About the Item

OMEGA Speedmaster Professional Mark II – Ref. 145.014 – Calibre 861 – Circa 1970 Introduced in 1969, the Speedmaster Mark II represented Omega's first major evolution of the legendary Moonwatch. Retaining the same professional chronograph spirit while embracing the bold design language of the early 1970s, it remains one of the most distinctive references in the Speedmaster family. This example is powered by the renowned Omega calibre 861, derived from the Lemania 1873 and identical to the movement fitted to post-1968 Moonwatch models. Celebrated for its reliability and robustness, the calibre 861 became one of Omega's most successful chronograph movements. The brushed stainless steel monobloc tonneau-shaped case offers a strong wrist presence and excellent ergonomics. The original matte black dial features the classic tri-compax layout with evenly aged tritium hands and hour markers. The tachymeter scale is integrated beneath the crystal, a characteristic innovation of the Mark II generation that improved both legibility and protection. The watch was fully serviced in September 2025, including a complete chronograph overhaul, cleaning, regulation and replacement of the Omega tachymeter crystal. The original crystal has been preserved and accompanies the watch. A very light polish was performed while respecting the original brushed surfaces. Fitted with its original Omega stainless steel bracelet and signed clasp, the watch is running accurately and is ready to wear.
