Frequently asked questions

What is the lug width of the Bremont ALT1-C/RG?

The Bremont ALT1-C/RG features a lug width of 22 millimetres. This dimension represents the distance between the case lugs where the strap attaches and determines compatibility with aftermarket straps. Accurate measurement of the lug width is essential before purchasing a replacement strap.

Which strap do you recommend for the Bremont ALT1-C/RG?

For the ALT1-C/RG, we recommend a traditionally tanned vegetable leather strap, such as Tuscan Heritage leather in tobacco brown. This material enhances the avionic nature of the watch, developing a noble patina over time. Alternatively, shell cordovan offers superior resistance for intensive use, whilst alligator leather imparts formal elegance.

How do you change the strap on a Bremont ALT1-C/RG?

Strap replacement requires extraction of the spring bars that connect the case to the lugs. Use a dedicated spring bar tool to compress the pin and gently extract it from the case. Position the new strap, insert the spring bar into the opposite hole and release. Verify that the spring bar is properly seated. We recommend professional installation if you do not possess the specific tool.

Are aftermarket straps compatible with the Bremont ALT1-C/RG?

Yes, the Bremont ALT1-C/RG is fully compatible with aftermarket straps featuring a 22mm lug width. Milano Straps offers a comprehensive collection of artisanal straps crafted from vegetable leather, shell cordovan, alligator leather and technical materials, specifically dimensioned for this size.

How long does a leather strap last on the Bremont ALT1-C/RG?

The lifespan of a leather strap varies based on material type and intensity of use. Traditionally tanned vegetable leather typically lasts 2-4 years under daily wear conditions. Shell cordovan can last 5-7 years owing to superior density. Regular maintenance—cleaning and conditioning—significantly extends strap longevity.
