Frequently asked questions

What is the lug width of the Breitling Navitimer A17325241B1A1?

The Breitling Navitimer A17325241B1A1 has a lug width of 20mm. This measurement should be verified using a digital calliper between the two lugs at the strap attachment point. Any strap with a 20mm width is compatible with this reference.

What is the best strap for the Breitling Navitimer A17325241B1A1?

For the 38mm Navitimer, a polished alligator strap enhances the contrast between the instrument dial and the steel case. Vegetable-tanned calf leather develops a patina that complements the brushed steel over time. For sporting use or humid environments, vulcanised rubber or ballistic nylon NATO straps are the most practical choices.

How do you change the strap on a Breitling Navitimer A17325241B1A1?

The strap is removed using a flat-tipped or fork-type spring bar tool. The spring bars are of standard diameter; it is advisable to protect the lugs with a soft cloth during the operation to avoid scratching the steel finish. The new 20mm strap is fitted by pressing the spring bars into position.

Are there aftermarket straps compatible with the Breitling Navitimer A17325241B1A1?

Yes. Any strap measuring 20mm at the lug is compatible with the Navitimer A17325241B1A1. Casati Milano handcrafted straps are made to measure using selected leathers and offer a construction quality that surpasses standard straps, with an 18-month warranty against manufacturing defects.

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

A quality handcrafted leather strap — alligator, vegetable-tanned calf or shell cordovan — typically lasts between two and five years with daily wear, depending on exposure to perspiration and moisture. Regular conditioning with a leather cream and alternating with a second strap will significantly extend the life of the leather.
