Rolex Datejust 31 mm

Rolex Datejust 31 mm, reference 278384RBR-0036, cased in 31 mm of steel and white gold, is a chronometer built for a woman's wrist. The diamond-set bezel frames a pink dial also set with diamonds, and a sapphire crystal with a Cyclops lens sits over the date window. Inside runs calibre 2236, a self-winding movement with a Syloxi hairspring and Paraflex shock absorbers, giving roughly 55 hours of power reserve. The screw-down crown adds a second waterproofing barrier beyond the case itself. Central seconds and instantaneous date round out the functions. The watch is fitted to a Jubilee bracelet in steel, closed by a concealed folding Crownclasp in steel and gold. Water resistance reaches 100 metres, a figure the screw-down crown helps maintain.
