Post subject:  Chrono Cockpit short power reserve
My chrono cockpit does not seem to have a power reserve of more than 24 hours.

Could this be because I did not wind it enough when I first got it and, if so, is it too late to give it a couple extra winds? I only bring this up because the dealer said to give it forty winds the first time and 10 winds every time it need it after that. I don't remember how many times I wound it exactly but I do remember not doing the full forty (it made me nervous for some reason).

If this is unlikely, does anybody know who I should contact to get it looked at?

Thanks

To test the power reserve, let the watch run down completely and then wind it at least 40 times - it's an automatic so you can't over wind it, heck wind it 400 times if you want. Then leave it alone and see how long it takes to run down.

Not sure what the 10 winds was from the AD - if it's a daily wearer then it shouldn't need winding at all, if it's just sitting then 30 winds per 24 hours are recommended.

OK, this isn't like undercharging one of those old cell phone batteries on the first charge, so they could never then be charged fully. By winding it only 10 times, you have not hurt it at all. The AD was suggesting you give it a fully wound spring by 40 manual winds.

Roff gave the procedure for testing the power reserve. If you only wind it occasionally at 10 winds per and and let it sit overnight and such, it wouldn't surprise me if it wound down after 24 hours. All arm movement will do is maintain the tension on the spring, not increase it.

Sooooooooooooooooooo wind away and let us know. :lingsrock:

Not bad for a theoretically 42-hour reserve watch. :thumbsup:
