Great post. One quick question is it ok to use a 900 tpd winder to wind Montbrilliant Olympus which says it take 650tpd. Just saw winder for 150 on Wolf Designs.

It sounds like your winder does four cycles of 150 turns each over the first 6 hours of it being on the winder and then nothing for 18 hours - a rather bizarre set up. The idea of the 12 hour delay is that turns early in the cycle are 'wasted' on a fully wound watch so the winder let's it run down first. Using math for your two choices (with or without the delay) gives:

No delay - watch is fully wound after 6 hours and then runs down 18 hours leaving 24 hours of reserve. It then loses 6 hours more per day and is done after 5 days.

With delay - watch is fully wound (just) after 18 hours - 12 hours of delay plus 6 hours of winding for 600 turns (the equivalent of 18 hours), but after that everything is the same - it's 18 hours down after 36 hours and then loses 6 hours more per 24 hour period so is done after 5 1/2 days - 1/2 a day better.

In terms of winding it when you put it back on, that depends. If you are very active with it on then putting it on after (say) 4 days may be sufficient to fully wind it, but in most cases you will simply add a little over 24 hours of reserve in a 'normal' day.

It sounds as though your winder does all of the winding in the first 6 hours of each 24 hour cycle after being powered on so to get the most out of it I would try to put it on to a timer that can give it two cycles per 24 hour period, each long enough for the winder to do three of its four 150 turn cycles. That way you can get 900 turns out of it with two roughly 7 to 8 hour rest periods in between.

I was thinking of an external power timer that can effectively turn the winder on and off twice in a 24 hour period and reset the cycle.
