Keep your Chronographs running perfectly

Keep your Chronographs running perfectly

I often read of people attempting to “self regulate” their watches to keep chasing that elusive dream of a mechanical watch that can match a atomic clock radio sync G-shock. While I myself don’t bother with such trifles or extreme OCD, I will admit it can be fun.

This is usually done with people resting their watches overnight either dial up, crown up, crown down, dial down positions. Depending on the characteristics of your particular watch you’ll see the watch losing or gaining a few seconds, you’ll just have to experiment to see what works best.

Here’s an alternate method I use because most of my watches are chronographs. If you have a chronograph with a sliding pinion movement such as any based on the ETA Valjoux 7750 or Lemania 5100 and your watch is running fast, you can get it running nearly perfectly. When you keep the chronograph running on such a movement, it changes the amplitude of the watch and it will usually run slower as a result. If you activate the chronograph for a few hours a day, you can probably get it running 0 seconds slow or fast. Again, you’ll have to experiment to see just how much you need to do.
