Strap for ALT1-WT Worldtimer White

The lug width of the Bremont ALT1 ALT1WTWH is 22 millimetres. This measurement represents the interior distance between the two lugs of the case where the strap is secured via spring bar. To verify it correctly, use a calliper to measure the internal spacing between the two lugs – the value must be exactly 22mm. Any strap compatible with a 22mm lug width will fit your ALT1WTWH perfectly.

The choice depends on usage context and personal preference. For formal or office settings, an alligator or shell cordovan strap amplifies the elegance of the Bremont chronograph. For daily wear with natural patina development, vegetable-tanned leather is ideal. For humid environments, airport settings, or dynamic activities, premium nylon NATO or FKM rubber straps ensure practicality and security. The stainless steel case of the ALT1WTWH pairs well with any material, making the choice primarily one of personal style.

Changing the strap on the ALT1WTWH is a straightforward operation that requires no specialist skills. Obtain a spring bar tool (a small lever often supplied with quality artisanal straps). Insert the tip of the tool into the small slot positioned beneath the upper lug tube, apply gentle upward pressure to release the spring bar (the metal pin securing the strap). Completely remove the spring bar from the old strap and repeat for the other lug. Finally, position the new strap by aligning its holes with the case pins, then gently click the spring bar into place. Always work on a soft surface to prevent damage to the case.

Yes, the Bremont ALT1 ALT1WTWH is compatible with any strap featuring a 22mm lug width. There are no technical restrictions regarding brand or strap type: any artisanal leather strap with 22mm lug width fits perfectly. What matters is that the spring bar (the internal metal tube) has the same diameter as the original Bremont tube, typically 1.5mm. However, to ensure build quality and longevity, we recommend selecting straps produced by specialised craftspeople rather than generic budget solutions.

Durability depends on material and usage frequency. A vegetable-tanned leather strap, if worn daily, maintains structural integrity for 4–6 years, though the leather visibly deteriorates after 2–3 years of intensive use. Alligator and shell cordovan are more resistant and can last 6–10 years. A NATO or rubber strap, with minimal maintenance, easily exceeds 10 years. Strap replacement frequency is more an aesthetic choice than a functional necessity: many collectors rotate straps to keep their watch visually fresh. Prolonged exposure to sunlight, moisture, and heat accelerates leather ageing; NATO and synthetic materials are unaffected by these factors.
