Trade In
Details
Diamonds, Rubies, And Solid Gold
Since its introduction, the Day-Date has been Rolex's definitive statement of prestige, offered exclusively in precious metals. This reference 18378 from 1995 is a direct descendant of that original vision, but executed at the level of high jewelry. The factory gem-setting is not an afterthought but an integral expression of the model's top-tier status. Here, a full suite of diamonds is anchored by four cardinal rubies on both the dial and bezel. This symmetrical and considered layout elevates the watch from a simple gold timepiece to a truly uncommon configuration.
The Double Quick-Set Caliber 3155
This Day-Date is powered by the automatic Caliber 3155, a movement that introduced the highly practical double quick-set function. This allows both the day and date displays to be adjusted independently via the crown, a significant technical leap that defined the modern generation of the reference. The entire watch is constructed from solid 18K yellow gold, from the 36mm Oyster case to the President bracelet, giving it a substantial weight of nearly 138 grams. Its factory-set bezel and champagne sunburst dial, both adorned with diamonds and rubies, mark it as a premier example from the period.
An Excellent Factory Example
Remnants of the original factory caseback sticker are still intact, speaking to the careful history of this watch. This piece presents in Excellent Vintage Condition, with a sharp case and a President bracelet showing minimal stretch for its age. The champagne tritium dial is flawless, and all factory-set diamonds and rubies on both the dial and bezel are secure and brilliant. As with every watch we offer, this piece has been verified as mechanically sound and is ready to wear.
Wearable Luxury, Built To Last
Where a traditional gold dress watch from another house might demand careful wear, this Day-Date offers a different proposition: robust, wearable luxury. It combines the prestige of a factory diamond-and-ruby setting with the proven durability of an Oyster case and the everyday convenience of an automatic movement. It's a statement piece that doesn't need to be handled delicately. The watch offers the best of both worlds, pairing the highest level of precious material finishing with the reliability that has long defined Rolex.
