Strap for Minute Repeater Tri-Axial Tourbillon Titanium

The lug width (also called ansa width) of the Girard-Perregaux Bridges 99830-21-000-BA6A is precisely 22mm. This measurement refers to the distance between the two lugs on the case where the strap attaches. It is essential to verify this dimension before purchasing an aftermarket strap to ensure perfect compatibility and maintain the correct aesthetic proportions of this oversize timepiece.

For a watch of this technical and formal calibre, we primarily recommend alligator dyed in black or dark brown, which emphasizes visual contrast with the titanium case and highlights the bridge geometry. Alternatively, burgundy shell cordovan creates a refined dialogue with the gold-plated components. For a more contemporary-sport approach, a NATO in anthracite grey or premium rubber ensures practicality without compromising the watch's identity and architectural narrative.

Changing the strap requires a spring bar tool to compress the springs that secure the lugs to the case. Position the tool in the lateral slots of the lugs, gently compress the spring, then extract the previous strap. Insert the new strap into the upper slot, release the spring and verify it is firmly locked. For luxury watches like the Bridges, we recommend having this operation performed by an official service centre to prevent case damage.

All straps with a 22mm lug width are compatible with the Bridges 99830-21-000-BA6A. Milano Straps offers a specialised collection of bespoke artisanal straps in alligator, calf, shell cordovan, NATO and rubber, available in various finishes and colours. We recommend selecting straps with quality passants and superior finishing to honour the mechanical complexity of the timepiece.

The lifespan of a quality leather strap depends on intensity of use and climatic conditions. A well-maintained alligator or shell cordovan can last 5–8 years with regular wear, developing a desirable patina over time. Prolonged exposure to humidity, heat and perspiration reduces longevity. A NATO strap in technical fabric has a similar lifespan if made from quality materials. Premium rubber can last 3–5 years before requiring replacement. Milano Straps recommends periodic maintenance and rotation between multiple straps to extend the life of each element.
