This reference features a modular case construction combining 18k white gold and titanium, measuring 59mm x 38mm x 13mm. It utilizes the Girard-Perregaux based HM2 engine, a Jean-Marc Wiederrecht-designed movement featuring the first mechanical movement to offer instantaneous jumping hours, concentric retrograde minutes, retrograde date, and a bi-hemisphere moon phase. The \"Diamond-Set\" designation refers to the 20 diamonds totaling 0.54 carats set into the case. Collectors value the HM2 as the brand’s second-ever release, representing the early architectural era of Max Büsser’s designs. On the secondary market, this specific reference typically trades in the $60,000 to $90,000 range.
