I've decided to buy myself a watch for my upcoming birthday, I'm looking at around the £1500 mark(I can stretch it a bit if I need to). At that price there is a mint condition 1997 omega Seamaster automatic(recently serviced) in a local jewellers. I'm also looking at watches like the tag aquaracer or the longines legend diver. I already have one tag and having tried them all on I just can't make a decision. Any advice?
