Omega Speedmaster Mark IV 4.5 Chronograph Ref 176.0012

Specialized watch enthusiasts are cognizant of the extensive array of references within the Speedmaster family.

Throughout the iconic watch’s extensive production history, the “Mark” series of Speedies has coexisted alongside the conventional “Moonwatch” variant. The inaugural Mark II was introduced in 1969, followed by subsequent versions bearing similar nomenclature in 1971, 1973, and 1984. Each iteration incorporates a tonneau-shaped case and a prominent tachymeter chapter ring. Consequently, the Speedie 176.0012, which exhibits these characteristics, presents a unique anomaly. Not officially designated as a “Mark” version, it has garnered the distinction of being regarded by collectors as the “Mark 4.5”; an unofficial member of the exclusive “Mark” club. It incorporates the Mark IV case and the Mark V movement, rendering today’s timepiece a formidable tool watch capable of active engagement. The dial is replete with the invaluable chronograph features that have contributed to the Speedmaster’s renowned reputation.

Concluding this watch’s illustrious legacy, it stands as one of only a select few Speedmasters that harmoniously combine the Speedie design with the Lemania 5100 movement—an engine utilized in the Speedmaster “Holy Grail” 376.0822.
