Introduced in 1971, the Mark III represents an important evolution of the Speedmaster line and was among the earliest automatic chronographs produced by Omega.\u003c\/p\u003e\n\n\u003cp\u003eThe watch features the distinctive tonneau-shaped stainless steel case design typical of early 1970s Omega sports watches. Its bold lugless case profile curves naturally around the wrist and reflects the futuristic design language of the period.\u003c\/p\u003e\n\n\u003cp\u003eThis model is powered by the original Omega caliber 1040 automatic chronograph movement, based on the Lemania 1340 architecture. The movement contains 22 jewels and features a central chronograph seconds hand and central chronograph minute hand, a 12-hour counter at 6 o’clock, a small seconds subdial combined with a 24-hour indicator at 9 o’clock, and a date display at 3 o’clock. The movement beats at 28,800 vibrations per hour and offers an approximate power reserve of 44 hours.\u003c\/p\u003e\n\n\u003cp\u003eThe sunburst blue dial features applied hour markers, luminous hands and indexes, and a contrasting chronograph minute hand with a distinctive orange “jet” shaped tip. The outer dial ring includes a tachymeter scale with a detailed minute track, reinforcing the Speedmaster’s motorsport heritage.\u003c\/p\u003e\n\n\u003cp\u003eThe watch is housed in a 42mm stainless steel tonneau case with pump chronograph pushers, a signed Omega crown, and a screw-down case back featuring the iconic Omega hippocampus medallion.
