Strap for Navitimer 01 Stainless Steel / Stratus Gray / Calf / Folding

The lug width of the Breitling Navitimer AB012124/F569/436X/A20D.1 is 22 mm. This measurement refers to the internal distance between the two case lugs at the strap attachment point. Precise adherence to this dimension, with minimal tolerance, is essential to ensure a secure fit and eliminate lateral play.

For the Navitimer AB012124/F569/436X/A20D.1 with its black dial and stainless steel case, a vegetable-tanned calf leather strap with a matte finish is the most coherent choice, complementing the instrument-oriented character of the watch. Alternatively, a symmetric-belly alligator strap in matte finish suits formal contexts, whilst a textured rubber strap is better suited for active use. A stainless steel deployant clasp is recommended for any leather variant to reduce mechanical stress on the strap attachment.

To replace the strap on the Navitimer AB012124/F569/436X/A20D.1, you will need a fine-tipped spring bar tool or a precision flat-head screwdriver of 1.0–1.2 mm. Insert the tool into the spring bar slot on the lug, compress the spring mechanism and slide the strap free. Take care not to scratch the case: it is advisable to protect the lug surface with low-tack adhesive tape. Fitting the new strap follows the reverse procedure.

Yes. The Navitimer AB012124/F569/436X/A20D.1 uses standard 22 mm spring bars, making it compatible with any aftermarket strap produced in that width with a straight or slightly shaped end profile to accommodate the lug curve. Milano Straps offers an extensive selection of handcrafted 22 mm straps in leather, rubber and nylon, with customisable stitching and finishes, all fitting the original case without any modification.

The lifespan of a leather strap depends on material quality, frequency of use and exposure to perspiration and environmental conditions. A high-quality vegetable-tanned calf strap, rotated with other straps and stored correctly, can last between three and five years whilst retaining its shape and structural integrity. Alligator straps, owing to the denser structure of the hide, tend to be more resistant to abrasion. Milano Straps provides an 18-month guarantee against manufacturing defects on all its straps.
