Makoto Boken 300M Titanium
Makoto is a Canadian microbrand, and the Boken, Japanese for adventure, is its Grade 5 titanium tool watch with a media-blasted case, 300 m of water resistance and a 60-click bidirectional ceramic bezel. The case is 40 mm across, 11.5 mm thick and 47 mm lug to lug, with a signed, lumed screw-down crown and a laser-etched screw-down titanium caseback. The indices are raised 3D lume blocks in BGW9, and the movement is the Miyota 90S5, the premium Miyota automatic. It comes on a quick-release FKM rubber strap with a laser-etched titanium buckle, in blue, orange or both. Makoto is making 75 of them for 2026, sold as a pre-order, with shipping due to start in October 2026.
