GMT Master II Retro and Autowinder

[Plyskin]

I bought a Retro Ed GMT Master II SS Blue/Red (ROLGMT014) from Andrew. I have not yet worn it as its a gift.

I have wound it three times and placed it in an autowinder. The watch however stops without fail after about 33 hours. Its not the autowinder, since its a double and the Sub from SevenWatch has not missed a tick in three weeks.

I've written Andrew who states the GMT Retro does not work in the autowinder only on the wrist. GMT requires more aggressive wrist action to autowind.

Any thoughts? Do I have a lemon?

What type of winder is it? Some of them can adjust to various TPD (Turns Per Day)...there's a published schedule (orbita?) of recommended TPD for various types of movements... so if it's an ETA you could set the winder to the correct number of TPD and see if that works...

Possibility 1 - The movement in the GMT may need more turns/day than the Sub. Did you manually wind it 40 turns before putting it on the winder? If not, do so.

Possibility 2 - The GMT may need service.

Freddy & Shundi,

Two answers:

The winder is a Brookstone double. Only setting is on and off. 3 hours clockwise, 3 hours off and 3 hours ctr clockwise. Repeats the sequence.

I wound the watch as specified in Andrew's Q&A - 15 times.

the angle of the brookstone winder is maybe a bit too shallow to wind the watch properly, you might have a sticky rotor that requires a winder that is vertical or has a steeper angle.

The key to matching a winder to a movement is not the length of time it turns, but the total number of turns for a 24 hour period. Either your watch requires service or the winder is not providing a sufficient number of turns/day for that movement.

You can get a good indication of which it is by manually winding the watch 40 turns (slowly) & then wearing the watch for a couple of days. Assuming you are reasonably active during this time, if the watch stops, then it needs service. If it continues to run, then the winder is not providing sufficient turns/day (the guides that accompany some winders are NOT always correct).

Great! Thank you.
