One of my discoveries from the Time to Watches exhibition currently being held in Geneva is the Italian Brand OISA (Orologeria Italiana SocietΓ  Azionaria) 1937.











They make their own movement in-house such as the OISA 29-50 caliber, Ref. OM-PU/60, which can be fully customized based on your request such as decorations on the bridges and plates: perlage, anglage, and Côte de Genève. Also various galvanic treatments, including nickel, rhodium, ruthenium, and NAC. Laser engraving available upon request.

















Here is an excellent article on Monochrome about an OISA 1937 and a Collector's Journey.

One of the Coolest things for me is that OISA 1937 offers an OISA Lab experience where you can learn to make a movement and even assemble a watch.





This is now the third course I am aware of after the Hampden Watches course in Chicago and the Paul Gerber Uhrenkurs.

You can see more about that in this post

It is great to see a full Italian Watch Manufacture and find their Art Deco logo charming.
