The Navitimer AB0137241L1A1, seen from the bench

The Breitling Navitimer AB0137241L1A1 is a chronograph with roots in civil and military aviation history, originally introduced in 1952 for the AOPA. This stainless steel 46mm model features the B01 manufacture caliber, certified as a chronometer with column escapement and 28,800 vph frequency, offering 70-hour power reserve. The black dial displays the classic tri-compax layout with three counters, fixed bezel with tachymetric scale, and date window at 3 o'clock. The 24mm lug width is a structural requirement for correct visual proportions on this case size.

Frequently asked questions

What is the lug width of the Breitling Navitimer AB0137241L1A1?

The Breitling Navitimer AB0137241L1A1 features a 24mm lug width. This is a non-standard measurement compared to the more common 20mm or 22mm, typical of the 46mm Navitimer variants. It is essential to verify this dimension with a digital calliper before purchasing an aftermarket strap.

What is the best strap for the Breitling Navitimer AB0137241L1A1?

The most suitable materials for the Navitimer AB0137241L1A1 are vegetable-tanned alligator leather for an elegant and structured pairing, shell cordovan for those seeking depth and patina over time, a NATO nylon strap for an authentic aeronautical aesthetic, and vulcanised rubber for sporting use. The correct attachment width is 24mm.

How do you change the strap on a Breitling Navitimer AB0137241L1A1?

Strap replacement is carried out via the standard 24mm spring bars seated in the case lugs. It is advisable to use a flat-blade watchmaker's screwdriver or a dedicated spring bar tool to avoid scratching the polished steel surfaces. Alternatively, Casati Milano offers a fitting service in the atelier by appointment.

Are there aftermarket straps compatible with the Breitling Navitimer AB0137241L1A1?

Yes. The Navitimer AB0137241L1A1 accepts any strap with a standard 24mm spring bar attachment. MilanoStraps offers a dedicated selection of 24mm straps in various materials and finishes, with deployant clasp or pin buckle options. For a bespoke solution, Casati Milano crafts made-to-measure straps with leather selected directly in the atelier.

How long does a leather strap last on a Breitling Navitimer AB0137241L1A1?

The lifespan of a leather strap depends on the material, care, and usage. A quality vegetable-tanned alligator strap, treated with neutral wax and kept away from water and excessive perspiration, can last between 3 and 7 years while retaining structural integrity and appearance. Shell cordovan tends to last even longer due to the density of its fibres. MilanoStraps provides an 18-month warranty against manufacturing defects on all straps.
