We would like to introduce you to watches from OMEGA, a Swiss watch manufacturer founded in 1848.

This is the 1966 model of Omega's signature automatic model, the Constellation.
The gold-colored case features a black dial and gold indexes, creating a stylish and luxurious look.
It is equipped with the "CAL561" with date function from Omega's heyday, and is a chronometer movement with a swan-neck type regulator fine adjustment device.
It was just overhauled in March 2025, so it is in good working condition.

We hope this once-in-a-lifetime encounter will be a special one for you!
