QF Factory Edition — President Bracelet
The QF Factory iteration of the Day-Date 36 (Ref. 128398TBR-0004) addresses a persistent limitation in precious metal replicas: overall mass. By integrating a tungsten-enhanced case core, this model achieves a confirmed weight of 155.1 grams, significantly narrowing the tactile delta between standard 904L Oystersteel replicas and genuine solid gold. This specific reference is highly scrutinized for its natural Mother of Pearl dial and custom diamond-set bezel, which QF executes with careful attention to structural tolerances.
Mechanical operations are driven by the Clone Caliber 3255 automatic movement. Unlike earlier ETA-based modifications, this bespoke architecture features the correct hand stack and an instantaneous day and date flip mechanism at midnight. Beating at a standard 28,800 vibrations per hour, it delivers a smooth sweep while maintaining a power reserve of approximately 36 hours.
Dimensionally, the case measures a period-correct 36mm in diameter and 12mm in thickness. The exterior is treated with 18k yellow gold plating over the tungsten and steel base. The dial features a natural (Note: While our system accentuates #006039, this specific reference utilizes a white iridescent Mother of Pearl) finish, paired with synthetic diamond hour markers and protected by a scratch-resistant sapphire crystal with a properly magnified Cyclops lens.
