It features the automatic B01 caliber with a column-wheel chronograph function and chronometer certification. The RB0138211B1P1 reference has 22mm lugs and a display with hour, minute, small second, and date.

Frequently asked questions

What is the lug width of the Breitling Navitimer RB0138211B1P1?

The Breitling Navitimer RB0138211B1P1 features a 22mm lug width, standard for its 43mm case. For an accurate measurement, use a digital calliper placed between the lugs on the inner side, flush against the case.

What is the best strap for the Breitling Navitimer RB0138211B1P1?

The Red Gold 43mm case pairs particularly well with vegetable-tanned Tuscan calf leather in cognac or tobacco, or with a glossy alligator strap in bordeaux for formal occasions. For daily or sporting use, a nylon NATO or black technical rubber strap preserves the Navitimer's tool watch character.

How do you change the strap on the Breitling Navitimer RB0138211B1P1?

The strap is removed using a fine-tipped spring bar tool inserted into the lug channel, pressing the spring bar inward to release it. Care must be taken not to scratch the Red Gold case: use a soft cloth to protect the surface and, where possible, entrust the operation to a watchmaker or authorised retailer.

Are there aftermarket straps compatible with the Breitling Navitimer RB0138211B1P1?

Yes. Any strap with a 22mm lug width is technically compatible with the Navitimer RB0138211B1P1. MilanoStraps offers a curated selection of handcrafted straps in leather, alligator, NATO and rubber, proportioned for 43mm cases with stitching and finishes appropriate to this calibre of timepiece.

How long does a leather strap last on a Breitling Navitimer RB0138211B1P1?

Longevity depends on leather quality, frequency of wear and maintenance. A high-grade vegetable-tanned calf strap, properly conditioned with natural wax and kept away from prolonged moisture exposure, can last between three and five years while developing a rich, characterful patina. Casati Milano straps carry an 18-month production warranty.
