Understanding Breitling Reference Numbers
Breitling uses a structured alphanumeric reference number system that provides insight into a watch’s collection, movement, and case material. Over the years, Breitling has updated its numbering conventions, so older and newer watches may follow slightly different formats.
The standard Breitling reference number format looks something like this:
Example: AB0127211B1A1
Let’s break it down into its key components.
1. First Letter(s) – Case Material
The first one or two letters in the reference number indicate the case material:
- A – Stainless Steel
- B – Stainless Steel & DLC (Diamond-Like Carbon)
- C – Stainless Steel & 18k Gold
- D – 18k Gold & DLC
- E – Titanium
- F – Titanium & 18k Gold
- J – Solid 18k White Gold
- K – Solid 18k Yellow Gold
- L – Solid 18k Rose Gold
- M – Blacksteel (DLC-Coated Stainless Steel)
- P – Platinum
- R – Red Gold
- U – Two-Tone Steel & Gold

For example, in AB0127211B1A1, the first letter “A” tells us the watch has a stainless steel case.
2. First Two Digits – Movement Type
The next two numbers represent the movement caliber inside the watch. Breitling’s in-house and third-party movements have specific number designations:
- 01 – Breitling Caliber 01 (in-house chronograph)
- 02 – Breitling Caliber 02 (manual-wind chronograph)
- 09 – Breitling Caliber 09 (manual-wind, no date)
- 13 – Breitling Caliber 13 (ETA Valjoux 7750-based chronograph)
- 17 – Breitling Caliber 17 (ETA 2824-2 base movement)
- 32 – SuperQuartz Movement
- 73 – SuperQuartz Chronograph
For example, in AB0127211B1A1, the digits “01” indicate the watch features the Breitling Caliber 01, an in-house automatic chronograph movement.
3. Next Three or Four Digits – Model Code
These digits correspond to a specific watch model. Some common Breitling model codes include:
- 242 – Navitimer
- 271 – Premier
- 443 – Chronomat
- 765 – AVI Ref. 765
- 1884 – Limited Edition Model
For example, in AB0127211B1A1, the digits 2721 help identify the exact Navitimer model.
4. Following One or Two Letters – Dial Code
The next character(s) indicate the dial color:
- A – Silver/White
- B – Black
- C – Blue
- D – Green
- E – Anthracite
- G – Gray
- M – Mother-of-Pearl
- R – Red
- L – Brown
In AB0127211B1A1, the “B1” suggests a black dial variation.
5. Final Digits – Bracelet or Strap Code
The last characters specify the type of bracelet or strap:
- A1 – Stainless Steel Bracelet
- B1 – Leather Strap
- C1 – Rubber Strap
- D1 – Mesh Bracelet
- E1 – Fabric/NATO Strap
For example, in AB0127211B1A1, the A1 means the watch is fitted with a stainless steel bracelet.
Decoding Vintage Breitling Reference Numbers
Older Breitling watches may follow a different numbering system. Many vintage Breitling models have 4- to 6-digit reference numbers, often corresponding to a specific model series rather than including movement and material details. For instance:
- 806 – Navitimer from the 1950s–1970s
- 765 – AVI/Co-Pilot models
- 817 – Military Chronographs
If you own a vintage Breitling, cross-checking the reference number with production records and catalogs can provide more insight.
Conclusion
Breitling reference numbers might look complex at first, but once you understand the format, you can easily identify a watch’s material, movement, model, dial color, and strap. This knowledge is valuable for collectors, buyers, and enthusiasts looking to authenticate or learn more about their timepieces.
Whether you’re shopping for a Breitling or researching your own collection, decoding reference numbers is an essential skill for any watch lover.
