Overview
Tourbillon with dual time zone
Introduced in 2002 following the RM 002, the RM 003 adds a second time zone to the tourbillon movement. The home time is carried on a transparent sapphire disc running through the centre of the movement rather than on a subdial or additional hand.
Black numerals printed on the disc become legible as they cross a white section at 3 o’clock, and a pusher at 9 o’clock advances the display by one hour per press.
