Introducing the Omega Seamaster in the 1960s .

 The Seamaster, which is synonymous with waterproof self-winding watches, is one of Omega's representative models.
Since its announcement in 1948 , it has received high support from people all over the world, and even today, various types of models have been released.

There are various types of vintage Seamasters, such as the type of case and dial, and even if there is a solid body with the same specifications, it is a watch that is more prone to individual differences than other watches due to the way it ages.

The Seamaster itself is a vintage watch that is easy to obtain, but if you find one with specifications you like or an individual that has undergone aging, you may not be able to obtain it again, so be sure to check it out.


The Seamaster introduced this time has rare specifications everywhere.
When it comes to waterproof watches, it is common to use a screw-back type that is attached by turning it like a screw, but this one uses a snap-back type back cover that is inserted and used.
In addition, Seamaster's trademark hippocampus mark is also engraved larger than usual.

In addition, because the lugs are thick, it is finished with a rare ranchero case specification.


Next, looking at the dial, you can see many dials with brighter tones, but on the contrary, the silver color has changed to a darker, deeper shade, which emphasizes the reflection of the sunray finish. By being done, it becomes a dull and heavy color. It is an individual that has undergone a special aging with a very astringent taste.

It is a unique solid with rare features such as case specifications and dial aging.

The installed movement is Cal.501 . 20 -jewel self-winding model.
This movement is an enlarged version of Omega's first full-rotation self-winding Cal.470 .
It is a movement that has a good reputation in terms of operability, maintainability, and accuracy.


The size is length: 43,4mm (including lugs), width: 37,7mm (including crown), thickness: 12mm .
The size is very easy to wear, and the thickness is 12mm , so it has a moderate volume.

There are minor scratches on the case, but there is no problem with the dial and movement.
Comes with genuine bracelet.


Seamaster with rare specifications can be seen everywhere.
It has a simple yet heavy presence, and is equipped with a highly versatile original bracelet, making it suitable for all occasions, from business to casual.
