Breitling’s Chronomat B01 Chronograph 44, reference AB0115101F1A1, pairs a gray dial and stainless-steel pilot bracelet with a 44 mm steel case, a Manufacture Caliber 01 movement and a stated 500 m water-resistance rating. Those details describe the watch on paper; the available product information does not establish how it wears or operates in person, so this is a specification-led look rather than a firsthand review.
Which Chronomat B01 Chronograph 44 is this?
The reference is AB0115101F1A1: a stainless-steel model with a gray dial and stainless-steel pilot bracelet. Breitling presents it as a “new interpretation” and describes a satin-brushed steel case on a steel pilot’s bracelet. The product listing does not identify what changed from an earlier version, so the redesign cannot be assessed as a before-and-after comparison from that description alone.
Breitling’s official listing for reference AB0115101F1A1 is the source for the specifications below.
How large is the 44 mm case?
Breitling lists a 44 mm case diameter, 16.94 mm thickness and 22 mm lug width. The height is a notable consideration for anyone choosing a watch to fit beneath a shirt cuff; diameter alone does not tell the whole fit story. Actual wrist presence and comfort cannot be determined from these measurements without trying the watch on.

What are the dial and case details?
The satin-brushed stainless-steel case frames a gray dial with contrasting chronograph counters. The layout includes small seconds, a 30-minute counter, a 12-hour counter and a date window at 4:30. A convex sapphire crystal is glareproofed on both sides, according to Breitling. Those are manufacturer descriptions; they do not establish how legible the dial is in different lighting or how the finishing looks in person.
What does the Caliber 01 offer?
The watch uses Breitling’s self-winding Manufacture Caliber 01, which the company lists as COSC-certified. Its stated power reserve is approximately 70 hours, with a frequency of 28,800 vibrations per hour and 47 jewels. The chronograph measures 1/4 seconds and uses 30-minute and 12-hour counters.

- Cambered sapphire, glareproofed both sides
- Signature 'Rouleaux” bracelet
- Power reserve approx. 70 hrs
- Watch movement type: Breitling 01 (Manufacture) automatic-self-wind
- Band color: silver and gold
A roughly 70-hour reserve can allow the watch to sit unused over a weekend and still be running, depending on when it was last fully wound and how it is used. The figure is Breitling’s specification, not an independent measurement of this individual watch.
What are its water-resistance and control specifications?
Breitling specifies water resistance of 50 bar, equivalent to 500 m or 1,650 ft. The watch also has a unidirectional ratcheted bezel and a screw-locked crown with two gaskets. These are substantial published specifications, but water resistance is not a substitute for following the manufacturer’s care and use guidance; the listing alone does not establish the condition of any particular watch or its seals over time.

What remains unknown without a firsthand review?
The official listing establishes materials, dimensions and movement specifications, but not wrist fit, bracelet or clasp comfort, finishing under changing light, dial legibility in practice, or the feel of operating the chronograph and bezel. It also does not provide a sourced change list against a prior Chronomat B01 Chronograph 44. Current price and availability depend on market and listing status and are not established by the product specifications cited here.
Breitling states that the watch comes with a five-year international warranty and that online registration may extend coverage by up to three years. Warranty duration and eligibility can depend on applicable terms and market, so check the conditions that apply where the watch is purchased.
