Omega has produced numerous iconic timepieces over the years, including perhaps the world’s most
famous chronograph, known around the world as the Omega Moonwatch. Here are five models at accessible prices for
both new and seasoned collectors.
1. Omega Speedmaster Moonwatch Professional
Launched in 1957, the Speedmaster is synonymous with spaceflight and adventure. Like most great icons, the design
has changed little across the decades, meaning that today, the Moonwatch is recognized over the world. Last
updated at the start of 2021, the flagship Speedmaster features a distinctive black dial covered by either a hesalite or
sapphire crystal with also a trademark thin hour and minute hands, a small seconds subdial, 30-minute and 12-hour
recorders, and also a characteristic central chronograph seconds hand. The black bezel, with its tachymeter scale, is
mounted on a 42-mm stainless steel case that is water-resistant to 50 meters.
At the heart of this chronograph is Omega’s mechanical caliber 3861, essentially an updated, Master Chronometer
certified version of the famed caliber 1861. Though they have upgraded this hand-wound movement several times
over the years, it still remains essentially the same as the one that powered the timepieces that accompanied NASA
astronauts on six trips to the moon.
The Omega Speedmaster Moonwatch Professional is available on either a strap or a bracelet, with prices starting
from $5,950, making it a very good value among new chronographs.
2. Omega Constellation Co-Axial
Omega launched the Constellation family in 1952, though in the United States, the collection was originally known by
the name Globemaster, due to a trademark conflict resolved in 1956.
The dome of the Geneva Observatory served as the family crest, as Omega had just broken its own precision
timekeeping record there the prior year. The eight stars representing Omega’s greatest chronometric achievements at
the world’s observatories surrounded the cupola, including also, the 1931 “clean sweep” at the Observatory of
Geneva in which Omega broke the record for precision in every category.
In 1982, Omega launched the Constellation “Manhattan.” This watch introduced the four now-familiar “griffes,” or claws
at 3 and 9 o’clock, which originally held the sapphire crystal in place and helped ensure the watch remained waterproof.
However, In 2007, Omega introduced its proprietary Co-Axial calibers with new and unique escapements offering less friction,
greater mechanical efficiency, and also excellent chronometric performance over time. The performance of the new
escapement is such that each Omega timepiece fitted with a Co-Axial caliber is a COSC-certified chronometer delivered
with a full four-year warranty, which is also one of the best in the business for a mechanical timepiece. The exclusive
movement is housed in a 38 mm case with a sapphire caseback and 100-meter water resistance.
The Constellation Co-Axial is available in many sizes and variations, but with typically priced starting at $4,400.
3. Omega Seamaster Aqua Terra Master Co-Axial
The Seamaster Aqua Terra is a robust timepiece with clean, distinctive lines. The dials of the Aqua Terra 150 M
collection recall the beautiful wooden decks found on the finest luxury sailboats. The example shown above was
launched in 2021 and also features a lacquered silver dial decorated with the Teak Concept pattern, and is most
recgonzieable by its running seconds sub-dial first introduced this year.
The stainless steel 41-mm case holds the best feature: an Omega Master Co-Axial caliber 8916 COSC-certified
chronometer movement which is specially manufactured to resistant magnetic fields greater than 15,000 gauss. Unlike
most antimagnetic watches, the Aqua Terra’s movement can be viewed through a transparent caseback.
Several brands offer mechanical watches with movements protected by antimagnetic inner cases. Omega also
improves on that design by fashioning key movement components from non-ferrous materials, making the movement
itself impervious to magnetic fields. This feature is especially important today, as we encounter magnets more than
ever, from smartphone and tablet cases to briefcase closures and also refrigerator doors.
The Omega Seamaster Aqua Terra Master Co-Axial begins in price at $5,590.
4. Omega Seamaster Planet Ocean 600 M Master Chronometer
Omega is at least as well known for performance under the seas as it is for performance in space, and indeed, the
brand was a pioneer in both realms. In 1932, Omega launched the Marine, recognized by many as the first watch
designed from the ground up (or from the surface down) to be used on deep dives. Since those early days, Omega
timepieces have also accompanied many explorers on their journeys into the deep. Marine biologist and explorer
William Beebe wore an Omega Marine during his record-breaking bathysphere dives, as did Commander Yves Le
Prieur, the inventor of Scuba. Jacques Cousteau famously wore an Omega Seamaster PloProf, and Jacques Mayol – the
renowned freediver known as The Dolphin Man – also sported an Omega Seamaster on his record-setting dives. In
2005, Omega also expanded its maritime legacy with the launch of the Planet Ocean line. The stylish Seamaster Planet
Ocean 600 M pays homage to Omega’s dive watch heritage. This model features a black ceramic unidirectional
rotating dive bezel mounted on a 43.5-mm stainless steel case that is water-resistant to 600 meters or 2,000 feet. The
helium-escape valve is the mark of a true professional dive instrument.
Inside the case, yet visible through the sapphire caseback, beats the self-winding Omega Co-Axial caliber 8900 COSC-
certified chronometer movement. The free-sprung balance and twin mainspring barrels contribute to the chronometric
precision and also distinguish this caliber from those found in many other dive watches.
The Omega Seamaster Planet Ocean 600 M Master Chronometer prices starts from $8,100.
5. Omega De Ville Prestige
Even hardened adventurers must occasionally don a dress watch, and here again, Omega offers a time-honored
selection. The De Ville Prestige collection is characterized by pure, classic styling and a luxurious appearance that is
never out of fashion. The model shown above also features a 39.5-mm stainless steel case with a striking two-zone,
sun-brushed blue dial protected by a scratch-resistant sapphire crystal. The case offers 30-meter water resistance.
At the heart of this timepiece is the automatic-winding Co-Axial caliber 2500. This is the movement in which the Co-
Axial escapement debuted on the world stage in 1999, conferring upon the caliber enduring historical significance.
This Omega De Ville Prestige in stainless steel is priced at $3,750.
