TAG Heuer · Carrera Chronograph 44 · TH20-00 / Heuer 02 · blue · bracelet · on Amazon
The blue Carrera. Ceramic bezel, in-house calibre, list price.
This is the blue version of TAG Heuer’s 44mm sport Carrera with the in-house calibre: reference CBN2A1A.BA0643, a fine-brushed and polished steel case with a blue ceramic tachymeter bezel, a blue sunray dial with three counters, a date at six and HEUER 02 80 HOURS at the bottom, on the steel bracelet with a fine-brushed push-button folding clasp. Inside is the TH20-00, TAG Heuer’s column-wheel automatic chronograph sold as the Heuer 02, with about 80 hours of reserve; 100 metres. Listed at TAG Heuer’s own price when we read it, from a marketplace dealer; two Amazon ratings average 2.8 and the copy says so.

Blue on blue, and the two ratings
The Carrera is Heuer’s racing chronograph of 1963, designed by Jack Heuer for drivers who needed to read a chronograph at a glance: a clean dial, big counters and the minute track pushed out to the flange so nothing gets in the way. TAG Heuer has made it in every size and movement since, and the current line splits into the 44mm sport chronographs with the tachymeter bezel and the smaller glassbox watches that look back at the 1960s.
The blue ceramic bezel matched to a blue sunray dial is the sport Carrera’s most photographed combination, and this is the version with the in-house TH20-00 rather than the Calibre 16, so the chronograph starts without a stutter and the watch runs about 80 hours off the wrist. It is listed at TAG Heuer’s own price, not under it, which is unusual on this page. The two Amazon ratings average 2.8 stars; two reviews are not a verdict on the watch, but read them before buying and ask the dealer about condition and the card.

Reading the listing
The listing carries the reference CBN2A1A.BA0643 in the title and model row and calls it a 44mm automatic chronograph with 100 metres, a blue dial and a steel bracelet; its 18mm thickness row is not TAG Heuer’s figure. The photograph shows the blue ceramic tachymeter bezel, the three counters, the date at six and the bracelet. The calibre, reserve, bezel material, dial, bracelet, clasp and list price are TAG Heuer’s published specifications for the reference.
The dealer is World Of Watches, a marketplace dealer, and the rows we read do not state whether the watch is new with TAG Heuer’s 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 Carreras in case this one has sold.
Carreras 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.
