Just the once Guy. Just began another test, due to stop 8am Saturday.
Yes fully wound till resistance.
You’re absolutely correct of course Steve.Amor Vincit Omnia wrote: ↑Thu Aug 08, 2019 6:29 pmI must confess, Paul, that I have never actually allowed mine to run down as a check. Probably the main reason being that 38 or 42 hours is neither fish nor fowl as far as I’m concerned.
Allow me to explain. I tend, if I am wearing them for a period of time, to wind manual watches first thing in the morning. With a 42 hour power reserve, assuming that I wind it at 6 am, it would be expiring around midnight the following day. No blinkin’ use at all. So I just wind them every day unless they are enjoying an extended sojourn in the box or safe.
Mmmm ok thanks Tim. Yep I wound about 30 times till resistance, got just under 38 hours.
Thanks Kip.Kip wrote: ↑Thu Aug 08, 2019 10:39 pmWithout doing research, my memory tells me that until fairly recently, the claims for most of these movements was 38-42 hours. Not sure when or why it changed, but if your going to wind it daily, as you should IMO, I wouldn't be the least bit concerned.
Wearing most of mine either 1 day or half day at a time, I couldn't tell you the reserve on any of them except the C9 5 day which I did check when received.
Thanks John. Appreciate your input.Bident wrote: ↑Fri Aug 09, 2019 2:58 amHi Paul,
I have let my blue C65 Trident Diver wind down at least a dozen times. I have probably checked it only 5 to 6 times, but in each case the power reserve was over 42 hours: around 45 hours or so.
There could be individual variations from watch to watch, but 38 hours seems a material amount to be off from the stated 42 hours. However, practically speaking, I personally wouldn't be put off by it and would keep the watch. But I would completely understand if others felt differently.

“Well, it ran for 46hrs & 5mins on one full wind.
It was +3 secs after 36hrs and +1 after 40hrs. By 45hrs it had slowed to -15 secs.
I’ll take that.”
I know that it will seem easy for me to say this, being as my power reserve was 46 hrs (no idea if that is repeatable without testing) but I have other watches that fall way short of the expectations and it doesn’t bother me. I’d only be bothered if they way say, out by 50% or so?
I’d view the quoted power reserves of any watch as “a ball park figure” rather than a guaranteed expectation.
I’d advise that you accept 38hrs as “close enough” and just enjoy the watch.
Having said that, I understand where you are coming from and if you can’t accept that sort of drift from the expectation, you could query it with CW.
I guess we are all a little like watch movements in that our “tolerances” are all different. I clearly got a “slacker” tolerance scale built into my temperament.
My C1 is just over 5 days which is good. Will post result of second test.DanielDZ wrote: ↑Fri Aug 09, 2019 2:51 pmMy 5-day power reserve ran for close to 6 days in general which left me feeling smug, so I get your point. That said, if mine ran at 38 hours despite being quoted 42, I’d be fine with it. Each to their own though, I hope your second test comes back with better results.
