Title: Question: How do you carry out a power reserve test?
Post by: epsilon82 on February 20, 2017, 04:27:43 PM

Hi All,

How do you all carry out power reserve test for your mechanical watch? How do we know the watch is fully wind? (Note: for watch without power reserve indicator)

Thanks

Fo me, I Just wear that watch at least 8 hours, it should fully wound the mainspring. leave it in a box untouchable. Write down the time (24hours) and the date/day you start leave that watch. Let say it is 2100 20/2 Monday.

Check your watch normally after 40 hours the mainspring will run out of power. Turn the crown to determined it is am/pm. For this example, 40 hours, your watch should stop aroud at 1300 22/2 Wed. It is a lot difficult to test the power reserve of watch without the date.

just wind 40-50 turns, most have over-winding protection.
then leave it alone in a box.

never assume a watch is fully wound just by wearing it...
i've read enough cases of ppl complaining their watch never reached full power reserve as they all assumed by wearing it for days that it had reached full power, then wonder why it died off overnight.

Depends on the movement,

Omega 8500 - around 90 turns and you will hear harsher sound (means fully wound)
ETA Powermatic 80 - around 80-90 turns
Others 38-48hrs PR - around 50-60, or you may feel the resistance

or put your watches into winder for couple of days continuous run in medium setting and test the PR.

Rolex manual wind movement: 1225 and 1601.
Vulcain manual wind movement: V10.

Their winding once full, you will not be able to turn the crown any further.
