Strap for Montbrillant Olympus Black

The lug width of the Breitling Montbrillant A1935012.B774 is 20 mm. This measurement should be verified using a digital calliper, measuring the internal distance between the two lugs on the case back side. Any strap with a 20 mm attachment is directly compatible with this reference.

For the Montbrillant A1935012.B774, the most suitable options consistent with its aeronautical and instrumental character are vegetable-tanned calf leather with smooth grain, shell cordovan, and nylon NATO straps. Those seeking a more formal pairing may consider an alligator strap with a stainless steel deployant clasp, which complements the satin-finished surfaces of the 42.10 mm case.

Replacing the strap on the Montbrillant A1935012.B774 requires a fine-tipped springbar tool to remove the spring bars housed within the lugs. It is advisable to work on a soft surface to protect the bezel and the satin-finished case surfaces. The correct attachment size for any replacement strap is 20 mm.

Yes. Any strap with a 20 mm attachment width is compatible with the Montbrillant A1935012.B774, provided the spring bars are standard diameter (1.5 mm). Milano Straps offers a curated selection of handcrafted leather, rubber, and nylon straps specifically suited for Breitling chronographs of this family, available in the 20mm strap section.

The lifespan of a leather strap depends on the quality of the tanning process and daily use. A well-crafted vegetable-tanned calf leather strap, with minimal care — avoiding prolonged water exposure and occasionally applying a neutral conditioner — will retain its structural and aesthetic integrity for 18 to 36 months of regular wear. Shell cordovan, owing to its dense fibrous structure, tends to last considerably longer.
