A Guide to Rolex Watch Materials: Oystersteel, Rolesor, and Cerachrom

1. Oystersteel: The Cornerstone of Rolex's Durability

Oystersteel, an alloy of 904L stainless steel, is a staple material in the world of Rolex watchmaking. This superalloy is known for its exceptional resistance to corrosion, making it ideal for use in the harshest environments. Oystersteel can be found in the construction of the cases and bracelets for most of Rolex's professional and sports watch models, including the renowned Submariner, Daytona, and GMT-Master II.

Rolex uses 904L stainless steel due to its ability to maintain its sheen and structural integrity even under extreme conditions. Additionally, Oystersteel can be polished to a brilliant finish, ensuring the timepieces maintain their stunning visual appeal for years to come.

2. Rolesor: The Art of Fusing Gold and Steel

Rolesor is a term coined by Rolex in 1933 to signify the combination of Oystersteel and gold in a single timepiece. This fusion of materials has become a hallmark of the brand's elegant and sporty watches. Rolesor watches often feature a stainless steel case and bracelet, adorned with gold elements on the bezel, crown, or center link. You can find Rolesor in various color combinations, such as yellow gold and steel, known as Yellow Rolesor, or Everose gold (Rolex's proprietary rose gold) and steel, known as Everose Rolesor.


The use of Rolesor allows Rolex to offer timepieces that artfully blend the durability of Oystersteel with the prestige and warmth of gold. This unique combination of materials has been seen in several Rolex collections, including the Datejust, Submariner, and Yacht-Master.

3. Cerachrom: Revolutionizing Bezels with High-Tech Ceramic

Introduced in 2005, Cerachrom is a proprietary ceramic material developed by Rolex to overcome the limitations of traditional aluminum bezel inserts. Cerachrom bezel inserts offer superior resistance to scratches, fading, and corrosion, ensuring their vibrant colors and legibility remain consistent over time.

The manufacturing process for Cerachrom is highly intricate, involving an initial molding of the ceramic material, followed by a meticulous process of diamond-polishing and laser-engraving the numerals and graduations. Due to its highly specialized production process, Cerachrom is only available in a select range of Rolex models, including the GMT-Master II, Submariner, Daytona, and Yacht-Master.

The exceptional properties of Cerachrom have allowed Rolex to elevate the performance and aesthetics of watch bezels, enhancing the resilience and enduring charm of their timepieces.

4. Other Noteworthy Rolex Materials: Everose Gold and Platinum

Rolex's pursuit of excellence also extends to its use of precious metals in watchmaking. Everose gold, a unique alloy of 18-karat rose gold, was developed by Rolex to maintain its color and luster over time. Unlike traditional rose gold alloys, which can gradually fade with prolonged exposure to various elements, Everose gold retains its rich hue, thanks to the addition of palladium to the mix. Today, Everose gold can be found in various Rolex collections, including the President, Daytona, and Yacht-Master.

Platinum, another revered material, is reserved for Rolex's most exclusive models. This dense, rare, and luxurious metal is primarily utilized in the Rolex Day-Date and the ultra-rare Cosmograph Daytona. Platinum's enduring beauty, weight, and resistance to tarnishing make it a highly sought-after material in the realm of luxury timepieces.

Appreciating the Sublime Craftsmanship Behind Rolex Watches

The art and science of Rolex watchmaking transcend the realms of timekeeping and design, encompassing an unwavering dedication to sourcing and developing the finest materials available. The use of Oystersteel, Rolesor, and Cerachrom exhibits Rolex's commitment to creating watches that not only exude elegance and prestige but also possess the strength and resilience to stand the test of time.
