Name: Breitling Avenger Chronograph 43 A13317101B1X1
Brand: Breitling
SKU: A13317101B1X1

The Avenger Chronograph 43 is Breitling's tool-watch answer to the question nobody asked politely: what if a military chronograph had 300 meters of water resistance? Steel, large pushers, screwdown crown, and a dial engineered for legibility under pressure. Collectors drawn to purpose-built instruments will find it honest and capable; those who want a dressy chrono should look elsewhere.

What it is

Breitling introduced the current Avenger Chronograph 43 in 2019, consolidating the Avenger family under a cleaner lineup. The reference A13317101B1X1 runs the Breitling Caliber 13, a regulated ETA Valjoux 7750 with column wheel added via Breitling's own module. The 7750 base has been an industry workhorse since the 1970s and needs no defense, though Breitling markets this as an in-house-adjacent movement by virtue of the added complication layer.

The Avenger name stretches back to the 2000s Avenger Seawolf generation, and the 43mm format replaced earlier 44-45mm models as part of a sizing rationalization. A rubber-strap variant (A13317101B1W1) and a third-party strap version round out the immediate family without meaningful spec differences.

Buying notes

The Valjoux 7750 is a column-wheel movement in this spec but verify the chronograph function before buying pre-owned: worn reset hammers produce imprecise reset, and the reset cam is a known service item in high-use examples. Check the screwdown crown for threading wear; the Avenger sees more field use than most chronographs and crowns get cross-threaded. Pushers should feel crisp with a positive detent in both start/stop and reset positions, any mushiness points to a service need.

Confirm the caseback seal has not been opened by an independent shop without re-pressure-testing, particularly on examples marketed as "diver-safe" given the 300m rating. The rubber strap variants use a proprietary lug width that limits aftermarket options if you want to keep the tool-watch character.

Market read

New retail sits around $5,800-6,200 USD depending on strap configuration. Pre-owned examples in strong condition trade in the $3,800-4,800 range, with the gap between retail and secondary reflecting that the 7750-based movement does not command the premium of a fully in-house caliber. The rubber-strap variant holds value slightly better in collector circles that prioritize sport configuration.

No meaningful grey-market discount exists on current production; authorized dealer pricing is close to street pricing.

Service expectations

The Breitling Caliber 13 (Valjoux 7750 base) has a recommended service interval of five to seven years. Breitling official service for a chronograph in this family runs $600-900 USD depending on parts needed and regional service center pricing. Independent watchmakers familiar with the 7750 can service it competently for less, though re-pressure-testing to 300m after case opening requires proper equipment and should not be skipped.

Authentication

Verify all screwed-in crown and pushers thread fully; stripped threads compromise the water-resistance design.

Known issues in the market

The screwed-in pushers and crown are the water-resistance mechanism; any that will not thread down fully indicate damage.
Cal. 13 is Valjoux 7750-based; the caseback will show the characteristic 7750 rotor which is correct.

Area	What to check	What is correct	Red flag
crown	Screw-down crown thread integrity	Crown unscrew and rescrews fully with clean threads; no cross-threading or stripping	Crown that slips or does not thread down fully; indicates stripped threads requiring case service
case	Screw-in pusher integrity	Both pushers thread in and out cleanly; function correctly when depressed after unscrewing	Pushers that will not thread in fully or are stuck in the unscrewed position; water resistance is not assured
caseback	Cal. 13 Valjoux 7750 architecture	Valjoux 7750 rotor and layout through exhibition caseback; Breitling signed and finished appropriately	Movement architecture inconsistent with the 7750 family; unsigned movement

Common legitimate replacements

Screw-in crown and pusher gaskets require periodic replacement; factor into service cost.
Cal. 13 service is widely available given the Valjoux 7750 base caliber.

Authentication guide

Last reviewed June 2026

The Avenger Chronograph 43 runs the Cal. 13, which is an ETA Valjoux 7750-derived movement finished and COSC-certified by Breitling. The Avenger is the largest and most robust Breitling chronograph case, with a pronounced crown at 9 o'clock and large screw-down pushers. The 7750-based movement is well-documented and easy to verify through the caseback.

Known reproduction risks

toggle

MEDIUM

Replicas with non-screw-down pushers, crown positioned at 3 rather than 9, and movement architecture inconsistent with the ETA 7750.

Pushers that press freely without unscrewing requirement
Crown at 3 o'clock rather than the correct 9 o'clock position
Day indicator absent on a stated day/date Avenger Chrono 43
Movement through any caseback inconsistent with ETA 7750 architecture

The crown-at-9 position and screw-down pushers are the fastest case-level tells. Both can be confirmed without any tools in seconds.

Screw-down pushers

Original: The Avenger Chrono 43 pushers are screw-down for water resistance. Each pusher must be unscrewed before use and screwed back down before water exposure. On genuine examples, the pushers have a knurled grip ring and screw with positive thread engagement.

Replacement tells

Pushers that press freely without any unscrewing requirement -- screw-down pushers are the specification for this reference
Pusher knurling that is shallow or imprecise relative to the case finishing quality
Pushers that do not screw back down to a fully flush position with the case

Cal. 13 (ETA 7750 base)

Original: Cal. 13 is an ETA Valjoux 7750-derived movement finished and COSC-certified by Breitling. The 7750 has a distinctive vertical bridge layout and a large rotor. Through the caseback, the 7750 architecture is immediately recognizable to anyone familiar with the movement.

Replacement tells

Movement visible through any caseback with bridge geometry inconsistent with ETA 7750 family documentation
Rotor without Breitling branding
Power reserve substantially below 36 hours from a fully wound state
Day and date mechanism absent on an example with a stated day/date complication

Crown at 9 o'clock

Original: The Avenger has its crown at 9 o'clock, not 3, consistent with the pilot watch design brief. The crown has a Breitling logo and screws down for water resistance. A crown guard or rider-tab element protects the crown depending on the specific Avenger variant.

Replacement tells

Crown at 3 o'clock on a stated Avenger Chronograph 43 -- the 9 o'clock position is the architectural specification
Crown that does not screw down: the Avenger uses a screw-down crown as a primary seal
Crown without Breitling logo or with a logo at incorrect scale

Case back markings

toggle

2019 to present

Solid caseback with Breitling Avenger designation
Reference A13317 (or full reference string) on the case band
"Swiss Made" and COSC chronometer text
Water resistance rating: 30 ATM / 300M
Serial number between the lugs

Movement tells

toggle

Cal. 13 (ETA 7750 base) beats at 28,800bph and is COSC-certified. A significant deviation warrants service.
The 42-hour power reserve is testable. A fully wound Avenger Chrono 43 should run a minimum of 36 hours.
ETA 7750 cam-lever chronograph actuation: the pusher feel is positive but different from the column-wheel B01. Comparing the Avenger pusher feel to a Premier B01 side by side is instructive.
Day disc advance should be instantaneous at midnight. The date quickset should advance with a dedicated pusher or crown function depending on the specific variant.
Screw-down pushers should be tested for proper engagement: screw both pushers fully down, then attempt to press them without unscrewing. They must not actuate the chronograph while screwed down.
