Watch Slow on Winder ?

[Texcowboy9]

I wonder if anyone else has experienced this. The Speedmaster Reduced that I had (sold it to fund the Great White) would run a good bit slower when on the winder than when I would keep it face up in the watchbox and wind it every morning. Now I find my Great White seems to follow along with that pattern. I assume this is because when stopped on the winder it is face up but at an angle and varying degrees. My 2254 is not affected by the Winder. The winder is an inexpensive one but turns different directions and stops and starts on its own, it is a two place. My other winder is a one place on which i keep my Rolex, it starts and stops on its own but I have to set the direction in which it turns. My Rolex is amazingly accurate and not affected by being on the winder.:-s

I have just one, cheap winder which I use more as a display box as anything else...but I have noticed that both of my automatic Omegas (2220.80 and Great White) run a bit slower on the winder than if I rest them dial up. But the performance in the winder is comparable to what I get if I rest the watches on their side (i.e., crown up or down), which seems to make sense.

The price of the winder has nothing to do with a watch movement going faster or slower.

Watches are sensitive to positional variation and to how fully wound they are - some more than others, some less. This is dependent upon all sorts of variables, so your results will vary. Generally though, a movement with the finest components, made to exacting specifications and expertly regulated and adjusted at the factory or by an expert watchmaker will run with much greater accuracy and precision.

Regulation and adjustment are different:

Regulation refers to the process of touching up the variable parameters on an escapement -either the moment of inertia of the balance wheel, (used by Rolex, PP, etc.) or varying the effective length of the hairspring via the adjustment lever, (used by most other watches)- so as to minimize the average rate error of the watch.

Adjustment is something generally done only by the manufacturer at the time the watch is fabricated. It refers to the meticulous balancing of the balance-wheel/hairspring system so that its center of mass is always located along the axis of the balance staff.

Hope this helps.
