An often overlooked feature is that this 18ct yellow gold Tank Française Chronoreflex is a stealthy grand complication. It combines a split seconds chronograph with perpetual calendar programmed to the year 2100, and rapid hour change.

In beautiful condition, this is Cartier's gents Chronoreflex ref. 1830; instantly recognisable for its bold architectural case flanks and unmistakable clean lines. Recessed into the white roman dial are its chronograph counters at 4 and 7 o'clock, and the date register at 12.

A quarter turn of the sapphire-set crown, activates the rapid hour change sending the hour hand forward or backward an hour at a time. Repeat the same for minutes, for precision setting, all capable thanks to Piaget's ultra-slim Quartz calibre 212P.

Presented with its red Cartier box, instructions, Cartier warranty booklet, and under our two-year comprehensive warranty.
