"The new Calibre 2550 is an impressive 2.4mm thick and is the successor of the historic Calibre 1120, which has been a benchmark in ultra-thin watchmaking since 1968."
"Three elements make this possible: a platinum micro-rotor integrated into the mainplate, a suspended double barrel for extended power reserve, and a redesigned single-level gear train."
"The calibre makes its debut in the new Overseas Self-Winding Ultra-Thin, which is limited to 255 individually numbered pieces, crafted from 950 platinum."
"The optimised alloy used in the case, bracelet, and clasp has 2.7 times greater hardness than standard platinum, enhancing protection against scratches."
The Calibre 2550 movement by Vacheron Constantin is a breakthrough in ultra-thin watchmaking, measuring just 2.4mm thick. It succeeds the historic Calibre 1120, which was 2.45mm thick. The new movement features an 80-hour power reserve, achieved through innovative design elements such as a platinum micro-rotor, a suspended double barrel, and a single-level gear train. The movement debuts in the limited edition Overseas Self-Winding Ultra-Thin, crafted from 950 platinum, which offers enhanced scratch resistance.
