The Heritage

The Navitimer B01 Chronograph 41 Red Gold (ref. RB0139211G1R1) features a 41mm red gold case housing Breitling's Caliber B01, a COSC-certified automatic movement with column wheel chronograph delivering ±2 seconds per day accuracy and 70-hour power reserve. The dial displays small seconds at 9 o'clock, date, and chronograph functions with hours, minutes and seconds counters. Lug width is 14mm, requiring careful strap selection as this size differs from standard aftermarket options.

FAQ

What is the lug width of the Breitling Navitimer RB0139211G1R1?

The lug width of the Breitling Navitimer RB0139211G1R1 is 14mm. This is a less common size compared to mainstream standards. To avoid purchasing errors, it is recommended to verify the measurement using a digital calliper, measuring the internal distance between both lugs before selecting an aftermarket strap.

What is the best strap for the Breitling Navitimer in red gold?

For the Navitimer in 18k red gold, a vegetable-tanned alligator strap in dark chocolate brown or cognac offers the most coherent pairing with the watch's haute horlogerie character. Shell cordovan is a refined alternative for those seeking a strap that develops a personal patina over time. For more dynamic use, a two-tone NATO strap maintains the connection to the model's aviation heritage.

How do you change the strap on the Breitling Navitimer RB0139211G1R1?

The strap is removed using a spring bar tool, sliding the spring bars inward from the lug channel. Care should be taken to protect the red gold case from scratches — placing low-tack tape or soft cloth over the lugs before operating the tool is advisable. With 14mm lugs, it is essential to use straps fitted with spring bars of standard diameter.

Are there aftermarket straps compatible with the Navitimer RB0139211G1R1?

Yes. Milanostraps.it offers a curated selection of aftermarket straps with a 14mm attachment compatible with the Breitling Navitimer RB0139211G1R1. Available materials include alligator, calf leather, shell cordovan and NATO fabric, with bespoke personalisation available through the Casati Milano atelier.

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

A quality leather strap — alligator or vegetable-tanned calf — typically lasts between two and four years with daily wear, provided it is kept away from prolonged moisture and perspiration. Storing the watch on a cushion and occasionally applying a neutral leather conditioner will significantly extend the strap's life. Shell cordovan, owing to its natural density, tends to develop a patina rather than deteriorate, and generally outlasts conventional leathers.
