Strap for Navitimer 1 B01 Chronograph 46 Red Gold / Silver / Croco / Folding

The lug width of the Breitling Navitimer RB0127121G1P2 is 24 mm, measured between the two centre pins that attach the case to the strap. This dimension is specific to this model and must be strictly observed when selecting aftermarket straps.

For the Navitimer RB0127121G1P2 in Red Gold, cognac or dark brown alligator straps are recommended (for chromatic harmony), vegetable-tanned calf leather in dark tones (for virtuous ageing), or shell cordovan for those seeking structural rigidity and natural brilliance. A NATO strap offers aviation authenticity, whilst vulcanised rubber is ideal for intensive use.

The strap is changed by removing the spring bars (the small metal pins at the strap ends) using a dedicated tool. Position the spring bar removal tool on one pin, lift gently and remove; repeat on the other side. Insert the new strap by aligning the holes with the lugs, then reinsert the spring bars until they click into place. Verify the fixing before wearing the watch.

Yes, provided the strap is marked for 24mm lug width. Verify that the strap thickness is not excessive (maximum 4–5 mm) to ensure correct spring bar insertion and case closure. Milano Straps are specifically engineered for this width and guarantee full compatibility with your Navitimer.

A high-quality leather strap (alligator, calf or shell cordovan) typically lasts 3–5 years with moderate daily wear, up to 7–8 years with occasional use. Durability depends on environmental humidity, frequency of wear and care. The Milano Straps warranty is 18 months; regular maintenance and preventative treatment with natural oils significantly extends strap life.
