Frequently asked questions

What is the lug width of the Breitling Navitimer AB0121A11B1A1?

The Breitling Navitimer AB0121A11B1A1 has a lug width of 22mm. This measurement is taken with a millimetre calliper positioned between the two lower lugs of the case. Any strap with a 22mm attachment will be compatible with this reference.

What is the best strap for the Breitling Navitimer AB0121A11B1A1?

For the Navitimer AB0121A11B1A1 in 43mm stainless steel, the most suitable options are: flat-scaled alligator in black or navy for formal use, vegetable-tanned calf leather in tobacco brown for everyday wear with authentic patina, NATO nylon for consistency with the aeronautical DNA, and vulcanised rubber for sporting contexts. A brushed steel deployant clasp is recommended to distribute pressure evenly across the strap and reduce wear at the centre hole.

How do you change the strap on the Breitling Navitimer AB0121A11B1A1?

To replace the strap on the Navitimer AB0121A11B1A1, a spring bar tool or lever-type screwdriver is required. The 22mm spring bars are removed by applying gentle pressure at the end in contact with the lug. It is advisable to work on a soft surface to avoid scratching the case. Alternatively, any watchmaker or specialist atelier can carry out the procedure in a matter of minutes.

Are there aftermarket straps compatible with the Breitling Navitimer AB0121A11B1A1?

Yes. Any strap with a 22mm attachment is geometrically compatible with the Navitimer AB0121A11B1A1. The standard length for a chronograph of this diameter is 130/80mm. It is important to ensure the strap has an appropriate thickness for the short lugs of the Navitimer, generally between 3.5 and 5mm at the attachment point. Milano Straps offers a selection of handcrafted 22mm straps specifically dimensioned for chronographs in this category.

How long does a leather strap last on a Breitling Navitimer AB0121A11B1A1?

The lifespan of a leather strap depends on the type of leather, frequency of use, and exposure to perspiration and moisture. A quality vegetable-tanned calf strap, with daily use and regular conditioning, typically lasts 18 to 36 months. A high-quality alligator strap can exceed 5 years with proper care. Alligator and shell cordovan are the most durable leathers due to their dense fibrous structure. Milano Straps provides an 18-month guarantee against manufacturing defects on all handcrafted straps.
