This watch is very accurate, I synced to my apple watch to the second and day after day, the timing was precise! It’s a very fancy watch, premium quality! When sizing the bracelet get it a 1/4 size bigger than your measured wrist! If your wrist is 7 1/2 inches, size it for 7 3/4 and so on for any measurement! Keep on ticking Bulovers, because “America runs on Bulova Time.” Great Watch!
