DynaStreetBob Posted February 23, 2014 Report Share Posted February 23, 2014 Is there a benefit to having a 'programmable' winder vs one that just spins. What is the recommended revolution rate for the an ETA 2836 or similar? Link to comment Share on other sites More sharing options...
calatrava Posted February 23, 2014 Report Share Posted February 23, 2014 Different movements require different turns per day to keep them wound. Some also are bidirectional winders vs. unidirectional winders. An ETA 2836 should have a TPD set between 650-800, bidirectional. Link to comment Share on other sites More sharing options...

An ETA 2836 should have a TPD set between 650-800, bidirectional. +1 But I have let's say a 7750 and a 2836 next to each other (same winding program) and they wind very good So here is my follow up question: Can you damage the movement by overwinding or underwinding the movement?

jpz5142 Posted February 24, 2014 Report Share Posted February 24, 2014 So here is my follow up question: Can you damage the movement by overwinding or underwinding the movement? It's my understanding that the auto-winding mechanism in the movement has a clutch that prevents over winding. It just slips when excessive torque is reached. AFAIK the effects of under winding on a winder is that the watch is slow.... Same as if you weren't active enough to wind it yourself, not enough power is in the mainspring.

droptopman Posted February 24, 2014 Report Share Posted February 24, 2014 Been shopping for a bigger winder since I have bought many more watches since finding this place Some of the better winders actually have settings for each wheel. For example an 8 watch winder holds 2 watches on each wheel. Could set first wheel at 800 for 2 ETA 2836 then have a different setting for the next wheel based on the movement. The winder I have now turns them all at the same speed with various movement and I have not had any problems with the watches, so not sure how important this is as jpz stated above may not make a difference. Just thought it was cool. Link to comment Share on other sites More sharing options...
jpz5142 Posted February 24, 2014 Report Share Posted February 24, 2014 Well, it might not be best to set the winder for the highest setting and put a watch on there and go away for a month before coming back. That sort of long span between putting the watch on the winder and removing it is probably best to find the most appropriate setting. I might have been out of line with my response, don't want to mislead guys with how to care for their watches. I was just thinking about the occasional over winding not the effects of perpetually keeping the movement at that high of power reserve. But what do I know about wonders, when I want my watch to keeps its power reserve when I'm not wearing them I give them to my sons (5 and 1) and they run around like wild banshees.

droptopman Posted February 24, 2014 Report Share Posted February 24, 2014 Jpz, hope you didn't take that the wrong way. In essence I was agreeing with you. I am no expert either. I do know my current winder is set at one speed (in the middle) and turns both ways. I have had many different movements on there including gen Rolex and Omega and I have never had an issue with any of them. Generally I run it during the day and turn it off at night. I have left it running with watches in it for 2 weeks or so while on vacation and did not notice any problems. You can see slight variations in time + or - depending on the movement, but not very much. Just trying to shed some light on the topic with some of the new winder features. Found a nice 8 watch winder on the bay (bunch of feedback here on the seller) with adjustable settings for each wheel for around $400 which seems to be a good price. Found a article on the net regarding turn speeds for different movements. I will try and find it again and post the link. Link to comment Share on other sites More sharing options...
