Strap for Navitimer B01 Chronograph 43 Stainless Steel / Green / Spain

The Breitling Navitimer AB01385A1L1P1 features a 22mm lug width. This measurement can be verified using a digital calliper positioned between the two lugs at the narrowest point beneath the case. Any standard aftermarket strap with 22mm spring bars will be fully compatible with this reference.

For the Navitimer AB01385A1L1P1 in stainless steel at 43mm, a vegetable-tanned alligator leather strap is the most coherent choice: the regular scale grain echoes the logarithmic slide rule without competing with it. A smooth European calf strap suits formal wear, while a nylon NATO references the instrument's aeronautical heritage in casual settings. Vulcanised rubber is the preferred option for humid or active environments.

Replacing the strap on the Navitimer AB01385A1L1P1 requires a springbar tool — either a lever-tip or a pointed-tip model. Insert the tip into the lateral groove of the lug, compress the spring bar and slide the strap free. The operation takes only a few seconds and requires no professional equipment, though working on a soft surface is advisable to avoid scratching the stainless steel case.

Yes. The Navitimer AB01385A1L1P1 uses straight standard 22mm lugs, compatible with the vast majority of quality aftermarket straps available on the market. Milano Straps offers a curated selection of handcrafted leather, NATO, and rubber straps in 22mm, produced with selected materials and Italian craftsmanship. For a bespoke fit, the Casati Milano atelier service is available by appointment.

The lifespan of a leather strap depends primarily on tanning quality and daily use. A vegetable-tanned strap made from full-grain leather, worn regularly but kept away from aggressive environments (high humidity, direct sunlight), will typically last 2–4 years while retaining its aesthetic and structural integrity. Shell cordovan and dense vegetable leathers tend to outlast softer alternatives due to their compact fibre structure. Milano Straps provides an 18-month guarantee against manufacturing defects on all its straps.
