1972 Omega Seamaster Chronograph 176.007 Gloss Blue Dial

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.

Founded in 1848 by Louis Brandt in Switzerland, Omega has grown into one of the most respected and innovative names in watchmaking. The brand’s early focus on precision earned it accolades at international observatories and competitions, setting the stage for decades of horological achievement. Omega became the official timekeeper for the Olympic Games in 1932, and in 1969, the Speedmaster Professional—nicknamed the "Moonwatch"—made history as the first watch worn on the lunar surface during NASA’s Apollo 11 mission. Omega’s innovations continued with the introduction of the Co-Axial escapement in the late 1990s, a groundbreaking movement that dramatically reduced friction and improved long-term accuracy.

Omega’s lineup showcases a wide range of iconic models that reflect the brand’s legacy and versatility. The Seamaster, introduced in 1948, is a favorite among divers and famously worn by James Bond since 1995’s GoldenEye, blending technical capability with cinematic cool. The Speedmaster remains one of the most storied chronographs in existence, while the Constellation is known for its refined design and chronometric precision. The De Ville collection offers a more elegant, dress-focused aesthetic, often featuring high-end complications and meticulous finishing. Omega continues to lead with innovations like Master Chronometer certification, METAS testing, and antimagnetic technology—ensuring that its watches are not just beautiful, but built for the demands of modern life.
