Oystersteel: This is 904L grade steel, a superalloy used in the aerospace and chemical industries, and that means it has the corrosion resistance and high polish of precious metals. It also has a high sheen, so it looks good for a long time.
Everose Gold: By adding copper and silver to gold in its proprietary formula, Rolex achieves its uniquely warm rose gold. Rolex also uses its own formulas of 18k yellow and 18k white gold.
Platinum: Rolex uses 950 platinum, a high-concentration alloy that includes ruthenium for strength and shine.
Rolesor: This is a name Rolex gives to its patented method of combining Oystersteel and gold in its two-tone models. The bezel, the winding crown, and the center bracelet links are made of 18k yellow or Everose gold, and the middle case and outer links of the bracelet are made of Oystersteel.
Cerachrom: Rolex’s proprietary ceramic is made in-house. It is scratch-proof, impervious to UV rays (it doesn’t fade), and it is now the standard for bezel inserts on Rolex’s sport watches.

Chromalight: Rolex’s luminescent material — blue by night, bright white by day — providing high visibility in dark environments.
BRACELETS: Jubilee Bracelet: The supple five-piece links on dressy watches and some sport watches, such as the GMT-Master II. It was originally designed for the Datejust in 1945.
Oyster Bracelet: The larger, flat, three-piece links make for a simpler, sportier look.
President Bracelet: The President uses semi-circular three-piece links, originally created in 1956 for the Day-Date. It is always 18k yellow, white, or Everose gold, or 950 platinum.
Pearlmaster Bracelet: The refined five-piece links make the Pearlmaster Rolex’s most elegant bracelet, found only with a crownlock clasp.
Oysterflex Bracelet: Made of a very soft, flexible elastomer with an internal cushion system that makes it extremely well fitting and comfortable. The bracelet is fitted over a metal blade made of a titanium and nickel alloy, achieving the strength of metal and the comfort of rubber.

BEZELS: Fluted Bezels: Iconic and hard to miss, today’s fluted bezels are one of the great signature elements of Rolex timepieces. Engraved Fixed Bezels: Found on the Explorer II and the Cosmograph Daytona, demarcations are engraved into either Oystersteel, a precious metal, or Ceracrom.
Rotating Bezels with Inserts: Used for Professional watches. Scratch-proof Cerachrom inserts are the norm.
Rotating Precious Metal Bezels: Exclusive to the Yachtmasters, these are sporty, deeply engraved bezels.
