What is the lug width of the Breitling for Bentley A4436212B728?

What is the best strap for the Breitling for Bentley A4436212B728?

For a 48.70mm case such as that of the Breitling for Bentley A4436212B728, the most suitable materials are alligator leather — valued for its structured grain and the patina it develops over time — and shell cordovan for a compact, formal surface.
