Here's my favourite from my collection. Seamaster 300. I have a few (inc 2 other Omegas) that are "better" but this was my first, bought it new in January 2002 which was a lot of money for me then and probably was my most costly purchase in my life to that date other than a car. Chrono24 estimates a 216% profit in that time.
I used to wear cheap watches, not long before this I bought a divers watch that was advertised on the back cover of FHM magazine. I think it was 200 quid or so but I cant remember the brand, I was on holiday with some mates in Malia and jumped in the pool and it got water in it
. In the heat in Malia it would condensate on the inside of the face and when it cooled during the evening it was just drops of water sloshing about in it. Embarrassing. Decided to get a decent one, didn't know much about them but I loved Goldeneye so I bought this.
Edit - bad maths - Coming up to 21 years old, so had it almost half my life. Been everywhere with me. Got some scratches, even a deep one on the face that I don't know how got there and the bracelet needs a makeover and pins replaced. Had it down to 30m, no leaks, obviously
Don't wear it much these days and the battery died in it about 2 years ago and had never bothered to get it replaced but got a new one put in last weekend and its good as new so will wear it all week. Keeps better time than my Planet Ocean which is worth 3 times as much. Battery lasts about 3 to 4 years as I think I have had it changed 4 or 5 times.
