MORE FROM THEOREMA

Morning y'all Is this actually German engineering? Let’s look closer at the Theorema GM-103 Mechanical. ​While the dial and the case back proudly claim "Made in Germany," the skeletonized heart beating inside is actually an adjusted Chinese movement (a Hangzhou/Sea-Gull variant). Thanks to European assembly laws, final QC and casing in Germany allow for the label—making it a classic "Germasian" timepiece. ​It looks stunning and complex, but what are your thoughts on brands doing this? Let’s talk in the comments! ​Subscribe to @arbalexwatches for honest watch breakdowns! #Theorema #SkeletonWatch #GermanWatches #MechanicalWatch

The beauty of a see-through movement... is the sound. The details. The fact that someone carved metal into art, just so it could tell you the hour. But I don’t think about wearing it. I think about watching it breathe.

Theorema CasaBlanca GM 101-3. It's undeniably beautiful. Full skeleton. Made in Germany. This is one of those watches you love or you hate and I absolutely love it. It's even more special because I did the restoration and also made the strap! Happy Xmas everyone!
