"Lefty" pilot's chronograph named after the Fiat CR.42 fighter that Giosuè Calamai flew (Monochrome), in 49 numbered pieces; sold out and listed under the brand's past collections. Brand specs: Ø42mm, 14.90mm thick, steel cast from F-104 Starfighter turbine steel, screw-down crown, dark grey dial, AR-coated sapphire, 5 ATM, Valjoux 7750 automatic chronograph, 22mm Italian full-grain leather strap in grey and camel with pin buckle, made in Italy. Monochrome's 2017 review adds the rest: chronograph pushers on the left side of the case and a second crown on the right that turns a bidirectional internal bezel, a reversed 7750 layout (12-hour counter at 12, small seconds at 3, 30-minute counter at 6) with the date at 4:30, a fully brushed case and an engraved solid caseback carrying the serial number of the turbine its steel came from; it gives the diameter as 42.5mm (the brand says 42mm, recorded), a price of EUR 2,850, and an optional steel bracelet alongside the leather straps. The brand's terms of sale say prices include IVA (Italian VAT).
