Frequently asked questions

What is the lug width of the Breitling Avenger V1731010/BD12/105W/M20BASA.1?

The lug width of the Breitling Avenger V1731010/BD12/105W/M20BASA.1 is 24 mm. This specific dimension corresponds to the 48 mm case diameter and requires straps precisely dimensioned for this lug width. Standard 20 or 22 mm straps cannot be used without compromising proper fitment at the case lugs. Milano Straps offers a complete collection of 24 mm compatible straps for this model.

Which strap is most suitable for the Breitling Avenger V1731010/BD12/105W/M20BASA.1?

For this oversized titanium case, we recommend handcrafted alligator straps (black or dark brown) for formal and civilian contexts, or natural shell cordovan for those seeking sophisticated aged patina. For tactical-military environments or extreme exposure conditions (salt water, mud), we propose vegetable-tanned straps that ensure biological resistance and lasting elasticity. A military NATO or vulcanised rubber strap represents a pragmatic alternative for authentic operational use. The choice depends on context of use and personal aesthetic preference.

How do you change the strap on the Breitling Avenger V1731010/BD12/105W/M20BASA.1?

The Breitling Avenger V1731010/BD12/105W/M20BASA.1 uses a <a href="/pages/termine-glossario/deployante">deployante</a> (folding clasp) for secure opening and closing. To change the strap, the deployante must be removed from the old leather using a dedicated tool (spring bar tool) or by a specialist watchmaker. Subsequently, the deployante is installed on the new 24 mm strap. Milano Straps provides detailed instructions and mounting support; the Casati Milano atelier also offers professional installation service by appointment.

What is the aftermarket strap compatibility for the Breitling Avenger V1731010/BD12/105W/M20BASA.1?

The Breitling Avenger V1731010/BD12/105W/M20BASA.1 is compatible exclusively with 24 mm artisanal straps, provided the front section (thickness) is between 3.5 and 4.5 mm to ensure correct fitment. Milano Straps produces 24 mm straps specifically dimensioned for this case, crafted in Italian leather with manual workmanship. It is essential to avoid cheap imported straps, which cause play and scratches to the titanium case lugs.

How long does a leather strap last on the Breitling Avenger V1731010/BD12/105W/M20BASA.1?

The lifespan of an artisanal strap depends on leather type and usage intensity. An alligator or shell cordovan strap subjected to medium use (4-5 days per week, dry environments) maintains structural integrity for 3-5 years before requiring surface regeneration. Vegetable-tanned leather ensures greater biological longevity even in humid environments. Milano Straps provides 18-month warranty on all straps, while the Casati Milano atelier offers periodic regeneration and maintenance services to extend strap lifespan indefinitely. The natural patina that develops is a sign of noble ageing, not degradation.
