Omega Replica kicked off the year 2021 with a bang by elevating the legendary Moonwatch to Master Chronometer. Although this watch is equipped with the latest movement technology, detailed observations in our test find that its exterior remains true to the design of the cult model.

Affectionately nicknamed the “Moonwatch” because it accompanied astronauts who landed on the moon, this Speedmaster has become a cult watch that is always only gently revised.

While Omega Replica announced that it wanted to exclude the Moonwatch from the first Master Chronometer certification more than six years ago, the manufacturer now presents the next generation of models. There are a now total of eight new versions in stainless steel and Omega’s proprietary precious metals (Sedna red gold and Canopus white gold), either with a historically inspired Hesalite crystal or a contemporary sapphire crystal, with a closed metal back or a transparent sapphire crystal in the back, attached to a leather, nylon or metal strap, and each with a five-year warranty.

Whichever Moonwatch you choose — a lower-priced model like our test watch with Hesalite crystal, closed back and stainless-steel bracelet for $6,300 or the most expensive version in 18k Canopus white gold for $45,300 — you always wear a piece of authenticity on your wrist. Omega’s President and CEO Raynald Aeschlimann explained, “When you redesign a cult watch like the Speedmaster Moonwatch, every detail must remain true to the original spirit of the timepiece. This chronograph is known around the world, so we approached its design with great respect, while at the same time elevating the movement to the next level of watchmaking.”

Omega plans to certify all of its new watches in 2023 as Master Chronometers. Today, 99.99 percent of its watches already earn this distinction. And Omega accomplishes this with an annual production of between 600,000 and 700,000 watches.

The Moonwatch is also offered in Sedna gold (right) and Canopus gold (left).

The Moonwatch Master Chronometer Pays Tribute to the Past
Omega definitely shows respect for the past. The current Speedmaster Moonwatch Professional Co-Axial Master Chronometer Chronograph 42 mm, as this timepiece is known by its full name, is inspired by the fourth generation of the Moonwatch, which was worn by the astronauts of the Apollo 11 mission when they flew to the moon in 1969. Insiders often refer to this model as Ref. ST 105.012.

Ref. ST 105.012 and Ref. ST 145.012 have asymmetrical cases because of their crown protectors. This protection was added after NASA saw a danger due to the possibility of inadvertently adjusting the crown and thus the time display. Ref. ST 105.012 and Ref. ST 145.012 are the officially certified models and have had the word “Professional” on their dials since 1966. Before that, this lettering had previously adorned only a few examples of Ref. ST 105.003. Buzz Aldrin is said to have worn an ST 105.012 when he stepped onto the lunar surface, while Michael Collins kept an ST 145.012 strapped to his wrist as he waited inside the capsule.

Be that as it may, our test watch (Ref. 310.30.42.50.01.001) has the same classic asymmetrical case, which provides reliable protection against shocks and accidental operation with the combination of historically correct hat-shaped pushers and a knurled crown on its right side. The crown is quite heavy and difficult to grasp because of its flank protection. And it takes quite a few possibly arduous rotations of the crown to replenish the full 50-hour power reserve of hand-wound Caliber 3861.

Nevertheless, manual winding is a popular ritual among watch enthusiasts, as is evident in increase in the number of hand-wound fake watches available on the today’s market. If you forget to wind this watch for more than two consecutive days, you’ll also need to manually adjust its hands. But this task is easily accomplished by slipping a fingernail under the crown, and gently lifting it into its outer position. The crown has no middle position because the Moonwatch lacks a date display. Instead, Caliber 3861 provides a stop-seconds function to facilitate accurate time setting. To-the-second setting really makes sense here because this watch runs no less reliably than the phases of the moon. As a Master Chronometer, it deviates from perfect timekeeping by only 1 second per day in all situations — whether fully wound, with its chronograph running or not running, and on or off the wrist. Also noteworthy are the small rate differences among the individual positions and the stable amplitudes, both when the power reserve is decreasing and in each of the several positions.

The historical legacy of the Moonwatch includes a Hesalite crystal and an aluminum bezel with tachymeter scale.

The chronograph’s pushers are pleasant to use, with pressure points that feel surprisingly even and a make a very secure impression both haptically and audibly.

When you start the chronograph, the slender elapsed-seconds hand with its arrow-shaped luminous tip is also set in motion. Six subdivisions per second correctly match the movement’s frequency of 21,600 vibrations per hour. Caliber 3861 was adapted from and is essentially based on the historical Caliber 861. Omega also gets the subdivisions on the stop-seconds scale absolutely right, with two subdividing strokes for three hertz. These tidy strokes are arranged along the outer rim of the so-called “step dial,” which is slightly elevated in the middle, where three subdials are positioned in the classic tricompax arrangement. These details combine to create a harmonious picture with historical authenticity that’s further affirmed by the high curve along the rim of the Hesalite crystal.
Hesalite rather than sapphire for the crystal is the most authentic allusion to the Moonwatch’s heritage, but Hesalite scratches readily, as also became apparent in our wearing test on the wrist. If you don’t like its susceptibility to scratches, you can opt for a sapphire crystal and, in this combination, a second sapphire crystal in the caseback. The double sapphire model then costs you $7,150 with a stainless-steel bracelet or $6,800 with a leather strap.

The finely crafted stainless-steel bracelet ends in a folding clasp with Omega’s logo and a historically authentic color scheme.

The Master Chronometer Caliber Refers to the Historical Movement
In keeping with its ancestor, the double beveled screw-in back is closed on our test watch with a Hesalite crystal above the dial. Various engravings and inscriptions refer to historical events as well as to the inner workings of Caliber 3861.

Omega worked for more than four years on this caliber, which premiered in spring 2019. The starting point for its development was Caliber 861, which had been built since 1968 on the basis of Lemania’s Caliber 1873. This mechanical chronograph had a frequency of 21,600 vibrations per hour and included counters for 30 elapsed minutes and 12 elapsed hours, cam switching and horizontal gear coupling. In addition to all these features, Caliber 3861 also preserved Caliber 861’s dimensions of 27 mm in diameter and 6.87 mm in height.

The one-sided deployant clasp with polished Omega logo is also satin finished and is designed to be reminiscent of earlier Moonwatch models. A small but quite important detail for enthusiasts and collectors is the “dot over 90,” the point about the 90 that was on the side of the dial in some previous models as well as the dot at the 70, which is now diagonally below the 70 on the anodized aluminum bezel. These model-defining details continue to write history with the legendary Moonwatch, even if they are, quite rightly, ticking with a modern movement.
