We apply repeated processes of pressing, cutting, and polishing to make a stainless steel case back that is smooth on the wrist but protrudes upward in an intricate, 3D form. Its configuration interlocks with the top bezel, with uniquely shaped screws joining the two. With its stunning Sallaz-polished surfaces and intricate beauty of form, this timepiece shows off the profound look of the metal material itself, while also achieving a slim profile.

While maintaining shock resistance, we optimized the circuit board layout by using smaller, slimmer parts and integrating electronic componentry with high-density mounting technology. This multi-hand chronograph is equipped with Smartphone Link and solar-powered radio control, but with a module 1.45 mm slimmer than the MTGB1000. That makes the watch more than 2 mm slimmer, at just 12.1 mm.
