Strap for BR 126 Officer Black Chronograph

The lug width of the Bell & Ross Vintage BRG126BLSTSCR is 20 millimetres. This measurement represents the internal distance between the two lugs of the case where the strap attaches. To verify it correctly, remove the original strap and measure the perpendicular distance between the attachment points using a millimetre ruler or digital calliper.

The ideal strap depends on your intended use. For an elegant and formal finish, we recommend alligator with vegetable tanning or shell cordovan, which enhance the aviator chronograph character. For daily wear, a superior quality calf leather offers the best balance between aesthetics and practicality. For sports or humid environments, technical rubber or fabric straps ensure durability and ease of maintenance. All our 20mm straps are available online and customisable.

To change the strap, use a spring bar removal tool available online or from specialist jewellers. Position the small hook of the tool in the hole of the lug spring, then gently press downward to release the lug. Repeat on the other lug. When inserting the new strap, align the strap loops with the case holes and push until you hear a click. If you prefer a guided experience, our Casati Milano atelier offers a replacement service by appointment with personal consultation.

Yes, any strap with a 20 millimetre lug width is compatible with the BRG126BLSTSCR. Compatibility is guaranteed by the standardised lug width and the spring bars included in the strap. We recommend, however, that you verify the total length of the strap (sum of the two segments) so that it fits your wrist correctly. Our 20mm straps are available in various lengths and customisable on request.

The lifespan of a leather strap varies depending on the material and intensity of use. A quality calf leather strap, with moderate daily wear, typically lasts 3-5 years before showing signs of significant wear. Alligator and shell cordovan, thanks to their more resistant fibrous structure, can last 5-7 years or more. Natural leather with vegetable tanning tends to age elegantly, developing characteristic patina. To prolong the life of your strap, avoid prolonged exposure to salt water and excessive humidity, and occasionally apply a specific leather balm. All Casati Milano straps include an 18-month warranty against manufacturing defects.
