Frequently asked questions

What is the lug width of the Breitling Chrono-Matic A1436002.G658?

The lug width of the Breitling Chrono-Matic A1436002.G658 is 24mm. This measurement is taken with a digital calliper or a millimetre ruler positioned between the inner faces of the lugs, at the narrowest point adjacent to the case. It is a large lug width, consistent with the 49mm case diameter.

What is the best strap for the Breitling Chrono-Matic A1436002.G658?

For the Breitling Chrono-Matic A1436002.G658, the most appropriate choices are: vegetable-tanned alligator for formal contexts, saddle-stitched calf leather for structured daily wear, vulcanised rubber for sporting use, and ballistic nylon NATO for lightweight versatility. In all cases, the 24mm lug width demands a strap with sufficient thickness and rigidity to match the case's mass.

How do you change the strap on the Breitling Chrono-Matic A1436002.G658?

Strap replacement on the Breitling Chrono-Matic A1436002.G658 is carried out using a dedicated spring bar tool or a lever-type screwdriver. Insert the tool into the lug slot, compress the spring bar and slide it out laterally. The process is fully reversible and requires no professional tools, though working on a soft surface is advisable to protect the case from scratches.

Are there aftermarket straps compatible with the Breitling Chrono-Matic A1436002.G658?

Yes. Any strap with a 24mm lug width is dimensionally compatible with the Breitling Chrono-Matic A1436002.G658. milanostraps.it offers a selection of handcrafted straps in various leathers and materials, specifically produced for large-format timepieces. For a bespoke solution, Casati Milano atelier crafts made-to-measure straps with direct material selection.

How long does a leather strap last on a Breitling Chrono-Matic A1436002.G658?

Longevity depends on material and usage. A quality calf leather strap, with daily wear, has an average lifespan of 12 to 24 months. A vegetable-tanned alligator strap, owing to the higher fibre density, can last between 3 and 5 years with proper care. Shell cordovan, given its compact structure, ranks among the most durable options. Prolonged exposure to perspiration and moisture accelerates deterioration. The Casati Milano guarantee covers manufacturing defects for 18 months.
