120s in 30 days = 4s per day which is within COSC levels (+5 to -2s a day). If you want 1s a month, quartz is your only hope (or resting the watch at different angles overnight which doesn't truly reflect the accuracy or otherwise of the watch!).

Edit: +6/-4 (see below). Oh. Red wine for lunch. drunk

and 4 seconds a day = 99.9954% accuracy.

Not exactly shabby.

2 minutes a month is less than 4 seconds a day which is within the COSC standard of -4/+6 secs per day (I'm assuming it is a mechanical movement)Just means you'll never be late for any appointments etc biggrin

Yes, why I put +5/-2, I am not sure.
