Frequently asked questions

What is the lug width of the Breitling Top Time AB01765A1B1A1?

The lug width of the Breitling Top Time AB01765A1B1A1 is 20mm. This measurement is taken internally between the two lugs at the point where they meet the case, and is the correct dimension to use when selecting any compatible replacement strap.

What is the best strap for the Breitling Top Time AB01765A1B1A1?

The most suitable straps for the Breitling Top Time are: alligator leather in tobacco or cognac tones for an elegant vintage register, shell cordovan for those who appreciate a developing patina over time, vulcanised rubber for everyday sporting use, and a NATO strap in nylon or leather for a look that is philologically consistent with the model's 1960s aesthetic.

How do I change the strap on the Breitling Top Time AB01765A1B1A1?

The strap is replaced using a fine-tipped or lever-type spring bar tool, inserted into the lateral slot of the spring bar securing the strap to the lug. Compress the spring bar and slide the strap out. The procedure does not require opening the case and can be completed in a few minutes with the correct tool. It is advisable to work on a soft surface to avoid scratching the case.

Is there an aftermarket strap compatible with the Breitling Top Time AB01765A1B1A1?

Yes, any strap with a 20mm attachment is compatible with the Breitling Top Time AB01765A1B1A1. The aftermarket offers a wide selection: handcrafted leather, rubber, nylon and exotic material straps. Milanostraps.it stocks a range of artisanally crafted 20mm straps compatible with this reference.

How long does a leather strap last on a Breitling Top Time?

The lifespan of a leather strap depends on the quality of the tanning and daily use. A first-grade vegetable-tanned strap, worn daily and periodically treated with nourishing cream, typically lasts between 2 and 5 years. Frequent exposure to water and perspiration accelerates deterioration; in such contexts, alternating with a rubber or NATO strap is recommended.
