Richard Mille RM 037

The RM 037 is an automatic line from the Swiss brand Richard Mille, built around its in-house CRMA1 calibre. It is recognised by its tonneau case, skeletonised dial with a large date at 12 o'clock and a function selector at 4 o'clock: winding and time-setting are engaged with a pusher rather than by pulling out the crown.

Versions differ in case material and gem-setting. In white gold there is the White Gold Black Onyx with a black skeletonised dial and the RM037 White Gold Snow Diamond Set (2024), whose 18-carat white gold case is set with a multitude of diamonds. The White Ceramic RM 037 (2025) is made of white ATZ ceramic with a white gold case section. The TPT® Rose Gold and Diamonds combines layered Carbon TPT with rose gold, with rows of diamonds on the case. The line also includes cases in Quartz TPT and TZP ceramic.

All these versions use the same automatic CRMA1 calibre, so the choice comes down to case material, dial finish and the condition of the piece. Among related lines, the RM 07-01 is worth a look.
