Thanks Al. The watch was running fast +17 sec per 24 hrs in the first couple of days (at various random positions). Over the last 36+ hours on the wrist it is running fast +10 sec. The watch appears to have settled into a fairly accurate trend and conforms to the target rate you describe.
I have another Speedmaster 4.5 and it is probably the most accurate watch I have (+-2 sec per 24hrs)
Thanks again Al for looking into this for me.
