speedmaster alaska project - limited full set edition

The Omega Alaska Project Chronograph is a Speedmaster designed by NASA and Omega engineers to operate safely in extremely low temperatures. A prototype model from the 1960s, produced in only a few examples, it inspired the design of the Speedmaster MK II.

In 1970, Omega released the Alaska Project II, using the Moonwatch case design and all the key features of the original prototype. The watch came in a special box with various accessories, including the iconic red outer case with oversized pushers designed to operate the chronograph function while wearing thick gloves in extreme cold. Included with this ultra-rare collector's timepiece are several straps, including one of the “Deep-Cold” type. Designed to withstand temperatures close to absolute zero, this unique Moonwatch is also the ideal tool for expeditions in extreme climates. In 2008, to commemorate the 40th anniversary of the original project, Omega released a limited edition series of 1,970 pieces.

This extremely rare Full-Set watch is delivered with its original box, papers, and all accessories. White dial, high-visibility “black rocket”-style hands for the subdials, and Flightmaster-style hands for the hour and minute hands. With its high-contrast white dial designed for visibility in low light, this collector’s piece offers an excellent alternative to the Rolex Explorer II for extreme exploration. Originally developed to assist astronauts during extravehicular activity in space, its red outer case is built to withstand a temperature range from -146°C to +260°C. This model is regularly worn by experts exploring volcanoes or polar regions.

Hand-wound mechanical movement, Omega Caliber 1861. To protect it from shocks and temperature changes, the watch features a “Delrin” brake, a material that shields it from magnetic fields, humidity, solvents, and chemicals. This material also raises the melting point, improves rigidity, and enhances dimensional stability. Starting in 1994, Omega replaced gold finishing with rhodium to reduce movement weight, and added a jewel to the chronograph wheel, bringing the jewel count to 18 — allowing for continuous chronograph use without damaging the movement.
The movement beats at 21,600 vibrations per hour, or 6 ticks per second on the central “Flat Second” hand. Based on the Lemania 1873, it offers a hacking function for precise time setting by turning the hands counterclockwise. It is equipped with a flat “Glucydur” balance spring.
The three-register chronograph operates in “Stop & Go” mode with auxiliary counters displaying elapsed time up to 12 hours, 59 minutes, and 59 seconds. The left register shows running seconds, the right one tracks 30-minute intervals, and the bottom one is a 12-hour totalizer. The movement starts functioning with the first crown turn and offers a 42-hour power reserve after full winding (approx. 20 turns).

Given the very limited production run, the originality, exceptional condition, and complete set status of this timepiece greatly enhance its appeal for collectors.
