To omega guru's i would like to know the reference no of this watch. It belongs to my late auntie.

 

Too few clue in here. We need inside case back picture (you should open it first, ask somebody with experience if you never open it) to see the reference number.
Unlike popular gents model, ladies model is more varied, less standardized and less known among collectors. Possibly it will not included in Omega Vintage Database as well.

 

Thanks for your reply Privateday7 once open i'll take a picture and post it immediately.

 

You are welcome. Omega has vast array of artistic lady style. Not easy to track. In term of movement caliber, possibly there is 482, 484, 485, 625, 671, or 684 inside

 

Not exactly the same, but has very similar bracelet to yours. http://forums.watchuseek.com/f20/help-identify-vintage-ladies-omega-238299.html
So possibly it has Cal 485,too.

 

According to Omega Service Center the reference no 8241 and caliber 485.
For this one model it can be done only on Switzerland.
