Model Bubble Back
Reference number 2940 & 3131 Rolex Bubble Back
Type Crown/Pusher
Year of production 1950
Condition Unworn (Mint condition, without signs of wear)

Location Canada, Victoria British Columbia


Rolex reference numbers, 24- 8
There are crowns in stainless steel, yellow gold, and pink gold.
Rolex bubble back crowns circa 1950 onwards, these are easily distinguishable from the 1940s Bubble back crowns, as they have a BOX and a - (Minus) sign to show they were twinlock crowns. These crowns are for Bubble back models 3131 & 2940 amongst a host of other calibers and references., I would imagine these crowns are for the slightly LARGER sized (33 mm up to 36 mm versions, as they're all marked 8 3/4" ligne calibers) but, for all intents and purposes, they will cross fit a variety of Bubble backs. Please see pics
Dimensions are: 5,38 mm or 5,40 mm diameter of the crown/ 1,95 mm is the diameter of the tube.
Additionally, I have some generic bubbleback tubes if they're needed to go with the crown/ This is as a request only (For tubes)
