TWF Edition — Integrated Steel Bracelet
TW Factory (TWF) presents a compelling iteration of the Vacheron Constantin Overseas Perpetual Calendar, balancing complex dial architecture with a verified 11.6mm case profile. This release addresses previous market limitations by refining the module integration, allowing all sub-dial complications to function reliably while maintaining the distinctive Maltese cross bezel geometry.
Powered by a robust Asian 2836-2 base movement heavily modified to replicate the visual architecture of the Caliber 1120 QP/1. The movement features a customized compass rose rotor and decorative plates, delivering a stable beat rate and approximately 36 hours of power reserve. The modular approach ensures the day, date, and month indications operate smoothly.
Crafted from 316L stainless steel with a 904L steel integrated bracelet, the 41.25mm case weighs exactly 164.4g, offering substantial wrist presence. The crisp white dial—often paired by collectors with a deep green aftermarket rubber strap for contrast—displays the calendar functions with sharp typographical precision.
