern dynamic poising and even modern, smooth… Read more »
We need to find the balance wheel’s heavy spot to put it in poise. So far, we’ve discussed some of the principles involved in doing this and worked through some… Read more »
After reading the earlier posts in this series, you should understand the basic reasons why watches can have different rates across positions. But like everything else in life, you really… Read more »
The second task in dynamic poising is to align the 4 vertical rates. For vintage watches, the vertical rates usually differ by a lot. My trusty 12s Illinois, for example,… Read more »
The first step in adjusting to 5 positions is aligning the dial up (DU) and dial down (DD) rates. It doesn’t make sense to align the 3 vertical positions unless… Read more »
How do we go about adjusting a watch? This series of posts explains dynamic poising, an approach to positional adjustment that is nothing short of a watchmaking marvel. In this… Read more »
