I have collected vintage Bubblebacks and Canadian-version Rolex watches for over 30 years and this is the first time I’ve found such a cool and rare watch like this. To begin, this is the seldom seen flat-back 1940s Rolex Oyster ref. 2765 Bubbleback case (we used to call the tin can). Next is the very exotic and original Rolex Centregraph dial with extremely rare curved print and chronometer text. This exact dial has only been seen on the $50,000+ one-button Rolex Centregraph and here it is appearing on the time-only version! Rare ‘scientific’ and exotic dials tend to be found with this ref. 2765 case. Thirdly, this watch is stamped “chronometer” on the dial and houses one of their best manual winding movements at the time – adjusted to six positions and having 18 jewels. This watch is all original and correct – only the lume on the hands was re-done at some time. The correct Rolex Oyster winding crown is installed. The Rolex Oyster case measures a smaller 31mm but really draws attention to your wrist. This watch is pretty cool.
