About this entry

60% of key specs known. Missing: thickness, weight, hardening, crown, lume, bracelet offered.

Hour-and-minute moonphase watch, launched on Kickstarter in 2024 (The Calibrated Wrist, September 2024, then at a US$599 retail price). Brand specs, the same on all five dial pages: modified Miyota 9015 automatic, 316L steel, 39mm, 45.5mm lug-to-lug, 20mm lugs, 5 ATM, sapphire with inner AR (the Musou Black page says double AR coating), exhibition caseback with custom rotor, double lug holes. The moonphase only needs correcting every three years (brand). Thickness is left blank: Selten gives 11.4mm, The Calibrated Wrist 10.7mm, and neither says whether the crystal is included. The domed crystal is from the review. The Musou Black dial has no chapter ring. Selten notes that the hands were changed to gun-metal in October/November 2025 (Meteorite and the two mother-of-pearl dials). The watch ships on a leather strap; Selten sells an M1 bracelet separately (US$80, or US$150 with a tool-less micro-adjustable clasp; the H-link bracelet listing calls it On-The-Fly Micro Adjustment). All five dials were sold out on 2026-10-30, so the status is unknown.
