Let me limit things a little. Consider only (mechanical) three hand watches with no tourbillon currently in production. Given that the watch will be worn during the day and placed in an orientation for the rest of it, which watch would it be? This is due ...
About +0.5 sec/day. Although, outside your specs, this came back from service and is regulated so well that in three weeks I cannot see any deviation at all: Best Andreas...
I can only speak to my sample. I have read others with the SC post anywhere from 1-3 seconds/day. Mine seems to run the same whether I wear it a few days in a row or let it sit. Other watches I have owned seem to run more accurately one way or the other, ...
My Habring have been running since July, and is currently +10s (so that's roughly +2.5s/month). The trick is to find out the best winding position that allows minimal time gain/loss. For me, I always wind my watch daily (given it has 48 hour power reserve...
Any watch can be highly accurate if its positions, state of wind, etc. are carefully controlled. For me the question is which watch functions best (a) when stored in inconsistent positions; (b) when sometimes worn and sometimes left on the winder; and (c)...
Okay, I would say Grand Seiko VFA, but it is 40 years old. It requires very diligent and experienced adjuster to make the most accurate watch + picking up the "better" movement example. Many brands could do it, if they are willing to spend such talent and...
...this one was built for the purpose of accuracy contests, so it is reasonable to assume that it was once extremely accurate. It is a bit highly strung, however (e.g. no shock protection) so has probably fallen out of tune in recent times. Still, you wan...
