I recently purchased Sinn 556a (a gift for my father). I was testing it over last week and I see that it runs approx. 8 seconds / day fast. I was wondering if this is normal or I should be “concerned” ? I have received it on 14.06, have set the time and wound it manually. Since then, everyday I take it out of the box to wind it (was not worn, so it sits in same position all the time, dial up in the box). It is gaining about 8 seconds a day constantly. Yesterday time offset was 48 seconds (divided by 6 days = 8 secs/day). I have only one watch to compare to, my Steinhart Ocean 39 (Elaboré 2824-2), which runs 5 sec/days fast constantly over half a year. I was reading that Sinn uses Elaboré 2824-2 or even Top grade, so I was expecting it to perform at least at 5 secs/day. I still have time before father’s birthday in July, hence I wanted to hear your experience and see if I need to take it to watchmaker to, perhaps demagnetize, etc.. or this is normal and nothing to “worry” about J ?
Thanks for sharing your opinion!
