## Overall Watch Rating: 9.0/10.0

**Material Metric (9.8/10.0)** - Rolex's Oystersteel construction with sapphire crystal and Cerachrom bezel delivers top-tier durability and premium finishing akin to the best Submariner models.
**Movement Metric (9.8/10.0)** - The Caliber 3285 exemplifies Rolex engineering with its chronometer-certified precision, Parachrom hairspring, and extended 70-hour reserve, rivaling the elite in-house calibers from Patek Philippe.
**Dials & Design Metric (9.5/10.0)** - The Sprite bezel's vibrant green-black gradient and lefty ergonomics offer a fresh, iconic evolution of the GMT formula, standing out like a modern update to the classic Pepsi GMT.
**Versatility Metric (9.3/10.0)** - Seamlessly transitioning from boardroom to cockpit with 100m water resistance and GMT functionality, it matches the all-scenario prowess of the standard GMT-Master II.
**History & Innovation Metric (9.4/10.0)** - Rooted in Rolex's aviation heritage since the 1950s with cutting-edge ceramic bezel tech and left-handed innovation, it builds on a legacy comparable to the original GMT-Master.
**Brand Metric (8.8/10.0)** - Rolex commands luxury prestige through unmatched reliability and global recognition, on par with Omega's upper echelon.
**Complications Metric (8.0/10.0)** - The independent GMT hand and quickset date provide practical dual-time utility, solid like most traveler's watches but without haute complications.
**Functions Metric (8.5/10.0)** - Core timekeeping plus GMT and magnified date deliver reliable everyday utility, exceeding typical luxury sports watches.
**Rarity Metric (7.7/10.0)** - At around $11,350 MSRP with high production volumes, its exclusivity mirrors other popular Rolex steel sports models on the secondary market.
