Rolex Divomet Prototype

You’re looking at the Rolex Divomet, a never before seen prototype pulled from the depths of the watch experts’ archive. Designed in-house and capable of calculating the depth of oceans or lakes, a bracelet passes through the Divoment’s circular crankcase which contains the mechanism as found in a Bourdon manometer. Interestingly, the watch features a bakelite outter ring, as found on the early GMT 6542s which was created at a similar time. The unique timepiece is coming up for sale at Christies November 15 Geneva sale and has a pre-sale estimate of $16,000 – $21,000.
