Breitling Super AVI B04 Chronograph GMT 46 P-51 Mustang RB04451A1B1X1: Red Gold Guide

The Breitling Super AVI B04 Chronograph GMT 46 P-51 Mustang in 18 ct red gold, reference RB04451A1B1X1, is a 46 mm pilot's chronograph with a second time zone, a grey Arabic-numeral dial and a leather strap, built as a tribute to the North American P-51 Mustang fighter. Breitling's own naming varies between "Super AVI" and "Classic AVI" depending on the page, and our catalogue entry carries both words. This guide covers the specifications, what the Mustang tribute refers to, what a chronograph with GMT does, how the red gold case compares with the steel version, how a 46 mm case wears, dated catalogue prices from October 2026 and what to check before buying. Bizak & Co. sources the RB04451A1B1X1 to order; the Breitling collection lists the configurations we can seek.

What does the P-51 Mustang tribute refer to?

The North American P-51 Mustang first flew in 1940 and became one of the best-known long-range escort fighters of the Second World War, fitted with a Rolls-Royce Merlin engine in its best-known versions. Breitling has a long aviation history of its own, from onboard cockpit chronographs in the 1930s to the Navitimer of 1952, and the AVI watches draw on that. The Mustang model borrows the look of mid-century cockpit instruments: Arabic numerals, a legible dial and a bold case. The red gold version turns that tool-watch language into a luxury object, and is the loudest expression of the idea.

What does a chronograph with GMT actually do?

The chronograph times events with a start, stop and reset, through the central seconds hand and subdials. The GMT hand tracks a second time zone against a 24-hour scale, so you can read home time while the main hands show local time. Having both on one dial is what made the B04 a favourite of pilots and frequent travellers: you can time a flight leg and keep home time without taking the watch off. The combination also makes the dial busy, and the grey Arabic dial of the RB04451A1B1X1 is chosen to keep it readable.

Red gold or steel: how does the Mustang compare?

The two share the same movement family and case size, so you are paying the premium for the gold case and the dial colour, not for a different watch inside. If you want to use the chronograph and GMT daily and not worry about the case, the steel version is the sensible choice. If you want the same watch as a piece of jewellery, the red gold version is what the reference exists for.

How does a 46 mm red gold case wear?

A 46 mm case is at the top of what most wrists will carry, and the gold makes it heavier than its size suggests. On a wrist under about 17 cm (6.7 inches) the lugs may overhang, and the leather strap is a sensible partner because it distributes the weight better than a gold bracelet. Try it before you commit. A chronograph with GMT is a thick mechanism, so check that the case passes under your shirt cuff.

How much is the Breitling RB04451A1B1X1? Prices in 2026

• Retail. Breitling publishes recommended prices on its own site and through authorised retailers, and limited-edition gold references are often allocated rather than freely sold. Check the current figure on the Breitling product page linked above or with an authorised retailer.
• Bizak catalogue ask. On 1 October 2026 our sourced catalogue listed the red gold RB04451A1B1X1 at US$23,175 brand new, full set, and the steel AB04453A1B1X1 at US$8,475 brand new, both sourced to order.
• What moves the price. Full set with the edition card, a clean unworn case with protective film, and a recent warranty date each add. A watch sold without its card or with signs of try-on handling should be priced lower.

Those figures describe what we saw and will move. Ask for a dated quote for the exact watch and set; our Rolex price guide explains the method we use to compare quotes across brands.

Is a gold Breitling a good investment?

Breitling gold chronographs are bought for what they are, not as stores of value, and the secondary market for them is narrower than for a gold Rolex or Patek. A limited edition with a clear story, the Mustang here, helps, but it does not guarantee that a resale will return the purchase price. Buy it because you want a gold pilot chronograph. If resale matters, ask for a written cash-buy assessment before you commit.

Buying a brand-new RB04451A1B1X1: what to check

• Edition and serial. The reference and a serial number should be on the case back and match the Breitling card. If the watch is a numbered edition, the number should match the card.
• Full set. Box, outer packaging, warranty card, manuals and any edition booklet. Check the serial on the card against the case.
• Protective film and handling. Film on the case back or crystal is a good sign for an unworn watch; drag marks on the red gold, bezel or lugs suggest try-on.
• Chronograph test. Start, stop and reset: the pushers should click firmly and the chronograph hand should return exactly to the 12 position.
• GMT hand. The GMT hand should move independently of the main hands and show the second time zone cleanly; ask for a demonstration of how it is set.
• Strap and clasp. The leather should be unmarked and the buckle signed and in matching red gold; check the strap lugs for scratches.
• Price against the band. A brand-new red gold Mustang offered far below the catalogue range needs a clear explanation of its source.

Servicing and care

Breitling services its own watches through its boutiques and service centres, and chronographs with GMT are more complex to service than time-only watches, so budget for it and keep the service paperwork. Gold cases do not corrode, but they mark easily, so keep it in the box when not worn and avoid rubbing it against metal surfaces. Leather straps dislike water; for swimming use a rubber or textile strap rather than the leather.
