Breitling has long been the adventurer’s watch brand: distress signals, monster water depth, radio capability and so on and so forth. It’d be easy to assume, then, that the long and complex reference numbers are just another facet of the superspy aesthetic – a unique number only decipherable by 007s-in-training. Well, there’s more purpose to the code than you’d think – and it’s a code Montredo has cracked.
The sole purpose is identification: no two Breitling watches will ever boast the same serial number. Handy for insurance, the pre-owned market and the like. The reference number however – a separate figure – tells more about the watch, its functions and what makes it tick.
Over the years, Breitling has tweaked this system internally, which explains some disparity between older models. From 1991 onwards though, the Swiss label has stuck to one overarching method that applies to all modern watches. Any pieces manufactured before this date are very much considered vintage, and that’s a different game entirely when it comes to value and re-sale stakes.
For modern pieces, i.e. models that are introduced after 1991, reference and serial numbers usually adopt a six digit figure as part of a larger serial number. For example, the A68362 – the non-SuperQuartz COSC-certified B1- or AB0110 – the in-house movement Chronomat 44. The very first letter refers to case material. Since most Breitlings are crafted in stainless steel, you’ll usually find a letter A, though there are plenty of other variations as below.
The second and third digit refers to calibre number. Now, this is where it gets a little more complicated. Anything ranked 50 or above signals a quartz movement, while new in-house movements are given an extra B before the caliber number – so B01, for example.
If there’s no sign of a B however, the movement has been sourced from an external supplier, likely Venus, Lemania, ETA, Valjoux or Piguet – just five manufacturers that have long partnered with Breitling. Out-of-house movements don’t mean lesser quality, though. Such watches are often subjected to heavy modification once at Breitling – the Chronomat 01 and the Transocean Chronograph Edition, for example – whether that’s to improve chronometer performance or add further complications (and with it, cost).

The fourth digit is related to the movement, too. And yes, it is as complex as it sounds. If the movement was made by a partner of Breitling, as opposed to in the manufacture itself, 0 means it has not received COSC certification. 3 however, means that it has, so expect a more precise watch as a result. This isn’t a blanket rule though, as certain pieces break the rules: a non-COSC Astromat A20405 model boasts a 4. If you’re unsure if your watch has such credentials, it’s worth asking the experts: all good Breitling retailers (and the brains behind them) should be able to tell you exactly how your watch ticks along. Either that, or by taking stock of the production year – since the turn of the millennium, most Breitling pieces have all been COSC certified.
Unlike other sectors of the reference number, the fifth and sixth digit only loosely refer to particular model types – there appears to be no blanket formula. That said, there are some instances in which the same numerals correspond to different models, but this is largely without method.
There’s much debate about what the seventh and eighth digit directly refer to, though many believe it to be the bezel – and with good reason.
Five codes are used heavily throughout Breitling families in reference to specific finishes. These are as follows:
So far, so flashy. Other codes however, take the seventh and eighth digit with no real pattern spotted. These include:
Since Breitling’s reference numbers are of such a flexible basis, you may find exemptions to the arrangements listed. No bad thing. However, a loose guide can provide insight into your watch serial number, giving you a base understanding of what is in your watch, and where it’s come from. Here are a few of our favourites to clock up your interest.
One needs not to be a professional race car driver to adorn his or her wrist with a chronograph. Much like Breitling’s Navitimer 01 43, an aviation spin can land even the most functional of watches on the smartest of wrists, with a monochrome palette guaranteed to clinch the cost-per-wear ratio.
Milanese bracelets have long been something of a trend in the watch world. So too have black dials. Consider, then, the Breitling Superocean to be a rare combination of both, pitting two enduring motifs within one versatile, handsome shell.
If a Himalayan expedition to conquer Everest is unfeasible right now, the Breitling Avenger Hurricane 50 is probably your next best thing. Composed of a durable Breitlight material, this all-black wonder is as robust as it is flexible, boasting enough function and power to last even the mightiest of adventures.
Steel resolve can now extend to the wrist courtesy of Breitling. The Super Avenger II 48 Chronograph isn’t just a pretty face though, packing a highly accurate movement inside a highly durable, stylish home.
For those who sniff at rubber straps, simply dangle the Breitling Colt 44 Chronoemter under their nose. Whilst inherently a sportswatch, the Colt 44 treads into smarter territory thanks to a cool, classic aesthetic that’ll score points outside the locker room, too.
