In making the Lunokhod watch, Konstantin Chaykin used a material previously unknown to watchmakers – genuine stainless bulat steel, a specially melted steel with a high carbon content, an exotic and rare material that is considered legendary and even mythical, incredibly difficult to work with. Bulat steel has a unique crystalline structure that makes the metal incredibly hard and wear-resistant. The surface texture also makes the watch case unusually attractive, giving the watch a brutal character and even a militaristic look to a certain extent. With the Lunokhod watch, Konstantin Chaykin has created the largest and most realistic-looking moon in the world for a wristwatch. The 12 mm spherical moon in the center of the dial is made of bulat steel, whose surface texture resembles the relief of the moon’s surface. The caliber K.05-0 of the Lunokhod watch was developed by Konstantin Chaykin and is equipped with a natural spherical moonphase indicator. The movement is made entirely in Konstantin Chaykin Manufacture according to the standards of haute horlogerie, using traditional techniques for finishing the components: Côtes de Genève, perlage, fine straight and circular grinding, hand-polished chamfers, engravings, polished screw, pin and jewel recesses, ball polishing of the pivots and rhodium plating. A special feature of the movement is a ‘Pac-Man’ regulator, developed by Konstantin Chaykin for fine adjustment of the hairspring. Caliber: K.05-0, hand-wound, made by Konstantin Chaykin Manufacture Power reserve: 38 hours Functions: – Hour display integrated with day/night indication; – Minutes; – Natural spherical moonphase indicator The Lunokhod watch has a very complex shape. In profile it looks trapezoidal, just like the moon rover that inspired it, and the triangular reliefs on the caseband are reminiscent of the moon rover's wheels; similar reliefs can also be found on the crown. The top of the case is spherical, like the Lunokhod moon rover. Case dimensions: Diameter 47.7 mm; 10.7 mm thick (not including the spherical sapphire crystal over the moonphase indicator)
