Strap for Chrono-Matic 49 Black / Rubber

The lug width of the Breitling Chrono-Matic A1436002.B920 is 24 millimetres. This measurement is specific to this model and represents the distance between the case lugs. A compatible strap must have exactly 24 millimetres width at the end that inserts into the springbar pins.

For the Chrono-Matic A1436002.B920, straps in alligator (black, dark brown or grey), vegetable-tanned calf (tobacco, cognac), shell cordovan or military textiles are ideal. Alligator communicates sporty elegance, calf develops natural patina over time, whilst NATO references aviation chronograph heritage. The choice depends on intended use: formal with polished alligator, daily wear with calf leather, technical with NATO or rubber.

To change the strap, you require a springbar removal tool to gently compress the elastic pins positioned at the case ends. Insert the tool into the pin groove, compress to release the pin, extract the old strap and insert the new one, ensuring the pins snap securely into position. Verify both sides are firmly attached before wearing the watch.

Yes, any strap with a 24-millimetre lug width is compatible with the Breitling A1436002.B920. Always verify that the strap ends (sections inserting into the pins) respect exactly 24 millimetres width. Milano Straps offers hand-crafted straps in various leathers and textiles, specifically sized for this width and guaranteed compatible.

A quality leather strap, such as those crafted in alligator or calf, typically lasts 5-7 years with regular daily use. Longevity depends on environmental humidity, frequency of use and periodic maintenance (gentle cleaning and conditioning). Milano Straps straps carry an 18-month warranty and support bespoke restoration interventions via the Casati Milano atelier to extend accessory lifespan.
