SJ Production presents the GS brand, which has established a new technical benchmark. The IWC Pilot's Watch Mark XX series RW1 continues the essence of the Mark series, featuring a 40mm stainless steel case, a screw-down crown, and enhanced waterproof performance, upgraded from 60 meters to 100 meters for increased practicality. The dial retains its rhodium-plated hands coated with luminous material, iconic white hour markers, and the triangular marker at the 12 o'clock position. The color options include a sunburst blue, green, and matte black dial.The most significant change in the Mark XX compared to its predecessor is the upgraded 32111 in-house movement, developed and replicated from scratch without compromise. It also includes many high-end features, such as sapphire crystal glass, Italian calfskin leather, and a one-click detachable strap buckle. We invite you to appreciate the exquisite S1 recommended men's mechanical watch.
