BLS Factory Breitling Super Chronomat 44mm – B01 Chronograph Guide
The BLS Factory Breitling Super Chronomat brings the bold Chronomat design into a 44mm chronograph configuration, combining a stainless-steel case, ceramic exterior details and a B01-style automatic chronograph movement.
At 44mm, this is not intended to be a particularly discreet watch. The larger case, rotating bezel and chronograph layout give it a noticeably stronger wrist presence than more compact everyday models.
Beyond the size, there are several details worth looking at more closely, particularly the ceramic components, bezel operation, screw-down crown, chronograph functions and double-sided anti-reflective sapphire crystal.
44mm Case
The supplied specifications identify this Super Chronomat as a 44mm configuration.
That larger diameter suits the overall design because the dial needs enough space to accommodate the chronograph registers, hour markers and other functional elements without making the display feel overly compressed.
For anyone considering a 44mm watch, diameter is only part of the fit.
Case thickness, lug profile, bracelet or strap configuration and total weight can all affect how large the watch actually feels on the wrist.
Those measurements are particularly useful when an individual watch is available for physical testing.
Stainless-Steel Case
The main case uses stainless-steel construction with a screw-down caseback.
The Chronomat design combines relatively substantial case geometry with contrasting surface finishes, so the transition between brushed and polished areas is worth looking at from different angles.
Case edges, crown guards, pushers and the transition into the bezel are particularly noticeable on a watch of this size.
Ceramic Details
Ceramic is one of the more visually distinctive elements of this BLS release.
Rather than treating “ceramic technology” itself as an indication of quality, it is more useful to look at how the ceramic components are actually finished and fitted to the watch.
Useful details include surface consistency, edges, alignment and the transition between ceramic and adjacent metal components.
Ceramic can also react differently to light than polished or brushed steel, so neutral lighting gives a better impression of the actual surface appearance.
Ratcheting Unidirectional Bezel
The watch uses a ratcheting unidirectional rotating bezel.
This is one of the parts that is worth physically operating rather than judging only from photographs.
Rotation should feel consistent through the available positions, with clear engagement and no unusual looseness.
After rotation, the bezel markings should also be checked for alignment against the dial.
On a large 44mm sports chronograph, bezel feel can make a noticeable difference to the overall impression of the watch.
B01-Style Automatic Chronograph Movement
Inside is a B01-style automatic mechanical chronograph movement.
The supplied information does not clearly establish the underlying base caliber or internal construction, so it is better to identify the movement by its supplied B01-style configuration rather than assume a specific architecture.
What matters most in everyday use is whether the movement and chronograph functions operate correctly.
The chronograph should be tested through a complete sequence:
Start → Run → Stop → Reset
The central chronograph seconds hand should operate normally, while the corresponding chronograph registers should be observed during an extended running test.
After reset, the chronograph hands should return correctly to their starting positions.
Chronograph Pushers
A chronograph should not be judged only by whether the seconds hand moves.
Pusher operation also matters.
Start, stop and reset should feel consistent, without unusually heavy or irregular resistance. Repeating the sequence several times provides a much better indication of operation than testing it only once.
If the chronograph includes longer-duration timing registers, allowing it to run for an extended period is also useful for confirming that the complete mechanism is functioning.
Screw-Down Crown
The watch uses a screw-down crown with a double-gasket construction, according to the supplied specifications.
The crown should screw and unscrew smoothly and engage the movement-setting positions correctly.
Manual winding and time setting should also operate normally.
Although the crown and gasket construction are relevant design details, they should not be used by themselves to promise a specific level of water resistance. Actual water resistance requires separate pressure testing.
Domed Sapphire Crystal
The front uses a domed sapphire crystal with double-sided anti-reflective treatment.
This is particularly useful on a large chronograph dial because reflections can otherwise interfere with the visibility of the hands, markers and subdials.
The curved profile also changes how the dial appears when viewed from an angle.
Under strong lighting, the crystal can be checked for optical distortion, coating consistency and reflections across different viewing angles.
Dial and Chronograph Layout
The dial follows the instrument-inspired character associated with Breitling sports chronographs.
Because several pieces of information are displayed simultaneously, alignment becomes particularly important.
Useful areas to look at include:
- Hour markers
- Main hands
- Chronograph hands
- Subdial alignment
- Printing
- Date display, where applicable
- Bezel-to-dial alignment
A straight front-facing photograph is useful for alignment, while angled and macro photographs are better for evaluating the depth and finishing of individual components.
A Larger Sports Chronograph on the Wrist
The Super Chronomat 44mm is designed around a substantial sports-watch profile.
For someone who likes larger chronographs, the 44mm case provides the kind of presence expected from this design.
For smaller wrists, however, actual case thickness and lug-to-lug fit become more important than the 44mm diameter alone.
Weight is another useful measurement, particularly when comparing different steel, ceramic, bracelet and strap configurations.
Super Clone Watch and Actual Performance
The term super clone watch is often used when discussing higher-level replica chronographs, but it does not tell us how an individual movement is actually performing.
With a mechanical chronograph, functional testing is particularly important because there are more moving components and operating functions than on a simple three-hand watch.
Actual daily rate, amplitude, beat error and beat rate, together with a complete chronograph test, provide much more useful information.
For actual movement measurements and physical dimensions from an individual example, see our BLS Factory Breitling Super Chronomat 44mm QC test.
Details Worth Checking
For an individual BLS Super Chronomat 44mm, we would first check the actual case dimensions and weight because these figures are particularly relevant on a larger sports chronograph.
The bezel should rotate consistently and align correctly after operation.
The crown and chronograph pushers should then be tested individually, followed by several complete start, stop and reset cycles.
Movement testing can record daily rate, amplitude, beat error and beat rate.
On the exterior, useful areas include the ceramic components, crystal, dial alignment, case finishing, bracelet or strap attachment and clasp operation.

Frequently Asked Questions
- What size is the BLS Factory Breitling Super Chronomat?
This version uses a 44mm case, giving it a relatively substantial sports-chronograph presence on the wrist.
- What movement does the BLS Super Chronomat use?
The supplied specifications identify a B01-style automatic mechanical chronograph movement. The information provided does not clearly establish the underlying base caliber, so it is better not to assume a specific internal architecture.
- Does the chronograph work?
The supplied configuration uses a functional mechanical chronograph. An individual watch should still be tested through multiple start, stop and reset cycles, including an extended running test where possible.
- What type of crystal does it use?
It uses a domed sapphire crystal with double-sided anti-reflective treatment, according to the supplied specifications.
- Is the bezel functional?
Yes. The supplied configuration uses a ratcheting unidirectional rotating bezel. Rotation feel, play and final alignment are useful points to check on an individual watch.
- Does the screw-down crown mean the watch is waterproof?
Not by itself. A screw-down crown and gasket system are useful parts of the case construction, but actual water resistance should only be confirmed through appropriate pressure testing.
