Breitling’s most iconic chronograph, the Chronomat, just got slimmer, sharper, and more integrated
Breitling refreshes the Chronomat with its most significant update since 2020
The Breitling Chronomat is back and the 2026 update arrives with three watch variants: the chronograph B01 42, the new automatic B31 40, and the classic automatic 36.
All three share similar traits – a fully integrated case and bracelet that feels like a natural evolution for the Chronomat lineup.
So yes, as stunning as the watches are, the biggest change here is the bracelet integration. The semi-integrated design of the outgoing model is gone, replaced by a fully integrated setup with concealed lugs.
Crucially, Breitling hasn’t sacrificed the ability to change straps in the process, which is great news if, like me, you like to change your watch straps every other week.
The Rouleaux bracelet now features a new micro-adjustment system on steel and two-tone models, letting you extend the bracelet by one link on each side of the clasp (even while wearing it).
It’s a small touch, but these small details make living with a watch much easier to live with.
The B01 42 chronograph is the headline act (especially with the ice blue dial). Its case has been slimmed from 15.1mm to 13.77mm, which is pretty significant, and the crown guard is smaller too, making winding and setting less fiddly.
Inside sits the proven COSC-certified Caliber 01, still delivering 70 hours of power reserve.
The B31 40 is the real surprise of the lineup. It marks the first time Breitling has offered a time-and-date-only Chronomat in a 40mm case.
It’s powered by the new manufacture Caliber B31, and the whole watch comes in at a very wearable 10.99mm.
The power reserve stretches to 78 hours. It’s a very compelling package.
The 36mm automatic rounds out the family, now slimmed to just 9.68mm. It runs on Breitling’s Caliber 10, a COSC-certified Sellita-based movement with a 42-hour reserve.
Across all three, the bezel on the chronograph model has been consolidated from 18 separate components into a single integrated piece, making it both cleaner to look at and, presumably, more robust.
The full collection is available now at Breitling boutiques and authorised dealers, priced from $5950 in the US and £4750 in the UK.
