Richard Mille is also a watch of choice for Tesla and SpaceX founder Elon Musk, per Superwatchman, besides his Carrera Calibre 1887 SpaceX Chronograph, a SpaceX collaboration with Tag Heuer back in 2012. His Richard Mille 029 is housed in a grey titanium case and bezel, with a black dial, silver-tone hands and black rubber strap. It uses a skeletonised automatic winding movement with hours, minutes, seconds, oversized date display at 4 o’clock and variable-geometry rotor. Chrono24 estimates that this model’s value can range all the way up to nearly US$500,000 for diamond-paved editions, with the above mentioned more “everyday” model still worth US$250,000 in mint condition.
