Why the reference number matters when buying a Rolex
The Rolex reference number is the single most important identifier when buying or selling a pre-owned Rolex. It tells you exactly which variant you are looking at — case material, bezel type, dial color, and bracelet. Two watches that look similar can have completely different values based on their reference. A stainless steel Daytona (116500LN) and a white gold Daytona (116519LN) may look similar in photographs but differ by CHF 30,000 or more in price.
At LTW Trade SA in Lugano, every watch listing includes the exact reference number. We encourage buyers to verify the reference on the watch itself — not just in the listing — before completing a purchase.
How to read Rolex reference numbers
Modern Rolex references follow a structured format. The numeric part identifies the model family. Suffixes indicate material and features: LN = black ceramic bezel (Lunette Noire), LB = blue ceramic, CHNR = chocolate/black ceramic, etc. For example:
126610LN = Submariner Date (126610) + black ceramic bezel (LN)
126710BLRO = GMT-Master II (126710) + blue/red ceramic bezel (BLRO = Bleu/ROuge — Pepsi)
228238 = Day-Date 40 (228238) in yellow gold (no suffix needed — gold variants are the default)
What to do after looking up a reference
Once you have confirmed the reference, check that the dial, hands, bezel, and bracelet are consistent with that reference's known variants. Rolex does not offer every dial on every reference — if a seller is offering an unusual combination, that warrants scrutiny. Contact our experts if you need authentication support.
