The Navitimer AB0138241C1A1, seen from the bench

The Breitling Navitimer AB0138241C1A1 is a 43 mm stainless steel chronograph descended from the 1952 original, an AOPA-certified navigation instrument for pilots. It houses the caliber B01, Breitling's in-house automatic movement with 28,800 vibrations per hour and approximately 70 hours power reserve, featuring hours, minutes, small seconds, date, and column-wheel chronograph. COSC-certified chronometer precision is documented at -4/+6 seconds per day. The 22 mm lug width is proportioned to the case and maintains the Navitimer's characteristic architecture with its rotating bezel and screw-down crown.

How do you change the strap on a Breitling Navitimer AB0138241C1A1?

The strap on the Navitimer AB0138241C1A1 is removed using a flat-tip spring bar tool. The 22 mm spring bars are compressed laterally to release the strap from the lugs.

How long does a leather strap last on a Breitling Navitimer AB0138241C1A1?

A quality leather strap on the Navitimer AB0138241C1A1 typically lasts between 2 and 4 years with daily wear, depending on perspiration, humidity exposure, and maintenance.
