Strap for Premier Automatic 40 Stainless Steel / Blue / Tokyo Boutique

The lug width of the Breitling Premier A453401A1C1P1 is 20mm. This measurement should be taken internally between the two lugs using a digital calliper, excluding the outer walls of the case. The Premier's lugs feature a slightly curved profile, so compatibility with pre-curved strap ends is recommended for a clean, flush fit.

For the Premier A453401A1C1P1, with its porcelain white enamel dial and brushed stainless steel case, a vegetable-tanned alligator strap is the most coherent choice given the watch's formal character. Smooth tanned calfskin offers versatility for everyday wear, while shell cordovan provides a long-lasting, dense patina. For sport or summer use, a 20mm vulcanised rubber strap maintains visual proportions whilst ensuring water resistance.

To change the strap on the Breitling Premier A453401A1C1P1, a spring bar tool is required. The spring bars are located internally within the lugs and must be compressed laterally to release the strap. It is advisable to work on a soft surface to protect the dial and case from scratches. If in any doubt, a watchmaker or the Casati Milano atelier is best placed to carry out the operation.

The lifespan of a leather strap on the Breitling Premier A453401A1C1P1 depends on the material and frequency of use. A quality alligator strap, properly maintained and rotated with other straps, can last between 3 and 5 years whilst retaining its structural integrity and appearance. Tanned calfskin offers a similar lifespan but is more susceptible to moisture. Shell cordovan, owing to the density of its fibres, ranks among the most durable options. Casati Milano straps carry an 18-month warranty against manufacturing defects.
