General Description:
H dials follow traditional Speedmaster design. Matte black with painted lume, painted logo, open date window. Dials are all professional with the word “AUTOMATIC” at 3:00. Dial H1 is likely the only Mark IV dial that is original to reference 176.009. Dial H2 is a later service dial that is notable for the use of blue on the 24 hour subdial at 9:00. As such, dial H2 is uncommon and usually found on watches that received full overhauls and refinishes from Omega/Swatch Group.
