Hi SJX,

The Breguet Tradition tourbillon does not have a constant force escapement.  Perhaps Suitbert or someone could clarify the distinction, but a fusee is different from either a constant force escapement or a remontoire.

Also, the De Bethune DB24 does not appear to have a variable inertia rotor, but rather a variable efficiency automatic winding system.  It's not clear from the picture how it works exactly (switching from bi-directional to uni-directional?), but it's not possible to adjust the inertia of the rotor via the winding crown.  I'd love to learn more about it however.

Lastly, in the Moser Strauman double hairspring balance assembly, both hairsprings are flat rather than having Breguet overcoils.

Ok, those are all the nits I have to pick.  Thanks again for the great report and pics!  Do you happen to have a wallpaper sized (1024x768) version of the 1st Tradition tourbillon pic? smile

Very comprehensive report on the watchmakers covered -

thank you Jia Xian - and, of course, the kind sponsor Peter Speake-Marin. Just out of idle curiousity - what made you choose the watchmakers you covered? Cheers, Dirk

The main consideration was whether the brands have forums here. That accounts for nearly all the brands. The rest, like Moser and De Bethune, were unplanned. I just happened to get the opportunity, but I am glad I did, especially in the case of De Bethune... 

Thanks (nt) [nt]
