There’s a quiet civil war among Breitling fans about which model is the most “Breitling” Breitling. The Navitimer crowd has the pedigree on its side, but the Chronomat camp has been gaining ground for a while now.
With today’s full collection overhaul spanning 22 references, they may have just won the argument outright.
Born in the Cockpit, Sharpened for the Boardroom
The Chronomat’s origin story is pure ’80s catnip. In 1983, then-owner Ernest Schneider linked up with the Frecce Tricolori, Italy’s hotshot aerobatic squadron, to build a mechanical chronograph that could survive a fighter jet pulling 20Gs. For reference, the human body taps out around 7Gs, so the engineering bar was, to put it lightly, absurd.
The production model launched in 1984 for Breitling’s 100th anniversary and became one of the few mechanical chronographs to gain real commercial traction during the Quartz Crisis.
A Slimmer, Cleaner Silhouette
Let’s talk about the headline change – the new sizing. The flagship B01 42 has dropped from 15.1mm thick down to just 13.77mm, and the lug-to-lug has also come down quite a bit, all the way from a hefty 50.5mm to a much more wearable 45.8mm.
The case and Rouleaux bracelet are now fully integrated, with the lugs hidden behind the case so you can still swap straps. Steel and two-tone bracelets pick up a tool-free micro-adjustment system in the butterfly clasp.
Up top, the rider-tab bezel has been simplified from an 18-piece construction into a single structure, the crown guards are trimmed down, and the 1/100 scale is gone from the rehaut. Dial options here include a proper panda, sunburst blue and green, plus an ice-blue dial paired with a platinum bezel that scratches the same itch as a platinum Daytona for a lot less money.
The 40mm Three-Hander Is the Sleeper Hit
For the first time, there’s a 40mm time-and-date Chronomat. Powered by the in-house Caliber B31 with a weekend-friendly 78-hour power reserve, it measures just 10.99mm thick.
This one lands in a sweet spot the Chronomat has always struggled to hit: big enough to feel like a Chronomat, yet still slim enough to disappear under a cuff.
