Breitling · Chronomat B01 42 · steel and red gold · blue · on Amazon
The two-tone Chronomat. Red gold rider tabs, Rouleaux bracelet, the 01 inside.
This is the Chronomat in its loudest metal: reference UB0134101C1U1, a 42mm steel case with an 18k red gold bezel carrying the four rider tabs and the tachymeter ring, a blue dial with three black counters and a date at 4:30, red gold crown and pushers, on the steel and red gold Rouleaux bracelet, the rolling-link bracelet Breitling brought back with the 2020 Chronomat. Inside is the manufacture calibre 01, a column-wheel automatic chronograph with about 70 hours of reserve and a COSC certificate; 200 metres. Breitling’s 2026 Chronomat B01 42 has replaced this reference, so it is the outgoing generation, listed under Breitling’s last list price from a marketplace dealer; the Amazon title says green, the watch is blue, and the copy says so.

The 2020 Chronomat, and what replaced it
Breitling relaunched the Chronomat in 2020 as a steel sports chronograph built around the 1984 original: rider tabs on the bezel, the Rouleaux bracelet of rolling links, the 01 calibre. UB0134101C1U1 is the two-tone version, red gold bezel, crown, pushers and bracelet centre links against a blue dial, and it was the top of the 42mm steel-and-gold range at USD 14,900 until the 2026 update replaced the UB0134 references with the UB0158 series. Same calibre, same case size; the new one changes details.
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 UB0134101C1U1 in the title and model row and calls it a Chronomat B01 in steel and 18k red gold with a blue dial, rose gold bezel, 42mm, 200 metres and the Breitling 01 manufacture movement; the title’s word green is wrong. The photograph shows the red gold rider-tab bezel, the blue dial, the date at 4:30 and the two-tone Rouleaux bracelet. The thickness, calibre, COSC certification, reserve and last list price are Breitling’s published figures for the reference.
The dealer is Luxor Watches, a marketplace dealer, 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 Chronomats in case this one has sold.
Chronomats 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.

FAQ
Blue. The Amazon title says green, but the listing rows, the photograph and Breitling’s reference UB0134101C1U1 are all the blue dial; the green two-tone Chronomat is a different reference.
