FAQ

What is the lug width of the Breitling Navitimer RB01394A1L1P1?

The lug width of the Breitling Navitimer RB01394A1L1P1 is 14mm. This measurement should be taken with a digital calliper placed inside the lugs, against the case, to obtain the precise strap attachment width.

What is the best strap for the Breitling Navitimer RB01394A1L1P1 in Red Gold?

For the 18k red gold version, the most suitable straps are in glossy-grain alligator in burgundy or cognac tones, or in shell cordovan which develops a warm patina over time. For sportier use, vegetable-tanned calf leather or vulcanised rubber offer durability without compromising artisanal quality.

How do you change the strap on a Breitling Navitimer RB01394A1L1P1?

The strap is removed using a flat-tip or fork-style spring bar tool, applying gentle leverage on the spring bar inside the lug. Place the case on a soft cloth to avoid scratching the red gold, and proceed with care given the pronounced tapering of the Navitimer lugs.

Are there aftermarket straps compatible with the Breitling Navitimer RB01394A1L1P1?

Yes, there are aftermarket straps with a 14mm attachment that are compatible with this reference. It is essential to choose straps with shaped ends to respect the geometry of the Navitimer lugs. Milanostraps.it offers a selection of artisanal 14mm straps specifically suited to this model.

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

The lifespan of a leather strap depends on material quality and daily care. An artisanal alligator or shell cordovan strap, with regular use and proper maintenance (avoiding prolonged moisture, applying nourishing cream every 3–4 months), can last between 2 and 5 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
