The Rolex Oyster Perpetual Yacht-Master, a sailors’ watch introduced in 1992, underwent a major facelift in both its design and technology in 2012. In this popular article from the WatchTime archives, we take a closer look at it.
Rolesium, a material developed by Rolex and used here in the Yacht-Master’s 40-mm diameter Oyster case, is an alloy of 904L stainless steel and platinum. The bezel, which rotates in both directions and now has a notched ring with 120 gradations, is made entirely of 950 platinum. It has a smooth, sand-blasted finish, except for the raised numerals and indices, which are polished. The hour markers on the nautical-looking blue dial are made of 18k white gold and filled with a luminescent material called Chromalight, which gives off a strong, blue-tinted glow in the dark. Rolex’s traditional Oyster case — with a middle piece crafted from a solid block of the corrosion-resistant alloy and a fluted, hermetically screwed caseback — is water-resistant to 100 meters. The screw-down crown is protected by a crown guard built into the middle case and also features the patented Triplock water-proofing system. Another Rolex trademark — the “Cyclops” magnifying lens over the date, is found at 3 o’clock and made of highly scratch-resistant synthetic sapphire.
Inside the Yacht-Master beats Rolex’s manufacture Caliber 3135, an automatic movement that has been certified by the Swiss testing agency COSC as a chronometer. Like other Rolex movements, it features an oscillating system with a blue hairspring made of Parachrom, an alloy developed and patented by Rolex. According to the company, this hairspring is highly resistant to shocks, magnetic fields and temperature variations, which ensures greater stability in timekeeping precision.
A sold-link Oyster bracelet in 904L stainless steel completes the package, with polished center links and satin-finished outer links. The improved Oysterlock safety clasp, another patented Rolex development, has a security system to prevent accidental opening and also contains the Easylink quick-extension technology, which lets the wearer easily increase the bracelet length by about 5 mm. Technical specs for the Rolex Oyster Perpetual Yacht-Master (retail price: $11,550*) can be found below the photo.

I’m interested in purchasing, could you let me know how I can get a hold of one?
You can buy it on Amazon right now from several sellers but with the 3135 movement. FYI Rolex has put the 3235 movement in this model but I don’t know where you would find one since the AD’s don’t have any (any of pretty much all the stainless sport watches)
I do believe that the case is in fact solid 904L steel, and not as you mention: “Oyster (monobloc middle case, screw-down caseback and winding crown) made of Rolesium (combination of 904L stainless steel superalloy and 950 platinum)”
This is a quote from the ROLEX website:
Yacht-Master Model features:
Many Rolex watches are available with the now-legendary combination of yellow, white or Everose gold and steel known as Rolesor, but Rolesium is a creation specific to the Yacht-Master. While the case and bracelet are in rugged 904L stainless steel, the bezel of the Rolesium versions is made of 950 platinum, imparting a silvery whiteness and vibrant luminosity for an unmistakable sense of luxury.
The case and bracelet are stainless steel and not a combination of steel and platinum, but I have seen this verbatim description before.
Hi all, wondering if someone could assist? On the platinum dial model, can sonmeone confirm if the so-called “rolesium” material of the case is a mix of steel and platinum, or is it 100% steel, leaving the bezel and dial as the only parts containing or made of platinum ?
What is the cost and is it available now?
Can anyone tell us how much this retails at in the uk
It is beautiful… Does anyone know the price?
simply stunning…..is the blue dial made of platinum? thanks
Yes, I believe it is made from platinum blended with “Indigoium”.
Great post. Keep us update with your developments!
