Strap for ALT1-ZT-51

The Bremont ALT1-ZT/51 is fitted with a <a href="/pages/termine-glossario/misura-ansa">22mm lug width</a>. This measurement represents the distance between the extremities of the pins that secure the strap to the case, determining compatibility with any strap of the same width. To verify your lug width accurately, measure the distance between the two pins using a digital calliper or a millimetre ruler, ensuring the instrument is positioned perpendicular to the case.

We recommend a high-quality <a href="/pages/termine-glossario/concia-vegetale">vegetable-tanned leather</a> strap for the ALT1-ZT/51, such as Tuscan leather, which emphasises the watch's instrumental character. An antique brown strap develops a natural patina over time, complementing the satin-brushed stainless steel case. Alternatively, a neutral-toned NATO strap or an FKM rubber strap provide versatility and practical daily use, particularly suited for professional or recreational environments.

Changing the strap is a straightforward operation requiring no specialised tools. Position the watch with the caseback facing upwards, locate the pins securing the strap to the case lugs, and using a spring bar tool or thin blade, apply gentle pressure to retract the internal spring of the pin. Once the pin is extracted, the original strap releases easily. Insert the new strap, aligning it perfectly with the case lugs, and push the pin until the spring clicks into position. Verify that the strap is securely fastened by gently pulling in all directions.

Any strap with a <a href="/pages/termine-glossario/misura-ansa">22mm lug width</a> is compatible with the ALT1-ZT/51. You may choose from alligator, calf, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a>, vegetable-tanned Tuscan leather, technical nylon NATO straps, or FKM rubber straps. Milano Straps offers a comprehensive collection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-22mm">22mm straps</a> customisable in numerous colours and finishes.

The longevity of a leather strap depends on the tanning method and intensity of use. A high-quality <a href="/pages/termine-glossario/concia-vegetale">vegetable-tanned</a> strap, such as Tuscan leather, guarantees a lifespan of 3–5 years with moderate daily use, whilst developing a characteristic patina that increases its aesthetic appeal. An alligator or shell cordovan strap may last 5–7 years. To extend longevity, avoid prolonged moisture exposure, occasionally apply a leather-specific conditioner, and allow the strap to breathe by rotating it with alternative variants.
