Strap for Breitling for Bentley GMT Gold / Black

The Breitling for Bentley R4736212B934 has a lug width of 20mm. This measurement should be taken internally between the two lugs using a digital calliper positioned as close as possible to the case, to avoid inaccurate readings caused by lug curvature.

For the 49mm red gold case, the most harmonious materials are belly alligator in chocolate or cognac tones and shell cordovan in whisky colour, both well-suited to complement the warm chromatics of red gold. Those preferring a sportier register may opt for a vegetable-tanned calf leather or a textured rubber strap.

Strap replacement is carried out using standard 20mm spring bars fitted into the case lugs. A bifurcated spring bar tool is used to compress the bar and release the strap. It is advisable to work on a soft surface to avoid scratching the red gold case.

Yes. Any 20mm strap with an 18mm taper and standard length (approximately 115/75mm) is technically compatible. Milano Straps offers a selection of handcrafted leather, cordovan and rubber straps specifically adaptable to this reference, available online or in bespoke configuration at the Casati Milano atelier.

Longevity depends on the material and frequency of wear. A quality alligator strap, properly maintained (dried after water exposure, conditioned every 3-4 months), retains structural and aesthetic integrity for 3-5 years. Shell cordovan, owing to its dense fibre structure, tends to last longer whilst developing a distinctive patina. Quality rubber straps typically last 2-4 years with regular use.
