Panerai’s first breakthrough in chronographs came in 1943 when it produced the prototype for the Mare Nostrum, designed for use by deck officers of the Italian Navy. Now, after decades of technical advances, this sports complication par excellence returns to the Italian brand’s collections this year in the Luminor line. Instantly recognisable for its crown-guard and sandwich dial, this 44mm version is cut from steel. The Chronograph is operated by two pushers on the left side of the case. A blue-tipped chronograph hand sweeps the white dial, completed by a “base 1000” tachymeter scale around the flange. Powering these functions is calibre P.9200, a new automatic movement.
