1970's Omega Seamaster Automatic Chronograph 176.007

This Omega Seamaster ref. ST 176.007 has an undeniable 1970s vibe, both inside and out. The funk is loud and clear due to the tonneau-shaped steel case, the beautiful blue dial, and the use of Omega's first automatic chronograph movement, caliber 1040.

The ref. ST176.007 replaced the preceding ref. ST 176.001 in 1972 and remained in production until around 1976, a fairly short run. The reference was offered in a stainless steel case, a gold-plated case, or a full 18k gold case. The steel version was offered in two dial color variations, in blue and silver, while the gold-plated and full gold versions were offered in gold or brown dials. The case was produced by case manufacturer Ervin Piquerez SA (aka EPSA), famous for their water-tight dive watch cases issued to many Swiss watchmakers, including Jaeger-LeCoultre, Longines, and countless other prominent Swiss watch firms.

What's interesting is that some of the the Seamasters and the Speedmasters were fitted with the Omega caliber 1040, which was the brand's first automatic chronograph movement. This workhorse movement was based on a movement produced by Lemania (caliber 1340), originally developed by Raoul-Henri Erard. The copper-colored movement had a frequency of 28,800 vph and came with a date and a 24-hour indicator.
