Rolex Day-Date 36 36 mm 118388GSO Yellow Gold/Diamonds Green

The Rolex Day-Date 36 reference 118388GSO is one of the most coveted configurations in the entire Rolex catalog — a 36mm timepiece crafted entirely in 18k yellow gold, dressed with a diamond-set case and bezel, finished with a luminous green dial, and secured on the iconic Oyster bracelet. First introduced in 1956, the Day-Date was the world's first wristwatch to display both the day of the week spelled out in full and the date, and it has been manufactured exclusively in precious metals ever since. The reference 118388GSO sits firmly within that storied lineage while pushing its aesthetic ambition to a spectacular extreme.

The green dial of the 118388GSO is an immediately arresting choice. Green has long been associated with prestige and exclusivity in the Rolex world, and on this reference it is framed by a diamond-set bezel and diamond-set case sides that amplify the jewel-like quality of the entire watch. The Oyster bracelet — Rolex's most enduring and functional bracelet design — grounds the watch in the brand's tool-watch heritage while the precious materials elevate it firmly into haute horology territory. Every surface of this reference communicates rarity.

Powering the Day-Date 36 is a Swiss automatic movement, a self-winding caliber built and certified in-house by Rolex to its famously stringent tolerances. Rolex movements in the Day-Date family are renowned for their reliability, precision, and longevity, and they carry the brand's Superlative Chronometer certification, which guarantees accuracy to plus or minus two seconds per day when tested by Rolex after casing. The movement is protected by the Oyster case, which Rolex rates to 100 meters (330 feet) of water resistance — an impressive specification for a dress watch of this caliber.

On the wrist, the 118388GSO commands attention without effort. The 36mm case size occupies a sweet spot that has dressed the wrists of world leaders, CEOs, and tastemakers for more than six decades. It is not a small watch by historical standards, and its diamond-set case and bezel ensure that it catches light from every angle. Whether worn at a black-tie event, a boardroom, or a private dinner, this Day-Date communicates achievement and refined taste in a language that is universally understood.
