Introducing the Omega 30mm Caliber, made in 1960 .

 The " 30mm caliber" is touted as Omega's legendary caliber.
30mm refers to the diameter of the movement, and one of the regulations for chronometer competitions is that ``the diameter of the movement must be within 30mm .'' Since 30mm is the maximum size specified, Omega uses this size. We are hiring.

The 30mm caliber has achieved remarkable results, starting with its highest ever performance at the Kew Teddington Observatory Competition in 1940 , and going on to record good results at various observatory competitions.

The model equipped with a 30mm caliber has become one of Omega's best-selling and long-selling products, and is truly a legendary movement that still has many fans today.


The ``Omega 30mm caliber'' that we will introduce this time is a small seconds type that is especially popular among the 30mm series.
The second hand was installed at the 6 o'clock position, a specification often seen on watches up to the 1950s .

The addition of wedge indexes and floating Arabic numerals gives it an impressive classical appearance that is rarely seen on current watches.

Over 60 years, the color has become darker and the dial has become a pale beige.
The indexes have changed to a deep red copper color.

The classic look and beautifully aged colors combine to create an iconic watch that is truly vintage Omega.

The movement is hand-wound with 17 jewels and is equipped with Cal.268 .
In addition to high precision, the movement has a simple structure that provides stability, ease of maintenance, and durability.

The attention to detail can be seen everywhere in the appearance, with Omega's signature red gold plating, chamfered plates, and sunburst finish on the gears, all of which are made with the craftsmanship of the craftsmen of the time to make parts that are not normally visible look beautiful. It is a movement that makes you feel.


The size is length: 39.6mm , width: 34.6mm , thickness: 8.6mm , weight: 30g .
It's not too small and the thickness is controlled, so it's a size that is easy for anyone to wear.

It has a simple appearance, so just by changing the band you wear it, you can completely change the look.

Leather belts have a classic feel, so they go well with formal outfits such as suits and jackets.
Also, replacing it with a nylon belt gives it a more casual look, making it easy to incorporate into casual outfits such as shirts and cut-and-sews.

It's fun to wear nylon from spring to summer, and change the belt depending on the season from fall to winter to get a sense of the season.


Regarding the condition, it is in good condition overall.
There are some small scratches on the case, but the edges are still intact.
The dial has no corrosion or dirt and has aged beautifully.
The movement is also working without any problems.
It was replaced with a genuine Omega movement during the initial check.
