My Gen 2 was my first Omega, purchased to celebrate my 30th. Picked it up in an Omega boutique in Switzerland as well. It wasn't well loved or popular back then, often considered an overpriced Quartz on forums. Good thing I've always purchased what I liked, not cared about resale value and simply enjoyed my watches.
It was my daily wearer for 8 years before I switched to a slightly dressier De Ville mechanical. In those 8 years it travelled with me to many countries and took its share of beatings. It's been swimming with me many times so don't believe all the prattle about it barely being splash proof. I even put deep gouges in the bracelet after owning it for 6 weeks at a belated birthday bash where I got very drunk and fell into a stone curb in central London somewhere. Good thing a full service back then only cost £150 and included refurbishing the bracelet!
At the last full service several years ago I even had it upgraded to the latest 1666C movement with thermo-compensation. The accuracy has slipped a bit to maybe +15-20 SPY (seconds per year) but it's on it's 3rd battery now. When it first came back from service, for that battery it was <8 SPY. The rate of gain is very constant so I'm sure if I had it serviced it could be tuned back.
I don't intend to ever sell it and would be glad to hand it down to one of my sons if they ever show a keen interest in watches. If you can find a good example of a Gen 1 or 2 then it's definitely worth adding to a collection.
