Another 1846 Chrono winding issue
I have just recieved my new 1846 38mm from my AD. The piece seems not to wind over nite on my winder, and only slightly during wearing. Does anyone else have this problem. I have tried clockwise and bi directional setting on the winder. I do not think this is a counter clockwise movement. Any Ideas
Some more info needed ...
The 1846 Marine Chronometer uses a movement based on the ETA 2892A2, which has a bidirectional winding system. It thus is not really important which winding direction your winder is set on.
To evaluate if your watch has a mechanical problem, I would need some more information:
a) Can you wind it manually, from the power reserve showing "down", all the way to "up"?
b) If you leave it on the desk, how long does it run after having been manually wound?
c) What are the exact settings of your winder? Does it spin continuously, or once every minute (or similarly)?
d) What is the position of the power reserve hand when you place it on the winder?
e) When wearing the watch, do you wear it in the office only? during sports?
Generally, the purpose of electric watch winders is less to wind a watch movement to full mainspring tension from "empty", but more to keep the energy level the watch has when you place it one the winder. Consequently, most winders need a higher setting, when you really want to "load" your watch.
Additionally, it needs a lot more energy to get the power reserve from "half" to "full", than it needs to get it to "half" from "down". You can check this yourself: Just count the turns of the crown necessary to wind the movement from "down" to "half" to "up".
Of course it is also possible that the watch has a mechanical problem. while the ETA movement is well-tried and has proven its reliability since many years, in many, many watches, it still has some sort of "achilles heel" in its winding system. Sometimes, a specific (reverse) wheel in the winding train can show excessive signs of wear on its teeth, resulting in an inefficient winding. If this is the case, the repair should be easy and quick. If you have a factory new watch, this is rather improbable, though.

Thanks
Thanks for the info. I talked to a watchmaker at UN USA today and he immediately wanted the watch back to repair at UN's cost. Very professional. Promised a 3-4 week turn around. So far I am very impressed.
Once again thank you for your follow up.
Once again thank you for your follow up.
Good to hear that the watch is taken care for ....
... please keep us updated about the issue.
