Brand New, Pierre DeRoche Grandcliff GMT Power Reserve – Steel A Swiss rarity — from the current collection, now exclusively on Catawiki ***** A first-ever public sale — Pierre DeRoche has never offered discounts or special sales of any kind. For collectors and horology lovers, this is a chance not to be missed. Independent Swiss watchmaking from the Vallée de Joux, founded by Pierre Dubois and deeply connected to Dubois-Dépraz, one of the world’s foremost creators of high-end movement complications with over a century of expertise. This model houses an exclusive Dubois Dépraz caliber and a rare complication: the GMT mechanism is directly coupled with the date, allowing the date display to jump forward or backward when crossing midnight during local time adjustment. A technical refinement found only in very few haute horlogerie creations. Crafted with high-end techniques and premium materials, the Grandcliff GMT Power Reserve combines Swiss precision engineering with an exceptional design, ensuring both exclusivity and uncompromising quality. Each detail, from the guilloché dial to the engraved oscillating weight, reflects the brand’s dedication to innovation and rarity. ***** Model Information Model: Grandcliff GMT Power Reserve Reference: GRC10002ACIO-001CRO Condition: Current Collection – Brand New (Pictures are illustrative; unique numbers may differ) Including: 2 Years International Warranty – Papers – Original Box Movement and Functions Movement: Self-winding mechanical, Dubois Dépraz calibre 333 (PDR 4007 GMT – Power Reserve) Diameter: 26.20 mm – Thickness: 6.45 mm Frequency: 4 Hz (28,800 vibrations/hour) Jewels: 21 Power reserve: 42 hours Rotor: Nickel silver oscillating weight, cut and engraved, on ball-bearing mechanism Functions: Hours, minutes, seconds Second time zone (GMT – local time with independent correction) Date coupled to GMT (jumps forward or backward when passing midnight) Power reserve indicator Special Feature The GMT complication is not only original in its off-center display but also in its technicality: the date is mechanically linked to the GMT adjustment.
