Strap for BR 126 Insigna ES Chronograph

The lug width of the BRV126-BL-CA-CO/ES is 20 mm. This measurement represents the distance between the centres of the two attachment pins. To verify accuracy, place a ruler on the outer side of the lugs: the result must be precisely 20 mm. This technical specification determines the compatibility of all aftermarket straps for this model.

The choice depends on intended usage. For a purely vintage approach, alligator with vegetable tanning offers natural texture and evolving patina over time. Calf leather with a sanded finish provides a compromise between elegance and practicality, ageing gracefully. For intensive use or extreme conditions, natural rubber or NATO canvas straps allow you to preserve the watch without compromising functionality.

The BRV126-BL-CA-CO/ES features integrated lugs, which simplifies the process. Obtain a spring bar tool or a fine screwdriver. Place the watch on a soft cloth to prevent scratches. Insert the tool into the lateral slot of the attachment pin (from inside the lug) and apply gentle outward pressure until the pin releases. Repeat for the other pin. Align the holes of the new strap with the lugs and reinsert the pins until fully closed.

All straps specifically constructed for 20 mm lug width are compatible. It is essential to verify this measurement at the time of purchase to avoid misalignment or premature wear. Online you will find collections dedicated to this size, available in alligator, calf, NATO and rubber. The Casati Milano atelier also offers bespoke straps crafted to order, with personal leather selection and custom finishes upon request.

A quality leather strap, with vegetable tanning or shell cordovan, has a lifespan of 3–5 years with regular use and appropriate maintenance. Longevity depends on UV exposure, humidity and frequency of use. Straps in non-vegetable tanned natural leather may degrade more rapidly. To extend the strap's life, avoid prolonged water exposure, apply natural conditioners every 6–12 months and store in dry environments. Rubber or NATO straps require minimal maintenance and have a longer lifespan.
