FAQ
What is the lug width of the Breitling Colt A7738711.BB51.133S?
The Breitling Colt A7738711.BB51.133S features a 33mm case with a lug width of 16mm. This is the correct measurement to use when sourcing any aftermarket or bespoke replacement strap for this reference.
What is the best strap for the Breitling Colt A7738711.BB51.133S?
For the 33mm Colt, we recommend a vegetable-tanned calf leather strap with a smooth or grained finish for everyday wear, or a Bombé-cut alligator belly strap for formal occasions. A moulded rubber strap suits sporting use. A stainless steel deployant clasp offers the best visual symmetry with the case.
How do you change the strap on a Breitling Colt A7738711.BB51.133S?
To replace the strap on the Breitling Colt A7738711.BB51.133S, use a fine-tipped spring bar tool. Insert the tool into the spring bar slot inside the lug, compress the bar and slide the strap outward. Take care not to scratch the polished surfaces of the lugs. If in doubt, entrust the operation to a watchmaker.
Are there aftermarket straps compatible with the Breitling Colt A7738711.BB51.133S?
Yes. Any strap with a 16mm attachment and standard length (typically 105/65mm or 110/70mm) is compatible with the Breitling Colt A7738711.BB51.133S. Milanostraps.it offers a curated selection of handcrafted 16mm straps specifically suited to this case size.
How long does a leather strap last on a Breitling Colt?
A quality handcrafted leather strap on a 33mm Colt typically lasts between 18 and 36 months with daily wear, depending on the material and conditions of use. Vegetable-tanned calf develops a personal patina over time but should be kept away from prolonged exposure to water and perspiration. Alligator leather is more abrasion-resistant but requires the same level of care. Casati Milano straps carry an 18-month warranty against manufacturing defects.
