Frequently asked questions

What is the lug width of the Breitling Navitimer AB01219A1G1A1?

The lug width of the Breitling Navitimer AB01219A1G1A1 is 20 mm. This measurement is taken with a calliper between the two lugs at the inner edge of the case, and is the key parameter for identifying compatible straps in leather, NATO nylon or rubber.

What is the best strap for the Breitling Navitimer AB01219A1G1A1?

For the Navitimer AB01219A1G1A1 with blue dial, straps in vegetable-tanned alligator leather (Hornback grain, navy blue or cognac) offer the best balance between instrumental readability and elegance. Shell cordovan suits those who appreciate a developing patina over time, while a ballistic nylon NATO is preferred for intensive daily use or travel.

How do you change the strap on a Breitling Navitimer?

The strap is replaced by removing the 20 mm spring bars using a flat-tipped springbar tool inserted into the lug slot. The operation does not require opening the case or professional watchmaking tools, but it is advisable to work on a soft surface to prevent scratches to the case or crystal.

Are there aftermarket straps compatible with the Breitling Navitimer AB01219A1G1A1?

Yes. Any strap with a 20 mm attachment is technically compatible with the Navitimer AB01219A1G1A1. It is important to verify that the attachment end follows the pronounced downward curvature of the Navitimer lugs. Milanostraps.it offers a selection of handcrafted 20 mm straps, with bespoke customisation available through the Casati Milano atelier.

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

The lifespan of a leather strap depends on the material and usage. A high-quality vegetable-tanned alligator strap, with regular care (leather conditioning, avoiding prolonged exposure to moisture and perspiration), typically lasts between 3 and 5 years with daily wear. Shell cordovan is structurally more resilient and can exceed 5 years. Casati Milano offers an 18-month guarantee against manufacturing defects.
