I don't know if anyone will believe it but, I decided to "time" my new Yachtsman, just for yucks. I paid NO attention to air pressure, temperature, etc., however I DID stand the watch vertically at night. I wind the watch (approx) 20-25 times in the AM when I place it on my wrist. Anyway in the 12 days of ownership - it is running 4 seconds slow. I check every day against NIST US time.

If I need any accuracy more than that - I'll put a battery in my old Accutron.
