Movement
Calibre SV-6 with 122-year moonphase. Automatic, 72 hours of power reserve, regulated in five positions before it leaves the workshop.
Case
Graphite-finished steel. 39 mm across and 10.6 mm deep, in stainless steel, with anti-reflective sapphire front and back. Water resistant to 50 m.
Dial
Applied indices with hand-polished flanks, luminous fill on the hour markers and a chapter ring printed in a single pass. The moon takes 29 days, 12 hours, 44 minutes and 2.9 seconds. A 135-tooth wheel gets close enough that the error becomes someone else's problem, in another century.
Strap
Black calfskin. Quick-release spring bars allow the strap to be changed without tools; every alternative strap in the collection fits this case.
