Girard Perregaux

In 2013, Girard Perregaux released the Constant Escapement which offers linear energy to the balance wheel thanks to an ultra thick ( 14 microns ) silicium blade buckling back and forth. The interest being that the amplitude is never the same all along it...  

The size is daunting, but I am very interested in it. I like seeing the design lineage from the Rolex project; that is very cool. What I do wonder is just how well the mechanism performs and is designed. I read somewhere that someone on the forum had an i... 

But I don't get the point of mechanical innovation when it isn't implemented in a way that makes the watch wearable. Even as an engineer and a tech enthusiast I can say that watches first have to be wearable and beautiful, then comes the rest, at least fo... 

Very fascinating project and a pity it did not spread more. At the time they thought every manufacturer would rush to license it

For those who dont know CSEM it was originally created many decades ago as a consortium of Switzerland’s biggest corporates and it focused (at the time) on microelectronics. They developed the original/first ever quartz movement which was used later by Ro... 

The videos of this watch on YouTube are mesmerising. As you say, it’s a shame it’s not a little bit smaller but no doubt that will come in time. All the best, Jon

I like it a lot. The size is not a problem for me. The thickness is just ok. 👍

Visually this last iteration is my favourite! Stunning

GP force constante escapement?

I like ingenuity, just on too big of a scale here IMO.

Pushing the boundaries of what is scientifically conceivable within an outdated technology. How not to be enthralled?

Aesthetically than the original ones But I reserve judgement till one day I can actually handle it in the metal Nonetheless it’s a pure beauty and true tour de force

This and the Neo Bridges (unsurprisingly) are my favorite GPs. The latest version is definitely my favorite here. Would love to experience it firsthand. Thanks for the excellent images, Filip

It certainly shows of what GP is capable !!
