The Omega Speedmaster Professional 311.30.42.30.01.001 is the standard-production
stainless steel Moonwatch reference that anchored the third-generation pre-2021 
Speedmaster Professional lineage, carrying the Hesalite crystal and the manual-wind
Caliber 1861 that powered the Moonwatch from 1996 through the 2021 Caliber 3861 
transition. The Speedmaster Professional Moonwatch lineage itself traces to 1965,
when NASA flight-qualified the Speedmaster for all manned space missions following
the 1962 acquisition of the model by Wally Schirra for his personal use aboard Mercury-
Atlas 8. The 42mm stainless steel asymmetric case carries the polished sloping bezel
with the engraved tachymeter scale, the twisted lugs, and the screw-down crown that
have remained unchanged across more than five decades of Moonwatch production. The
matte black step dial features applied luminous indices, broad luminous baton hands,
and the three classic Moonwatch sub-counters arranged with the 30-minute counter
at 3, 12-hour counter at 6, and running seconds at 9. Powered by the Omega Caliber
1861 manual-wind chronograph movement, derived from the Lemania 1873 base, beating
at 21,600 vibrations per hour with a 45-hour power reserve. Sapphire crystal caseback,
water resistance to 50 meters. Pre-owned.
