Richard Mille RM 003

RM 003 is a manual-winding tourbillon movement manufactured by Richard Mille and co-developed with Renaud & Papi. It builds on the RM 002 architecture by adding an annual calendar complication that displays the month, date, and a second time zone. The annual calendar automatically accounts for months with 30 or 31 days, requiring manual correction only once per year in February. The movement was introduced in 2003 and has been discontinued.
