QF Edition — Oysterflex Elastomer Strap
The QF 126515LN establishes a benchmark in the precious metal replica category by addressing the most common collector critique: weight. By integrating a tungsten alloy core, this case achieves a substantial 155g mass, closely mimicking the tactile heft of solid Everose gold on the wrist.
At its core operates the SH4131 clone caliber, engineered specifically to replicate the updated 12-series architecture. It features the revised bridge layout and modernized rotor design, delivering reliable chronograph functionality while maintaining a power reserve of approximately 36 hours.
Constructed from 904L Oystersteel beneath its 18k rose gold PVD coating, the 40mm case correctly integrates the new metal-rimmed Cerachrom bezel. The chocolate sunburst dial, exhibiting deep #6b3e26 tones under direct light, is finished with the refined, slimmer hour markers and authentic Chromalight luminescence.
