problem with setting the time on watch

[Richy]

Hi,

I have recently had issues with my datejust, where the seconds hand on dial won't stop on the watch when setting the time, the second hand keeps on sweeping, the hack feature did work before but now does not.

I'm concerned have i damaged inside parts of the watch?, other than that the watch seems to be working fine,



One other quick question if people have the time to answer:

when not using the watch is it ok to leave the watch dead and wind it up when using it? or wind regularly and keep it to run all the time.

Kind Regards,

richy
