: Hi,

: I purchased a new omega seamaster (automatic
: movement, co-axial) in May 07. Until
: recently the watch gained between 1 and 2
: seconds a day. In the last few days for no
: apparent reason and without any change in
: the way it is worn it has started gaining 6
: seconds a day. Is this behaviour normal?
: Would be grateful for feedback.

I know you said you haven't changed the way the watch has been worn, but have you possibly been keeping it in a different position overnight (crown up, crown down, face up, etc.)? This can alter the timekeeping of the watch, which is why it's good to experiment with different overnight positions when you buy a new watch. This allows you to find the best position for your particular watch.

Also, if you don't wear the watch for very many hours each day, you may want to give it a full manual winding to see if that makes any difference. To do this, unscrew the crown and keep turning it until you hear a faint clicking noise as you turn. This is the overwind protection mechanism engaging, meaning the watch is fully wound.

Gaining 6 seconds per day puts the watch right at the top end of the COSC specs (-4 to +6 seconds per day), so I would definitely keep your eye on its timekeeping for the next week or so. If it gets worse, you can send it back to Omega for a factory regulation under warranty. Since your watch is a certified chronometer, Omega will regulate it free of charge if it deviates from the COSC specs.

Good luck,
John
