ROLEX GMT-MASTER (Free-sprung) RFS0001

ER Factory "Free-sprung Balance" GMT — The Ultimate Rolex GMT-Master II "Coke" Bezel

40mm case diameter; the entire case is crafted from 904L steel with upgraded metal brushing techniques, delivering a refined, tactile finish identical to the genuine article.

Features an exclusively developed red-and-blue ceramic bezel; repeated color calibration and firing processes have achieved zero color deviation, while the silver-plated bezel markings boast a fine texture and brilliant luster.

The black dial is deep yet elegant; the logo typography has undergone multiple rounds of fine-tuning against the genuine version to eliminate any discrepancies.

Swiss-imported luminous material is used throughout for the hour markers and hands, matching factory standards for the genuine model in both grain texture and glow performance.

Every link of the 904L steel bracelet is individually polished, with inter-link gaps precision-adjusted to the micron level to achieve the same "supple" feel as the genuine watch.

The movement represents the culmination of years of R&D and iterative upgrades, resulting in a market-leading, top-tier Cal. 3285 movement featuring a free-sprung balance system.
