Referenced as the AB0138211B1P1, this replica navitimer ab0138211b 43mm 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. This is the Navitimer configured for a conference room rather than a cockpit.

Technical Overview

• Case diameter: 43mm
• Case material: stainless steel
• Dial color: black with three silver sub-dials
• Bezel: bidirectional slide rule with aviation calculator scale
• Crystal: sapphire with anti-reflective coating
• Strap: black alligator leather with deployant clasp
• Movement: automatic chronograph

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.

Inside the Movement

The B01 designation in the Navitimer line refers to the in-house automatic chronograph caliber, which provides roughly 70 hours of power reserve and integrates the chronograph function through a column wheel rather than a cam lever. On this black-dial reference, the transparent caseback reveals the decorated movement, making the strap version doubly appealing for anyone who enjoys mechanical detail. The rose gold Navitimer R17395211A takes the dress approach even further with precious metal and a smaller case. Both sit within the Navitimer range, but they target opposite ends of the formality spectrum.

What Sets It Apart

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. This replica navitimer ab0138211b 43mm is the variant to consider when a chronograph needs to work as hard at dinner as it does in transit.
