The case is 44 mm in diameter, and made of carbon composite (essentially strands of carbon fibre mixed with a polymer), while the bezel, pushers and crown are ceramic. And the crown guard and case back are titanium. Oversized and chunky with a carbon composite case, it looks like the typical Offshore but the movement is special. The calibre 2897 is an automatic chronograph with tourbillon, wound by a peripheral rotor. This movement is not new, but for the first time the winding mechanism has been revealed on the dial.
A cut-out at one o'clock shows the winding gear and the ball bearing for the rotor. And the chapter ring of the dial with the minute markings is actually clear sapphire, revealing the peripheral rotor with its teeth that run all around the edge of the dial.
