Omega Speedmaster Mark IV reference 176.009 from 1977

Description What distinguishes the Mark IV isn’t just its technical depth but its distinct visual language. The stainless steel case, often described as a cushion or tonneau shape, departs from traditional round silhouettes with a wide, sculpted form that hugs the wrist. Measuring approximately 42mm across with integrated lugs, it wears with presence and solidity, embodying the unapologetic styling of the era. Paired here with a supple leather strap, the watch takes on a slightly more restrained, vintage elegance that contrasts beautifully with its otherwise technical design. The black dial balances complexity and clarity, featuring a central chronograph layout with running seconds and a 24-hour indicator at 9 o’clock, 12-hour totalizer at 6, and a date window subtly integrated at 3. These elements, set against a matte black backdrop with white accents, are anchored by a fixed tachymeter bezel under the crystal — a visual hallmark of the Speedmaster family, reinterpreted here in a more modern, enclosed form. At the heart of the watch lies Omega’s Calibre 1040 — the brand’s first automatic chronograph movement, based on the robust Lemania 1340. It delivers smooth timing and a technically impressive suite of complications. The 1040 was a statement: that automatic chronographs were not just a novelty but a future-proof evolution of the mechanical watch. The 176.009 Mark IV wasn’t made in large quantities, and today, finding one in original condition — especially with a clean dial, functioning chronograph, and sharp case geometry — is increasingly rare. This 1977 example captures the innovation and design courage of Omega in the post-space-race era: a time when the brand wasn’t resting on lunar laurels, but rather experimenting with what the next generation of Speedmasters could be. This isn’t just a chronograph. It’s a 1970s artefact with substance — a watch for collectors who appreciate when form and function push the boundaries of tradition. What we love: Beautiful case All period correct Funky watch What you should know: Unless otherwise stated, it is common for vintage watches to not come with box and papers. In the rare example that a watch does come with box and papers it will be mentioned in the description. All purchases come with a bespoke black wooden watch box and warranty card.
