I tried on the titanium edition a little while ago and it is a tour de force in mechanical watchmaking and surface finishing. In rose gold it certainly shines. Years ago I had the opportunity to see the original, outrageous Thierry Nataf Zero-G Defy, which was even designated as a tourbillon, which I believe it's not. Zenith have taken this outstanding movement concept and placed it within a beautifully designed and well proportioned timepiece. Regards, Baruch
