Reference AB0138241G1P1 presents the Navitimer B01 chronograph with a silver dial and alligator leather strap at 43mm, and this Breitling Navitimer B01 clone follows that configuration closely, black alligator included. The silver sunburst surface with contrasting sub-dials gives this variant a distinctly dressy character compared to the darker-dial Navitimers in the range. Pairing the 43mm chronograph case with alligator rather than a steel bracelet also changes the weight and feel on the wrist noticeably.

On a panda dial the three black counters are the first thing the eye lands on, so their spacing and centring are easy to judge; our guide’s QC list includes a sub-dial alignment check for exactly that.

Panda Layout and the AOPA Wings at 12

The silver dial combined with black sub-dial registers creates a panda layout that provides strong legibility. The AOPA twin-wings emblem at 12 and the date aperture at 6 anchor the vertical axis of the dial in a balanced composition.

Navitimer B01 Clone Calibre and Why the Strap Matters

Under the case back, the clone Cal. B01 provides column-wheel chronograph operation and about 55 hours of power reserve, against 70 hours for the genuine B01. This is the same movement found in every 43mm Navitimer B01 reference in the range, whether on a steel bracelet or a leather strap. What distinguishes this particular configuration is the strap choice: alligator leather pairs the mechanical seriousness of a column-wheel chronograph with a texture that suits blazers and formal settings. The AB0138241L1A1 green version on bracelet offers the same internal specifications but takes the watch in a completely different visual direction.

Silver Dial and Black Alligator Together

Silver dials have always carried a more traditional, almost vintage sensibility in the chronograph world. On the Navitimer, that effect is amplified by the slide rule bezel and the leather strap, both of which nod toward the collection’s 1950s origins. A single Navitimer that has to cover work days, travel and evenings out is well served by this silver-and-leather setup. The overall impression is one of technical capability wrapped in dressy packaging. The steel folding clasp helps the strap last, too: the leather is not bent at the same hole every morning, so the alligator keeps its shape for longer.
