Strap for Navitimer B01 Chronograph 46 Red Gold / Silver / Bracelet

The lug width (ansa measurement) of the Breitling Navitimer RB0137241G1R1 is 24mm. This measurement represents the distance between the two lugs where the strap attaches. It is essential to measure this distance accurately before purchasing an aftermarket strap using a calliper or metal ruler.

For the Red Gold 46mm RB0137241G1R1, we recommend a dark alligator (black or chestnut) for formal elegance, vegetable-tanned calf for developing patina over time, shell cordovan for material ambition, or a NATO fabric strap for sporty versatility. Your choice depends on intended use: daily and versatile call for alligator or calf; sport-chic demands NATO or FKM rubber.

You have two options for strap replacement. First is DIY: remove the lug pins (typically push-fit or screwed) using a dedicated tool, extract the old strap, insert the new one by aligning the lugs with the pins, and reinserting the pins. Second, recommended for precious Red Gold horology, is to consult a qualified watchmaker or Casati Milano to ensure precision and guarantee.

Yes, any strap in 24mm lug width is compatible with the RB0137241G1R1. Quality aftermarket straps (alligator, calf, shell cordovan, NATO, rubber) offer greater aesthetic versatility than Breitling original straps, allowing you to adapt the watch to different occasions whilst maintaining technical integrity and comfort.

A quality leather strap (alligator or calf) typically lasts 3-5 years with daily wear, developing patina that increases its character. Longevity depends on environmental humidity, frequency of use, and maintenance. A vegetable-tanned strap can last even longer due to tannin's resilience. Casati Milano's custom strap warranty covers 18 months.
