Breitling · Avenger B01 Chronograph 42 · black · steel bracelet · on Amazon
The Avenger B01 at 42mm. The 01 in a 300-metre case.
This is Breitling’s tool chronograph in its smallest size: the 2023 Avenger B01 Chronograph 42, reference AB0146101B1A1, a 42mm steel case 15.05mm thick with a unidirectional rider-tab bezel, a black dial with three black counters and oversized luminous markers, the date at 4:30, on the steel bracelet. Inside is the manufacture calibre 01, a column-wheel automatic chronograph with about 70 hours of reserve and a COSC certificate, behind a sapphire caseback; 300 metres with a screw-locked crown. The least expensive B01 Breitling on this page, listed under Breitling’s price when we read it, from a marketplace seller.

The 2023 Avenger
Breitling rebuilt the Avenger in 2023: thinner cases, a cleaner dial with the big luminous markers kept, a rider-tab bezel that can be turned with gloves, and the manufacture 01 in the chronograph versions instead of the bought-in Valjoux of the old Avenger II. The 42mm B01 is the small one; the 44 and the 46 Super Avenger sit above it. 300 metres and a sapphire caseback in the same watch is unusual.
The Breitling 01 is the company’s own column-wheel, vertical-clutch automatic chronograph, introduced in 2009: 47 jewels, 28,800 vph, about 70 hours of reserve, COSC certified, and the reason a Breitling chronograph costs what it does.

Reading the listing
The listing carries the reference AB0146101B1A1 in the model row and calls it an Avenger B01 Chronograph 42, automatic, black dial, steel bracelet, and says little else. The photograph shows the rider-tab bezel, the black dial with three counters, the date at 4:30 and the bracelet. The size, thickness, lug width, calibre, COSC certification, reserve, 300 metres and sapphire caseback are Breitling’s published figures for the reference.
The seller is Watchsavings, a marketplace seller, and the rows we read do not state whether the watch is new with Breitling’s five-year warranty; ask, and ask for the box and card. Nothing here was measured on the watch.

Buying it on Amazon
This is a regular Amazon listing from a marketplace seller with Amazon’s 30-day return window; it is not a Luxury Stores pre-owned unit and the seller has not published a condition. The second button opens the live search for Avengers in case this one has sold.
Avengers have resold for under new and close to what pre-owned buyers paid, sometimes more, sometimes less; that is a pattern, not a promise, and nothing here is investment advice.
