Watch running slow on Winder. Bad winder?

[Cp827]

So I decided to test out a few watches that I thought were running slow. On Sunday I set my Daytona and sub to the exact time(time matching on iPhone) I have a wolf multi watch winder but never use it. Since the collection got bigger I just put every thing in the safe. I put my Daytona on my wrist and the sub on the watch winder(spinning both ways). 24 hours later the Daytona was spot on the time, sub had lost 5sec or so. 48 hours later Daytona was spot on sub lost total 10 sec or so. On the 3rd day i decided to take the sub off the winder and place it in the safe in the watch case dial up. End of 3rd day Daytona was spot on and the sub was still at -10 sec (didn’t lose any time since taking off the winder) 4th day same thing Daytona spot on still and sub was still -10 off the winder (no time lose off winder)
Has anyone else notice that a winder causes A time lose to a watch? Do I have a bad winder?

That’s because on a Winder the watch is held in a vertical plane and so may well lose time. It’s not a bad Winder.

Why have it on a winder if you have to set the time anyway ?

That’s not the point of a Winder. It’s not about maintaining COSC accuracy - it’s about not letting it run down and stop necessitating it to be wound. And please whatever you do don’t invoke the old you wouldn’t leave a car engine running analogy!!

Yeah but surely the point of net letting it get wound down is so that you don’t have to set the time before winding?

The only Rolex watch I would ever put on a winder is the Skydweller due to the AC complication and not having to reset the watch.

Ah ok never thought sitting vertical would effect it. Thank you

Thats why movements are tested at the Swiss COSC in 5 different positions to try and mimic what happens daily on the wrist.Regarding these so called machine winder things, really not needed with any Rolex watch.Now if you had a watch with many many complications then they could be a convenience.

Never knew that. Thank you. I Learned something new

Your watch ticks because of a wound mainspring. A separate watch winder cannot change the mechanics of the watch.

Sorry I’m confused. Your saying the winder isn’t causing it to slow down?

All the winder does is slowly rotate the entire watch, so, no - the winder is not causing it to slow down; it is not physically possible.

Timing may be affected by gravity/orientation of the watch, or it may be affected because while wearing it you are affecting it's basic timing causing it to run faster.

I would say that on the winder your watch is normal for that position - it cannot make it slow down or speed up. While wearing it, you are affecting it's basic timing causing it to run faster.

Great Info Larry. thank you so much for the lesson appreciate it!

The way a watch sits on a Wolf winder the pivots in the movement are at their greatest friction points. Hence the watch will lose time, as mine did also. Now if you set your watch dial UP at night during your 8 hours of sleep, you will eventually notice say after several days the movement will gain time. Because dial up is the least amount of friction on the movement pivots and axles. Even with a modern movement it makes a difference. FWIW my Wolf double winder now is a dust collector. With a single daily wearer watch, I no longer need it.

Thanks Jaime appreciate this great info. Helps me understand everything a lot better now. Yeah I agree a dust collector lol I haven’t used it in a long time too till I was running this test. It’ll sit there for awhile now no need for it.

Lot's missing information here. What happens when you wear the sub and put the Daytona on the winder? Does your winder have adjustments for Turns Per Day? I use a winder, and once you get your watch dialed in on the winder turns per day setting, it should be accurate. I always start on a setting that has the watch losing time, to few rotations. Then adjust turns per day have the fewest turns per day giving the best results. So you may need to adjust the winder settings. You mentioned you use the bi directional setting so that is doubling turns per day. There is a lot of anti winders here on TRF, but my watches are alway as accurate coming of the winder as they are on the wrist. Truth is however, I don't feel anyone needs a winder unless you want one, but mine was a corporate gift otherwise I might not spend the money for it.

If you have a big collection and you are ocd about time keeping then you will have a miserable time. Although yes -10 is not within tolerance but winders are unnecessary in the first place. You can give your sub a wind every other day. Problem solved.
