Richard Mille is releasing a new world timer watch after their RM 58-01 from back in 2013, and this one is called the Richard Mille RM 63-02 World Timer Automatic. It is not a tourbillon, but it has got a brand new in-house movement, and this new world timer still sticks to the philosophy of the brand that the watch should be as easy to use as possible. This was achieved in part by removing the need for a pusher when using the time zone function: the satin-brushed and polished grade-5 titanium rotating bezel is actually set on ball bearings, allowing easy adjustment when the wearer is setting a time zone. The rotating bezel also has a wheel connected to the movement which directly manipulates the hour hand, increasing time-setting accuracy and speed. When you’ve set your city to the 12 o’clock position, the watch will have the 23 cities set in their time zones referenced against your home city.

Taking a look at the dial, you’ve got the two outermost rings which are, naturally, for the time zone cities, and for the world time indication – with dark blue for PM and white for AM on the 24 hour scale. You might miss it at first, as it is set among two skeletonized discs in the same gray color, but there also is a date indicator right under 12 o’clock – which can be adjusted by a push button at 10 o’clock. The large, center piece of the dial is a 0.40 millimeter thick plane of sapphire that has been put through the anti-glare spa treatment, so that legibility remains good – and that the skeletonized movement plates in titanium underneath are easier to appreciate.

The new in-house automatic CRMA3 movement has 37 jewels and features baseplates and bridges which are made of the aforementioned grade-5 titanium which is also treated with electroplasma in order to improve rigidity and surface flatness. The balance spring has variable inertia to help shock resistance, and they’ve eliminated a regulator index in favor of four small, adjustable weights on the balance spring. Richard Mille’s CRMA3 movement has a fast rotating barrel that completes a revolution in five hours as opposed to seven-and-a-half, wound by a 5N red gold and titanium rotor. The benefit of this, apparently, being a reduction in internal mainspring adhesion as well as creating a mainspring delta curve with an improved power reserve/performance and regularity ratio. This ratio may be improved, but power reserve is significantly less than the 10 days in the RM 58-01, with the Richard Mille RM 63-02 World Timer Automatic having a 50-hour power reserve.

The CRMA3 movement uses special gear teeth which have wheels that use a 20° pressure angle. This helps with negating any discrepancies between the wheel centers caused by normal use or thermal changes. Something else that makes this movement special is the use of flat-head screws with 6-holed heads as well as grade-5 titanium spline screws to provide better torque control during assembly.

The case of the Richard Mille RM 63-02 World Timer Automatic comprises almost 200-parts – and, again, that is the case only. Coming in at 47 millimeters wide, it is actually a little smaller than the RM 58-01. The crown is similarly made of titanium and is finished with polishing and microblasting with an O-ring seal and Alcryn collar. The sapphire crystal has anti-glare on both sides. You’ve got 30 meters of water resistance (though I don’t think anyone is going to be going for a swim with this on), with the aid of the rotating bezel which actually ensures the water resistance. This watch is classic Richard Mille, and it’s currently being shown at the SIAR (Salón Internacional Alta Relojería) between October 20-22, 2015. The price for the Richard Mille RM 63-02 World Timer Automatic watch is $145,000. richardmille.com
