Strap for Navitimer B19 Chronograph 43 Perpetual Calendar Stainless Steel - Platinum / Ice Blue / Bracelet

The Breitling Navitimer PB1920251C1A1 features a lug width of 22 mm. For a proper fit, straps with curved ends are required to follow the contour of the case lugs, preventing mechanical stress on the lug tips.

For the platinum and stainless steel version, a vegetable-tanned alligator strap with a bombé grain offers the strongest aesthetic coherence. Box-calf leather recalls the instrument's original 1950s aesthetic. A plain-coloured nylon NATO strap in neutral tones suits sporting use. The lug width is 22 mm with curved ends.

Use a fine-tipped or fork-style spring bar tool to remove the spring bars securing the strap to the 22 mm lugs. Work on a soft surface to protect the platinum case from scratches. Original Breitling spring bars have a specific diameter: verify compatibility before fitting an aftermarket strap.

Yes. Compatible aftermarket straps must have a 22 mm lug width and, ideally, curved ends to match the Navitimer case profile. Milano Straps offers a selection of handcrafted leather, NATO, and rubber straps specifically suited to this size, available with a deployant clasp or traditional buckle.

Longevity depends on material and usage. A quality alligator strap, properly maintained and kept away from prolonged water or perspiration exposure, will last between three and five years. Calf leather averages two to three years. Vegetable-tanned leather develops a patina over time that enhances its appearance, and regular conditioning with a neutral product significantly extends its service life.
