Rolex’s calibre 3135 self-winding movement is the powerhouse behind this impressive Date watch. ?Introduced in 1988, the 3135 movement is still considered by many as one of Rolex’s best movements to date with the addition of a Paramagnetic blue Parachrom hairspring, 31 jewels, and the innovative Quickset function. ?Rolex houses all of its movements within a carefully design Oyster case built with an intricately designed screw-down system within the crown that helps to protect against depths of up to 330 feet. ?This notoriously sturdy construction provides protection against everyday wear and tear. ?The reference 15210 that is offered here today show cases the impressive 34mm Oyster case and 3135 COSC certified movement as well as a sleek all-steel design. ?A brushed stainless steel, flat link Oyster bracelet with Fliplock clasp is paired with a matching engine turned bezel, offering a striking contrast for the black dial. ?Silver index hour markers, sweeping hands, and the iconic date aperture top the dial to create a classic Rolex design that begs to be worn.
