About this entry
73% of key specs known. Missing: weight, hardening, AR coating, crown.
Limited production released in September 2023 (ordering opened 8 Sep 2023) and sold out; the brand says it will not be repeated, but no edition size is stated. GPHG 2023 "Challenge" finalist. "True GMT" Miyota 9075: the local hour hand jumps in one-hour steps with the date following. Bidirectional bezel with lacquer-filled 24-hour markers is deliberately clickless (friction). Case 9.8mm without the box sapphire, 11.7mm with it. Water resistance 5 ATM. The release page no longer shows a price; the $2,250 launch price is from Worn & Wound's launch article. Lume is only stated for the red 24-hour hand. Crown type, caseback, AR coating and weight not stated. Sold on a calf leather strap only (no bracelet listed).
