I'm much enjoying this watch. It's very much a stealth watch in many ways. I appreciate its plain, classic looks but it really doesn't get noticed. Even other WISes don't recognize it until I tell them what it is. I'm wearing it about a workday a week, or about 5% of the time.
As of today (February 23rd), the watch is right on time.gov (NIST), which is to say, less than half a second off. HOWEVER.. the last time report had the watch +2 seconds, of which 1 second was the leap second. About two weeks ago, the watch suddenly lost two seconds. I have no idea what caused it; I would have noticed any severe shocks, and I'm not aware of being near any EM fields out of the ordinary.
Therefore, the accuracy so far over the 11 months has been -1 second. Still impressive, but I sure wonder about that time skip.
