Richard Mille has announced a limited edition version of their thinnest timepiece, the RM 016. The titanium case measures only 8.25 mm thick, which makes this a great dress watch that can easily fit under a dress shirt or suit. The black DLC coated titanium case is 49.80 mm x 38 mm, which is the brand’s only rectangular timepiece. Richard Mille originally introduced the RM 016 in 2007, and it was very popular due to its ultra-thin case design that is specially tapered to fit the wrist very comfortably. The machining of the case’s three sections requires 202 separate machine operations.

The movement features Richard Mille’s signature variable geometry unidirectional rotor that allows fine-tuning of the rotor’s winding. The automatic movement is skeletonized, something you can pretty much expect from any Mille timepiece. Sapphire crystals are used on the dial and case back. The power reserve is 55 hours.

The dial comes in either bright citrus yellow or orange hues that outline the numerals and hands while contrasting nicely with the darkness of the DLC case. The strap, for the first time, is available is a sporty and comfortable black rubber. Water-resistance is 30 meters. 15 pieces of yellow and 15 pieces of orange will be available at authorized dealers in North and South America.

Retail is $65,000.
