FAQ
What is the lug width of the Breitling Premier JB2120A61B1P1?
The lug width of the Breitling Premier B21 Chronograph 42 Boutique Edition (ref. JB2120A61B1P1) is 20 mm. This measurement is taken between the two lugs at the point where the strap attaches to the case, using a millimetre calliper.
What is the best strap for the Breitling Premier B21 Chronograph 42 in white gold?
For an 18-carat white gold case, the most coherent choice is a belly-cut alligator strap in dark tobacco, midnight blue or anthracite grey. Alternatively, a vegetable-tanned calf leather or shell cordovan strap develops a distinguished patina over time. For less formal occasions, a textured rubber strap is a practical and aesthetically consistent option.
How do I change the strap on the Breitling Premier JB2120A61B1P1?
The strap is replaced using a springbar tool to remove the 20 mm springbars housed within the lugs. It is advisable to rest the case on a soft cushion to avoid scratching the white gold surfaces. The operation can be carried out independently or entrusted to a watchmaker or the Casati Milano atelier.
Are there aftermarket straps compatible with the Breitling Premier 42mm with a 20mm lug width?
Yes. Any strap with a straight or slightly curved 20 mm attachment is technically compatible. Milanostraps.it offers a selection of handcrafted 20 mm straps in various materials, designed to fit the Premier's lugs without any modification to the case.
How long does a leather strap last on a Breitling Premier in white gold?
Longevity depends on the material and frequency of use. A quality alligator strap, used in rotation, maintains its structural and aesthetic integrity for 3 to 5 years. Vegetable-tanned calf leather develops an appealing patina within the first year but is more susceptible to moisture. Casati Milano straps carry an 18-month warranty against manufacturing defects.
