My Grandads Comex Oyster Perpetual Submariner.....

[Andyb83]

Hi Everyone!

This is my first post to the forum, and i hope ive got the right thread!

Ive been researching my grandads old Rolex Oyster Perpetual Submariner, and have come to find some of the comexs are quite rare and was wondering if anyone could shed any more light about the watch as i cant find any which look quite like this one!

The detail are basically this : A Rolex Oyster perpetual Submariner, 660ft - 200m. It has swiss t<25 written at the bottom of the face, but doesnt have comex anywhere on the front. On the rear it has in big letters Rolex and Comex, and underneath a lot smaller the number 118. It also has what a believe to be a helium release valve, and the braclet is stamped with the numbers 9315 and 280?

Im currently at work, but ill get some pictures on here as soon as i can. Thanks for any info in advance
