the 1st an only photos of the new Cal 1120

Vacheron Constantin is coming out with a new version of its iconic caliber 1120: the rotor is redisigned and now elegantly skeletonised but the good news is that's its being presented in its original gorm with a Gyromax balance!

it looks to have been done very well.  Thanks VC for giving it back it's Gyromax!  Love the Maltese Cross in the rotor. Besides the Historiques 1968, I'm looking forward to seeing other watches that will uilize cal K1120. Congratulations VC on all the true High Horology pieces that were introduced, the cal 2253, cal 2755 and others are unbelievable works of craftsmenship and art - unfortunately all are too expensive for my tastes, but one can always admire from afar.

Thank you Alex and welcome back to K1120 in its original configuration I hope we can see as soon K1121 with this wonderful new rotor, possibly behind a sapphire caseback

The new 1120 is freesprung gyromax?
Yes, that is my understanding of the new cal 1120

The original cal 1120 also used a freesprung Gyromax balance (licensed from Patek?).  I have a 1975 Extra-Flat with a freesprung cal. 1120.  At some point in time, VC decided to get away from using the Gyromax and installed a micrometric adjustment system in the 1120.  I don't really know why.

Are ruby rollers still used to support the rotor?

I don't seem to be able to find them in these pictures, I thought it might be easier to see with a relatively "skeletonized" rotor.  BR, Dan

The four ruby rollers are under the beryllium ring which is affixed to the rotor weight - the rotor and ring turn as a unit!  You can just see one of the mounting plates above the serial number in this picture:
A HA, Thanks Dean! (nt)
