About the Omega Speedmaster Collection

Be it the first space watch or the first chronograph under the brand, the Omega Speedmaster collection holds various distinctions under its belt. Launched in 1957, it was originally designed as a chronograph for racing and sports but it soon found its place in history through its association with NASA. By 1965, the Speedmaster had passed rigorous testing and was officially "Flight Qualified for All Manned Space Missions." This certification led to its selection as the official watch for NASA astronauts, including during the Apollo 11 mission in 1969, when it became the first watch worn on the moon and remains the only watch certified by NASA for all manned space missions.

ABOUT THE MOVEMENT

Calibre 3861 was introduced in 2019 with the Speedmaster Apollo 11 50th Anniversary Limited Edition and has since powered many celebrated Speedmaster models, including the Speedmaster Snoopy. It replaces Omega's revered calibre 1861, bringing some modern advancements while retaining many elements of the predecessor. Case in point, calibre 3861 also works with a hand-wound mechanism and boasts a cam-actuated chronograph function with a horizontal clutch. Further, the construction includes 26 jewels, a co-axial escapement, and a silicon hairspring. Subsequently, the movement provides 15,000-gauss magnetic resistance, making it METAS-certified. Beating at 21,600 vibrations/hour, calibre 3861 promises a power reserve of 50 hours and an accuracy of 0/+5 seconds/day. Most components are rhodium-plated, and there are Geneva stripes on the bridges, fine polishing on the bevels, and circular graining on the main plate. Overall, it is a well-decorated Master Chronometer movement.
