Hello all at IWC forum. I have been collecting watches for many years now and have some great vintage and new watches. My wife was rifling through her late mothers jewellery collection and happened upon this beautiful little watch. It’s around 17 mm has what I believe is an 18k bracelet and a manual movement that still works well . It is from my wife’s grandmother who worked for De Beers diamonds. Judging by the inscription on the watch back it was for working for De Beers for 25 years. Any information on this watch would be greatly appreciated. Thanks in advance Graham
