I own a Seamaster ProDiver Titanium with a serial number of 80149725. I cant recall which year I bought it, and of course I lost original box + associated paperwork...I believe it was 2002, just wanted a confirmation of the year it was made...Thanks...

But using these Omega serial numbers puts this watch between 2006 and 2007?

 

You really can't use serial numbers for a watches age unless there's a documented classification by the manufacturer like Rolex and Panerai. Besides, how do you even classify a watches age? When the movement was manufactured, when the movement was put into the case, when the watch was packaged, when it was shipped, when it was placed in a dealer's stock, when it was sold?
But just by the features of your watch it had to be before 2010.

 

I guess so. And of course you can always say that the watch must have been made before it was sold!
For example my SMP was bought by me new in 2000 and has a seriel number (case and movement) that is 80,146,xxx. Yet my Speedmaster that was bought by me new in 2007 has 77,146,xxx.
Go figure.
