Crafted by the visionary Jiro Katayama in his Tokyo studio, the No. 6 is a masterclass in industrial brutalism and mechanical ingenuity. Courtesy of a module designed and built by Mr. Katayama, time is displayed by way of two steel hands which travel from left to right then retrograde back, the minute hand every 60 minutes, and the hour hand once every 12 hours. The date can be viewed in the small aperture at the 3:30 position.
The reverse side reveals the Miyota 9015 automatic winding caliber which beats at 4 Hz and delivers a power reserve of 40 hours. Sapphire crystals exist on both sides and the watch is pressure tested to 30 meters.
The Stainless Steel case measures 42.6mm x 11.8mm x 45.5mm lug-to-lug and is in unworn condition. Furnished on the OEM black calfskin strap with steel OL pin buckle. Complete with Box and Papers dated January 2026.
