I had my watch for about 2 weeks and it had been running about 6 seconds fast/day. Now it runs about 4 seconds slow/day. Is that normal? Can that vary?
Hi there and welcome to OF!
Please provide us additional details of the watch.
There is a great discussion about this and there are many opinions about.
Watches run differently depending on service needs and position the watch is in. Need a lot more detail. Type of watch winding state age how you leave it over night etc.
