Jean Perret is adding a model in gilt steel to its Doublette line, with impressively alternating polished and mat finishes. This model with its highly original second time zone is made up of two “superimposed” cases. The first case with its dial of Roman numerals can be released by gently pressing on it; this then reveals a second dial with Arabic numerals. The back of the first case can be decorated with a personalised engraving.
