If I’m not mistaken , correct me if I’m wrong, it’s the one from WatchMaxx in the USA. Congratulations of joining the Calibre 16 team. When I first saw it a couple of days ago, I said to myself “that won’t be around for long” and i was completely right. Having just bought a Heuer 01 carrera I am totally poor again. Enjoy the watch head, if it’s anything like mine for accuracy you will be shocked in a good way.
