Rolex Daytona 126519LN

Rolex Cosmograph Daytona "Bright Black Diamond" reference: 126519LN features a refined 40 mm Oyster case crafted from solid 18-carat white gold, showcasing polished lug shoulders, mirror-finished case flanks, and a protective black monobloc Cerachrom ceramic bezel with an engraved tachymeter scale used for mapping track speeds. Beneath the scratch-resistant sapphire crystal lies the striking bright black and steel dial, uniquely elevated by eight factory brilliant-cut diamonds set in 18-carat gold square mountings which serve as hour markers, while traditional white gold baton indexes with Chromalight luminescent fill sit at the 3, 6, and 9 o'clock positions. This face layout is beautifully contrasted by three steel-toned (silver) chronograph subdials tracking elapsed hours, elapsed minutes, and running small seconds. Powering the timepiece is the state-of-the-art, in-house Calibre 4131 automatic self-winding movement, a 72-hour power reserve and water resistant up to 100-meter.
