Short answer

A replica Rolex Datejust Oyster bracelet is a three-piece link band with a folding clasp. The genuine version uses Oystersteel, a 904L stainless steel. Most replicas use 316L stainless steel. The main tells are the end links, the clasp stamping, and the center link polish.

Genuine Oyster bracelet specs

  • Three-piece links. Outer links brushed, center link polished.
  • Oysterclasp with a folding blade.
  • EasyLink extension of 5 mm on many modern references.
  • Oystersteel 904L on Datejust models from 2018 onward. Earlier models used 316L.
  • Measured lug width: 20 mm on the Datejust 36, about 21 mm on the Datejust 41. Confirm on your own case.

What differs on a replica

Steel

904L has more chromium, nickel, and molybdenum than 316L. It holds a polish longer and resists salt and sweat. 316L is softer and scratches deeper.

End links

Genuine end links sit flush with the case. Replica gaps run 0.2 mm to 0.5 mm on many builds. A gap shows as a dark line at the lug.

Clasp

Genuine clasps use raised stamping. Some replicas use laser etching. Look inside the clasp for molding marks.

Links and pins

Low-tier builds use hollow mid-links. High-tier builds use solid links. Some replicas use push pins in place of screws.

How to size a replica Oyster bracelet

  1. Measure the lug width with calipers.
  2. Count the links and note which ones remove.
  3. Pull links from the 6 o'clock side first, then the 12 o'clock side. This keeps the clasp centered on the wrist.
  4. Use a 1.4 mm or 1.6 mm screwdriver on slotted screws.
  5. Use a link remover and light taps on push pins.
