Comparing some Vacheron Constantin Tourbillon calibers

 

The idea of this thread came to my mind while comparing the newly released caliber 2162 QP/270 powering the Traditionnelle Tourbillon Perpetual Calendar (ref. 6300T/000P-H056) with what is considered to be Vacheron's first Tourbillon caliber for a wristwatch: caliber 1760, created to power the ref. 30050.

And, for me, this very first caliber is hands down the most good-looking of the whole range...

Judge by yourself.

Best, Emmanuel


A/ CALIBER 1760 (manual winding with power reserve indication)

This caliber was developed around 1990 in collaboration with the Nouvelle Lémania movements factory for Vacheron Constantin's first wristwatch with a tourbillon: the ref. 30050, shown below, which was produced as a limited edition of 300 pieces, 160 in yellow gold and 140 in platinum.

2/ Ref. 30051/000R-8002 (skeletonized version of the previous model: the caliber should be referenced as 1760 SQ, but doesn't seem to have a specific "name")

B/ CALIBERS 1790 & 2795 (both manual winding and same overall architecture, but the 1790 has power reserve and date, whereas the 2795 is tourbillon only and bears the Geneva Seal)
