Hi bros,

Full wind is about 28-30 wounds. Power reserve is between 48-50 hours long.

After 30 wounds I can roughly get 15-18 hours. I guess my speedy is having issue right. Btw, how do u define I full wind? Thanks for sharing as I am newbie to manual winding watch.

Full is when you can't wind anymore. You should be able to feel it.

Hi all,

Thanks for your inputs......

Juz an upadate.. after fully wound my watch 2 days ago and timed it, it lasted right at 50 hours & 45 mins this morning (almost can get 51 hours) but if i am not wrong i should have wound my watch more than 50 winds to hit the stop gate (definite stop).
