On the prime of the roster is a mechanical restricted version, which is available in a chrome steel, 38.5mm x 16.7mm case and which is powered by a Sellita caliber SW-510BHb computerized chronograph motion; it is a two-register chronograph motion with small seconds at 9:00 and a central seconds chronograph hand. It is solely very barely bigger, it appears like, than the unique. (I have never had an opportunity to measure this actual mannequin in individual, however the Deep Sea 666 Chronograph B was 37mm x 15mm.) The unique, like the brand new model, had working seconds at 9:00, a central chrono seconds hand, and a 30-minute register at three:00.
