Part 1: The comprehensive list of Omega calibers, sorted

The beginning of the Omega’s story goes far back into the late 19th century and starts with a small shop in 1848 in a sub-alpine Swiss city named La Chaux-de-Fonds with a man named Louis Brandt. Today, Omega stands for one of the most recognized watch brands out there and one of the first associations on Olympic games. In our earlier blog posts, we’ve talked about the rich Omega history and its most famous re-presenters, such as the famous Moon watch and its adventurous colleagues, so now we want to explore the forces behind these wonderful timepieces.

When you start investigating the movements Omega has released under its name, you find that the number of them is incredibly large and it is pretty easy to lose your mind in all the references. Plus, there isn’t much information on some of the movements so the task of searching for it and consuming it is incredibly time-consuming, so we hope you’ll forgive us for the movements we don’t have much info on. Before anything else, we have to thank all the sources we found helpful in this try to build this comprehensive database on the Omega calibers. We also welcome any additional feedback or information so we can, hopefully, have them in one place one day, for all the Omega admirers and watch geeks out there. So, let’s dive into it.

Let’s first mention that not all Omega calibers were made in-house. Some of the calibers for Omega watches were manufactured by other manufacturers, mostly being the famous ETA and a historic Lemania (nowadays known as Manufacture Breguet), now both part of the Swatch Group, as Omega itself.

All Omega calibers can be split into several categories: Ebauche calibers, Quartz calibers, Electronic Calibers and In-House calibers.

Simply stated, Ebauche movements are those without escapements and mainsprings. They are also called raw movements, made for watch manufacturers, to build them into their watches. The Quartz revolution was a setback for such movements as they weren’t able to compete with cheaper, new calibers flooding the market. The remaining ebauche manufacturers that survived the Quartz revolution were mainly owned by the previously mentioned ETA.

Ebauche calibers can be further divided into Time-Only and Chronograph calibers. Below you can find the list of Omega Ebauche Time-Only calibers, with related calibers grouped together, along with the essential info on each of them, chronologically sorted:

The eighth and ninth decade of the past century brought what nowadays is called the Quartz revolution (sometimes related to as Quartz crisis). Basically, this is the rise of the quartz movements that started to replace mechanical movements all around the globe. The hit was largely taken by the Swiss mechanical industry that chose to stay with traditional mechanical watches, even though Asian watch manufacturers embraced the quartz technology. Still, Omega chose both, hence we have Omega quartz movements.
