BLS Factory Breitling Avenger Chronograph 44mm Automatic Watch
The BLS Factory Breitling Avenger Chronograph combines a 44mm stainless steel case with a 7750 automatic mechanical chronograph movement, date display and unidirectional ratcheting bezel.
With a supplied case thickness of 15mm, this configuration has a substantial profile suited to its mechanical chronograph architecture.
Additional details include a screw-down crown with a double-gasket structure, engraved bezel markings and an Italian cow-leather strap fitted with a folding-style clasp.
44mm Stainless Steel Case
The watch features a 44mm stainless steel case, creating a substantial sports-watch profile.
The larger case provides sufficient space for the chronograph indications, date display and primary time functions without requiring these elements to be compressed into a smaller dial.
Stainless steel also provides a durable exterior material suitable for the functional character of the Avenger collection.
15mm Case Thickness
The supplied case thickness is 15mm, giving the watch overall dimensions of 44 × 15mm.
The additional thickness compared with a conventional three-hand automatic watch accommodates the more complex chronograph movement architecture.
Together, the 44mm diameter and 15mm thickness create a substantial wrist presence.
Actual wearing comfort will depend on individual wrist circumference and personal preference.
7750 Automatic Chronograph Movement
This BLS Factory Avenger Chronograph uses a 7750 automatic mechanical chronograph movement.
The movement combines conventional timekeeping with mechanical stopwatch functions while retaining an automatic winding system.
Normal wrist movement contributes to replenishing the movement’s stored energy during regular wear.
Because the supplied information identifies the underlying movement as a 7750, this page does not describe it as an original Breitling B01 movement.
Mechanical Chronograph Function
The watch incorporates a mechanical chronograph function for measuring elapsed time.
Unlike a conventional three-hand automatic watch, the chronograph movement contains additional components responsible for starting, stopping and resetting the timing mechanism.
The chronograph should be operated using its designated pushers and should never be forced if unusual mechanical resistance is encountered.
No specific chronograph subdial layout was provided, so unconfirmed counter positions are not added.
Date Display
In addition to the primary time and chronograph indications, the watch incorporates a date display.
The calendar mechanism advances the numerical date as part of the movement’s normal operation.
When manually correcting the date, avoid forcing the mechanism if resistance is felt.
Because the exact date-window position was not included in the supplied information, no unverified dial position is specified.
Unidirectional Ratcheting Bezel
The case incorporates a unidirectional ratcheting rotating bezel.
Numerical markers and graduations are engraved around the bezel to provide a straightforward elapsed-time reference.
This allows the bezel to operate independently from the mechanical chronograph.
The wearer therefore has both a rotating bezel reference and the dedicated mechanical chronograph available for different timing requirements.
Engraved Bezel Scale
The bezel incorporates engraved numerals and graduations.
These markings provide clear reference points when the bezel is aligned with the minute hand.
Their recessed construction also introduces additional surface detail around the exterior of the watch without requiring another timing scale directly on the dial.
Screw-Down Crown
The watch is fitted with a screw-down crown, providing a threaded connection between the crown and case.
When properly secured, this construction helps maintain the sealing structure around the crown opening.
The crown should be threaded carefully to avoid cross-threading.
After adjusting the watch, make sure the crown is returned to its fully secured position.
Double-Gasket Crown Structure
The supplied configuration specifies a double-gasket sealing structure around the crown.
These seals are intended to provide additional protection against moisture entering through the crown assembly.
However, gaskets can deteriorate with age, temperature changes and repeated crown operation.
No specific tested water-resistance depth was provided, so an unverified depth rating is not added.
Italian Cow-Leather Strap
This configuration is paired with an Italian cow-leather strap.
The leather construction provides a softer wrist feel than a full stainless steel bracelet while visually contrasting with the substantial 44mm steel case.
Leather should be protected from prolonged exposure to water, excessive perspiration, cosmetics and aggressive cleaning products.
If the strap becomes damp, allow it to dry naturally away from direct heat.
Folding-Style Clasp
The supplied strap incorporates a folding-style clasp.
Unlike a conventional pin buckle, the folding structure keeps the strap connected when opened and can reduce repeated bending around the fastening area.
The clasp and strap attachment points should be inspected periodically for looseness or excessive wear.

Chronograph and Bezel Timing
This configuration provides two different elapsed-time references.
The 7750 movement operates the mechanical chronograph, allowing elapsed time to be started, stopped and reset through the chronograph controls.
Separately, the unidirectional rotating bezel can be aligned with the minute hand to provide a simpler visual elapsed-time reference.
The two systems operate independently, making the bezel useful without requiring the mechanical chronograph to remain running.
Wearing and Care Advice
Protect the 7750 automatic chronograph movement from heavy impacts and strong magnetic fields.
Operate the chronograph pushers normally and avoid forcing them if unusual resistance is encountered.
After adjusting the time or date, ensure the screw-down crown is properly secured.
Keep the Italian cow-leather strap away from prolonged water exposure.
Although the crown uses a double-gasket structure, no specific tested water-resistance depth was supplied. Professional pressure testing is recommended before swimming or intentional water exposure.
