Referenced as the AB0138211B1P1, this Breitling Navitimer B01 super clone pairs the classic slide rule bezel with a black dial on an alligator leather strap, which is a combination that shifts the Navitimer from pilot tool toward executive chronograph. At 43mm in stainless steel, the case size matches the standard Navitimer B01, but the alligator strap changes how the watch carries itself on the wrist. The black dial keeps all three chronograph sub-registers clearly defined against the dark ground, and silver-toned hands and indices provide the contrast needed for rapid time checks. Here the strap, not the dial, does all of the dressing, and the chronograph underneath stays fully functional.

A new chronograph deserves a short test on the first day: start, stop and reset it several times and watch the central seconds hand snap back to 12. The B01 pusher and reset checks in our Navitimer guide explain what to look for.

Why AB0138211B1P1 Comes on Black Alligator

The alligator strap replaces the traditional pilot bracelet with a dressier option. Breitling offers this configuration from the factory for buyers who want the slide rule functionality without the heft and industrial feel of a metal link bracelet on the wrist.

What Powers This Navitimer B01 Super Clone

The B01 designation in the Navitimer line refers to the in-house automatic chronograph caliber, which in the genuine watch provides 70 hours of power reserve (this clone Cal. B01 runs for about 55 hours) and integrates the chronograph function through a column wheel rather than a cam lever. On the genuine black-dial reference, a sapphire caseback puts the movement on show, and the clone Cal. B01 copies its column-wheel layout, which keeps the strap version interesting for anyone who enjoys mechanical detail. The rose gold Navitimer R17395211A takes the dress approach even further with a red gold finish and a smaller 35 mm case. Both sit within the Navitimer range, but they target opposite ends of the formality spectrum.

Black Dial and Black Leather, No Metal Between

Black dial on alligator leather gives this Navitimer a tonal unity that bracelet versions never quite achieve, since the dark strap frames the dark dial without any metallic interruption at the wrist. The white stitching along the strap picks up the silver of the three counters, so the watch looks finished as one piece whether it is worn at dinner or in transit.
