I have a marvin Watch that i purchased some weeks ago ,and i have been monitoring its time keeping over a period of 36 hours it looses about 1 min 15 secounds,how does this compare with other wind up watches (not automatic).I have started winding the watch up fully every morning,is this ok to dophoto of watch, as you can see. I purchase the watch from Germany. It was in mint condition (dont think it has ever been on anybodys wrist).and the original box was with it.
