A luxury professional diving-inspired timepiece, the Rolex Yacht-Master features a robust Oyster Perpetual case crafted from 904L stainless steel—a corrosion-resistant alloy favored for its superior polish and durability. The black dial is adorned with luminous white hour markers (dots, bars, triangle at 12 o’clock) and Mercedes-style hands, ensuring optimal legibility. A distinctive blue cyclops lens magnifies the date window at 3 o’clock, while the unidirectional rotatable bezel with engraved numerals (0–60) enables precise timing—ideal for sailing or water sports. The watch is powered by Rolex’s Calibre 3235 automatic movement, a Superlative Chronometer certified to +2/-2 seconds per day. Its Oyster bracelet with Glidelock clasp offers micro-adjustment for comfort. Though styled as a nautical tool, its refined finish and iconic design make it equally suited for formal events or daily wear. The presence of protective plastic film with '904L' markings confirms authenticity and new condition. Water-resistant to 100 meters, it balances rugged functionality with elegant sophistication.
