"Limited to just 150 pieces each are a 42.5 mm chronograph and a 41 mm dual-time model, for $37,000 and $31,300, respectively. Both come equipped with in-house movements and feature a gray-blue-grained dial, highlighted with orange accents on the hands and other indicators. That orange also appears on the stitching of the Cordura fabric straps lined with nubuck calfskin. (Rubber straps are provided as well, and both can be easily swapped without the use of a tool.) The cases, bezels, pushers and pusher guards are all titanium, while the bezel ring is stainless steel; the only visible flourish is the 22-karat pink-gold rotor, seen through the caseback, featuring an engraving of Mt. Everest."
