In 1947, Omega released to the world the first complicated watch featuring a moon phase readout it had ever built. Called the Omega Cosmic, it was extremely complex even in comparison to today's watches, and could display the month, date, and day of the week with moon phase. When set correctly, it could be used as a precision instrument or as a display of incredible workmanship purchased to adorn a deserving gentleman's wrist.

Today's offering showcases this beautiful and rare example of the 1st edition Cosmic, encased in 18K rose gold. This first edition example was made before the caliber change from 27DL to 381. 18K gold examples were the top of the line for this high-end line.

Its 18K rose gold is shapely with a great design. The back has one short crease and several pin prick indentions in the soft 18K gold. The top right lug has one discrete reinforcement not noticeable unless highly scrutinized or magnified. Otherwise the rest of the case presents in excellent condition with light remnants of wear. On the wrist it presents beautifully.

Its silver dial with its apertures for displaying the month, day, and phases of the moon is bright and clean. It was restored in vintage times and shows only light aging. Its subdials are original and untouched.

One of our Master Watchmakers who used to be the watchmaker for an authorized Rolex dealership and was given special training by Rolex at their Beverly Hills Service Center, has fully serviced its original complicated movement which consists of fully disassembling the movement down to the last screw, carefully inspecting each part, replacing any overly worn components, installing a new mainspring and stem, reassembling and lubricating the movement, and extensive timing testing and regulation (a $995 value).

It is running incredibly strong and true, keeping time on par with a brand new Omega in our testing position.

It comes equipped with a period correct Omega band and buckle making it ready for immediate enjoyment. We also stock lizard and a variety of others straps in various prints, skins, and colors if you'd prefer to keep the Omega band in nice condition. Please ask us if you're interested.

Accompanying the watch is its original Omega box.

Included with the purchase is a one-year international warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.

Note: An example of this model resides in the Omega Museum in Switzerland. A published example can be seen in Marco Richon's work, Omega: A Journey Through Time, 2007, pg. 471.

Complicated Omegas:
Usually when things are complicated, it means more stress, more work, and more effort, but in the end, it's worth it. The same holds true for vintage wristwatches, where gifted artisans and engineers from years gone by labored months and years to create complicated timepieces that transcend art and talent. When it comes to vintage wristwatches, the highest realms of respect and value are reserved for these watches that do much more than merely tell time.
