Omega Seamaster Chronograph Calibre .861

Omega Seamaster Chronograph Calibre .861

It is impossible to talk about high grade chronographs from the 1960s without bringing up the Omega Speedmaster.  In many ways, the Speedmaster set the bar for every sporting chrono that followed, raising the bar to a lofty new level (about 240,000 miles above Earth!).

But the iconic Speedmaster wasn't the only Omega chronograph made in the 1960s.  Their high grade manually wound Calibre .861, which supplanted the Lemania .321 in 1968 in Speedmaster line, also found its way into the considerably less common - one might even say rare - Seamaster chronographs from the same era. The Seamaster line was, at the time, the more stylish alternative - more about the looks than about its technical capabilities. But with the professional-grade Calibre .861 it was no less proficient a timing tool.

This particular piece is a truly beautiful example, highlighting the type of craftsmanship Omega was capable of at the time.  Featuring a stunning silver applied-logo dial, recessed pie-pan subsidiary registers, and silver stick markers set into a svelte polished 35mm steel case, this watch strikes a perfect balance between sport-timing tool and dress watch.  A rare find in this crisp condition!


Stainless Steel case is approximately 35mm (excluding crown). Omega Reference 145.018. Calibre .861 Manual Winding Chronograph Movement. Circa 1968.

Overall condition: Case is in excellent condition, professionally polished and stunning. Original applied logo dial is nearly flawless, with no loss of color or printing. Luminescent plots on dial and original hands shows light patination. Case back stamped "Waterproof". Original Omega signed crown and pushers.

Includes one 18mm brown Aristo leather strap and two nylon straps by Crown & Buckle.
