I originally posted this over in the Café under the "Highlight of the Day" thread. This was the surprise I found while I was helping my parents move some sideboards and desks after they just had a new central heating system installed. As I was helping to put some drawers back in their desk, I noticed this wee gem sitting under a bunch of paperwork right in the corner.

I remember my parents had an old pocket watch that used to be my grandfathers, but the last time I saw it was about 20 years ago, and I didn't realise it was an Omega. Sadly the big cog was rattling about inside, so it does not work. My mum wants to see about getting it fully repaired and serviced, which is great new for me, as I didn't even have to ask.:-! I'm pretty sure this was the watch my grandfather used in WWII, so it would be great to get it back up and working again.:-!

Anybody got anymore info about this watch? Sorry about the bad pics as I only had my iPhone at the time.
