Omega 30T2 Ref. CK 2383

Winning Bid: $800.00

The History

Early wrist watch manufacturing was all about accuracy. Omega’s 1932 brand slogan read, “Omega – Exact time for life” and they meant it. The brand’s exceptional performance spoke for itself at the ever-important Geneva Observatory, exclusive to Geneva-based companies, and Neuenburg Observatory, open to global makers, competitions throughout the early 20th Century.

At the 1945 Geneva Observatory competition in a group specifically for wristwatch movements, Omega’s caliber 30 was awarded first prize against the likes of Patek Philippe and Rolex. At the time, this was a huge deal. Massive amounts of press and notoriety came to both the brand and the movement. Having been available for commercial purchase since 1939, Omega’s caliber 30 series of movements, on the tailwind of observatory victory, would come to be a backbone for the brand. Offspring of the same base caliber 30 remained in new Omega wristwatches until 1966.

A refined iteration of that same award-winning movement, the cal. 30T2 forms one of the most collectible groups of time-only watches in the world of vintage collecting. Many of these watches were sold and, more importantly, many references and variants were created by Omega— creating the perfect storm of accessibility and rarity.

The Reference

The Omega reference CK 2382 is the international case model of the CK 2400 Suveran made for the Swedish market. Side by side these two models are almost identical with the main difference being the case size. The CK2382 comes in at 35.5mm and the Suveran at 35mm. You can find these great Omega watches with various dial configurations. Some had roman numerals, some had chapter rings and some with black dials. The particular watch that we have here has a fantastic combination of a white egg shell dial with Arabic numerals.

The Case

The stainless steel case of this Omega measures 35.5mm and features a classic simple design with curved and drilled lugs. The case is in good condition having been polished at some point in the past and shows minimal scratches throughout. The signed crown is a later replacement as the original crown would have been unsigned. The case back is a six notch screw in design and bears no engravings on the outside and is also thought to be a later replacement part as it has the non-matching 2639-12 engraved on the inside.

The Dial and Hands

The dial and hands on this nearly 75 year old Omega tell a great story of the watches age and story. The face has developed a patina to somewhere between a white eggshell and silver that makes the lumed Arabic numerals extremely legible and gives the watch an overall military/field watch aesthetic. The hands are a classic syringe shape with the hour hand displaying full amber colored lume. Unfortunately, the minute hand has lost most of its lume and the lume on the numerals has eroded specifically on 1, 11, and 12. The watch also features a grooved small seconds dial at 6 o’clock.

The Movement

The caliber 30T2 is a highlight of this piece and a historically significant movement in its own right. The 17 jewel movement was heralded in its day for its precision and is still praised by collectors for the same reason today. The movement serial number is in the 13 million range which places its production in 1952. The watch is running and keeping good time but the service history is unknown.

The watch comes on a non-original leather strap with non-original buckle.

    I put a Geiger on it today and it came back as real radium lume

    This watch is so clean and simple. The 1950’s design from Omega is exactly what vintage watches should be. Classic piece!

    • richfordon

      Agreed with Jaden’sAP! Couple this classic design with the provenance of the movement, what more could you need out of a vintage time only?
