✈️ Get ready for the take-off with this dashing RichardMille! Designed exclusively as a flight navigation instrument, the RM39-01 features an automatic calibre RMAC2 which provides a second time zone and a flyback chronograph - the two vital complications for pilots. Aside from the complications, the case, baseplate and bridges are all forged with grade 5 titanium, making it extremely resilient to corrosion and very rigid. Richard Mille on the other hand introduces a locking crown system to the watch, a twist on the crown would lock the chronograph pushers, avoiding accidental activation. Last but not least, it also features the E6-B slide rule on the bezel, an aviator calculating instrument invented by Lieutenant Philip Dalton in the 1930s. Combining all merits into one, RM39-01 truly captures the modern essence of an aviator's wristwatch.
