Overview
Red gold case set with princess-cut diamonds
This RM 17-01 carries a 5N red gold case set with princess-cut diamonds, the setting running across the bezel and continuing over the caseband and the flanks, with the crown also set. The princess cut is a square step-and-brilliant cut; it is a cut rather than a point on the coverage scale used elsewhere in the catalogue.
The movement is the RM017 manual-winding tourbillon, unchanged in specification: 23 jewels in white gold chatons, 21,600 vph, around 70 hours of power reserve, with the power-reserve scale at 2 o’clock and the function indicator at 4 o’clock.

Design and engineering
- Princess-cut settingThe princess cut is square in outline with brilliant-style faceting. Stone count, total carat weight and grading for this reference are not published, and whether the setting extends to the caseback is not established.
- Gold case constructionThe case remains tripartite, assembled with 12 grade 5 titanium spline screws and abrasion-resistant 316L stainless steel washers, with two nitrile O-ring seals.
- Baseplate and bridges in grade 5 titaniumThe alloy is 90% titanium, 6% aluminium and 4% vanadium; baseplate and bridges were validated separately under resistance testing.
- Fast-rotating barrelOne revolution every 6 hours instead of 7.5, improving the ratio between power reserve and rate stability.
- Torque-limiting crownThe crown restricts applied torque to protect the winding stem and mainspring.
