The Navitimer RB031121/BG11/756P/R20BA.1, seen from the bench

The Breitling Navitimer RB031121/BG11/756P/R20BA.1 is the contemporary evolution of a masterpiece created in 1952. This red gold model features a 45 mm case diameter and a 24 mm lug width, housing the Breitling Caliber B03 mechanical movement with column and rattrapante chronograph function. The red gold case develops a distinctive patina over time, while the chronograph offers three counters and chronometer certification.

Frequently asked questions

What is the lug width of the Breitling Navitimer RB031121/BG11/756P/R20BA.1?

The lug width of the Breitling Navitimer RB031121/BG11/756P/R20BA.1 is 24 millimetres, measured from centre to centre of the attachment holes on the case. This specific dimension is determined by the proportion of the 45mm case and must be respected rigorously: straps with a lug width smaller than 24mm (for example 22mm) will create unwanted vertical play, whilst oversized straps will be physically incompatible with the case lugs.

Which strap is most suitable for the Breitling Navitimer RB031121/BG11/756P/R20BA.1?

For the Navitimer in rose gold, alligator leather represents the benchmark choice: its regular scale texture, natural softness and ability to develop a noble patina over time create superior aesthetic harmony with red gold. High-quality alternatives include vegetable-tanned calf for characteristic aging, shell cordovan for density and distinctive brilliance, and NATO fabric straps for a sporty approach whilst maintaining fidelity to the model's aviation heritage.

How do you change the strap on a Breitling Navitimer?

Strap replacement requires a spring bar tool (a specific implement for removing the attachment pins). Position the watch with the case facing upwards, insert the tool's blade into the small slot beneath the lug, gently push the pin inward and the strap will detach from the case. Repeat on the opposite lug, then position the new strap by aligning the holes with the case pins and press until the fastening clicks into place. If you do not have the tool, a watchmaker will perform the operation within minutes at minimal cost.

Is the strap of the Breitling Navitimer RB031121/BG11/756P/R20BA.1 compatible with other models?

The 24mm strap of the Navitimer RB031121/BG11/756P/R20BA.1 is compatible only with other Breitling models that use this same lug width. Most wristwatches utilise standard widths of 20mm, 22mm or 24mm, but not all Breitling models adopt 24mm. Before purchasing a strap for another watch, always verify the lug width by consulting the original documentation or contacting an official dealer.

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

The lifespan of a natural leather strap depends on the material and usage. High-quality alligator leather with vegetable tanning lasts on average 4-6 years with daily wear, developing characteristic patina over time. Shell cordovan, being a very dense leather, can exceed 8-10 years. Classic calf leather straps have an average lifespan of 3-5 years. Frequent exposure to water, perspiration and extreme climatic conditions reduces longevity. Regular maintenance (gentle cleaning, occasional conditioning) significantly extends strap life. Milano Straps offers straps with 18-month warranty and replacement support.
