Hi! It's my first post here so I'll try and keep it nice and concise.

Basically, around a year ago I was given a watch as a 21st present, it's an old watch that my Dad was given by his Great-Granddad. I'm just wondering if anyone can tell me a little more about it.

All I know is it's an Omega De Ville in yellow gold and has to be wound up once a day to work. I've attached an imgur link with some photos of it.

I'm just wondering if anyone can tell me a rough date of manufacture and the like. I've done googling but I can't find this specific watch with this specific clasp on it.

Thanks in advance!
