Mk 1 Trident cosc power reserve

Post by Douguitar » Thu Feb 06, 2020 8:20 am

Hello!

Forgive the question but I haven’t been able to find an answer here yet.
Background:
My Trident was bought in 2013 and has recently been repaired and serviced. It suffered ‘movement problems’ over the years relating to power reserve and accuracy.
Result:
It is now running at +/- 0 to 2 seconds per day so no problems there! (Although CW had it for four months). I am curious as to the best way to test the 38 hr power reserve. It was down to 21 hours, hence the repair, but I expect a marked improvement now.
Question:
Is it enough to simply power wind it and leave it to run, or should I wind and wear it for a few hours to fully wind it.

Many thanks, forum, for your time!
Regards.

I think you have your answer. I think we can underestimate just how much winding it takes, on or off the wrist, to fully charge a watch. I know from experience that just wearing a watch on a fairly stationary wrist doesn't do a lot.
I have the benefit of a winder so can rely on that to wind a watch fully.but as you cannot over wind a modern auto I'd say "wind it fully by hand. Then wind it fully again."
