This piece in the Chopard Mille Miglia GTS collection differs from the three-hand Automatic and the Power Control, which have in-house Chopard movements, because the Chrono has a third-party movement, the ETA Valjoux 7750 automatic chronograph calibre, providing 48 hours power reserve, and a COSC-certified chronometer. The Chrono is a millimetre wider than the other two at 44 mm, thicker at 13.97 mm. The solid caseback is marked with the Mille Miglia logo and the lettering “Brescia > Roma > Brescia.” The case is water-resistant to 100 metres.
The motor-racing spirit of the watch is reinforced by the tyre-tread rubber strap, the Mille Miglia red arrow logo, and the chronograph pushers that resemble car pedals.
The Valjoux 7750 movement by ETA is one of the most frequently-used chronograph movements, with a coulisse-lever system for starting, stopping and resetting the chronograph, instead of the column wheel. The major difference between the two systems is that in the lever-operated movement, the buttons require more force to press. The coulisse-lever system requires less precision in the manufacture of the levers and springs and so costs much less to build.
