おすすめ〇〇選コミット銀座

Today we will be introducing luxury watch parts: "Movement" variations - Omega .

Luxury watch movements are made by hand by craftsmen combining hundreds of parts, and there are numerous variations, ranging from simple two-hand watches to ultra-complex mechanisms such as perpetual calendars and tourbillons.Moreover, they do not merely perform a specific function, but many are finished so beautifully that they are worthy of being called works of art, and many people are impressed by their beautiful form and consider purchasing one.

Therefore, over several posts, I would like to introduce the main movements of each brand along with their representative models.

This time, we will introduce the main movements used in " Omega ". Please enjoy until the end.

summary

What did you think.

We have introduced various wonderful movements, but when it comes to Omega, the name that always comes up as a masterpiece is the "Cal.321". The foundation of this masterpiece is the immeasurable presence of Lemania, but the technical capabilities of Omega, which has improved and created it, are remarkable. Why not take this opportunity to look for your favorite watch by focusing on movements that don't get much attention. Many of the representative models introduced this time have already been discontinued and cannot be purchased at authorized dealers, so if you are in the area, please stop by Commit Ginza.

Once again, we hope this article helps you find your favorite luxury watch.
