Royal Oak Jumbo Extra-Thin 39 Steel Blue Dial

The One That Started It.

A blue Petite Tapisserie dial in a steel case just 8.1mm thick, with the integrated bracelet tapering to nothing at the clasp. This is the reference closest to what launched in 1972 and the reason everything else here exists.

The movement is an ultra-thin automatic with a full gold rotor, which is what keeps the case as slim as it is.
