Based on the advice of a few members here I sent my Aqua Terra off to Omega for a full service and to be honest I wasn't quite prepared for the quote that came back... nearly £1600!!!
Apparently not only is the date wheel mechanism shot, but the inside is also rusted to buggery and could well require a replacement module.
So I guess my new question is when is enough enough? Don't get me wrong, its a lovely watch and surprisingly subtle for something with a mother of pearl dial and diamond markers, but a part of me wonders if I'm better off cutting my losses and trying to recoup what it owes me.
Any input gratefully received, even if its only a comforting virtual pat on the shoulder...
