It features the automatic B03 caliber with rattrapante chronograph function and chronometer certification. The case features 24mm lugs and integrates the characteristic circular slide rule for air navigation calculations.

Frequently asked questions

What is the lug width of the Breitling Navitimer RB031121.Q619.252S?

The lug width is 24mm. This dimension is specific to this Breitling reference and must match exactly the distance between the spring bars of the case. Measuring it before ordering a strap is essential to ensure absolute compatibility.

What is the best strap for the Breitling Navitimer RB031121.Q619.252S?

It depends on use and aesthetic preferences. For formal wear, an alligator in vegetable tanning—chestnut or burgundy—offers elegance without competing visually with the dial. For daily use, smooth calf with natural patina develops character over time. Shell cordovan is ideal for those who appreciate constructive texture and absolute durability. Technical rubber remains the most instrumental choice, faithful to the Navitimer's aeronautical DNA.

How do I change the strap on my Breitling Navitimer?

Remove the current strap by gently disengaging the spring bars that secure it to the case, using a dedicated tool or a blunt implement. Insert the new strap by aligning the holes with the spring bars and snap the bars into position. If uncertain, the Casati Milano atelier can perform the replacement, ensuring precision and no damage to the case.

Is an aftermarket strap compatible with the Breitling Navitimer RB031121.Q619.252S?

Yes, provided it has a lug width of exactly 24mm and is designed for watches with a 45mm diameter. Our Milano Straps are manufactured to specifications for this Breitling reference and maintain optimal visual proportions. Each strap is tested to ensure precise fit without play.

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

Durability depends on the material and use. An alligator in vegetable tanning, with proper maintenance, can last 7-10 years or more. Smooth calf maintains its integrity for 5-8 years. Shell cordovan, thanks to its exceptional density, can exceed 10 years. Technical rubber typically lasts 4-6 years before showing signs of ageing. All our straps include an 18-month warranty against manufacturing defects.
