New to the forum but not to the Vintage HP world + HP-01

Thank you for the replies. I monitored the watch over a 24 hr time period. As base reference I use my iPhone clock. I set the time on the HP-01 and check it 30 minutes later and it's 2 minutes behind.
In other words the module is toast. That's a bummer.
I'll wait to get the other one and see what's wrong with it. Maybe between the 2 I can have a perfect one with spares to keep it going.
