Frequently asked questions
What is the lug width of the Bremont ALT1 ALT1WTBK?
The lug width of the Bremont ALT1 ALT1WTBK is 22 mm. This measurement represents the distance between the inner attachment points on the case. Bremont has standardised this dimension to ensure compatibility with quality aftermarket straps. It is critical to respect this measurement when purchasing: undersized straps will cause lateral micro-movement, whilst oversized straps will not insert at all.
Which strap type is best suited to the Bremont ALT1 ALT1WTBK?
For the ALT1WTBK we recommend three options according to intended use. Vegetable-tanned alligator with satin texture offers tactile elegance and structural durability: alligator leather resists abrasion naturally thanks to its scale structure. A 22 mm standard NATO strap in regenerated polyester fibres guarantees maximum operational practicality: synthetic fabric does not absorb moisture and dries within minutes. Vulcanised rubber (FKM) represents the solution for high-stress environments, with thermal resistance up to 100°C and secure grip even with perspiring hands.
How do you change the strap on a Bremont ALT1 ALT1WTBK?
Strap changing requires a specific tool (spring bar tool or 22 mm dedicated pin remover). Procedure: position the watch on a stable surface, insert the pin remover into the lateral opening of the lug (small cylindrical hole), apply downward pressure until the pin fully extracts. The pin is not soldered, so it will come out completely. Insert the new strap aligning the holes, reintroduce the pin from the opposite side until it clicks into place. The procedure takes 2-3 minutes for someone with the correct tool: we advise against improvisation with screwdrivers, which damage the lugs.
Is an aftermarket strap from a different brand compatible with the ALT1WTBK?
Yes, provided the lug width is exactly 22 mm. Any strap (leather, NATO, rubber or hybrid fabrics) with this dimension will fit perfectly. Always verify the technical specifications from the seller before purchase: some brands declare 22 mm but have manufacturing tolerances of ±0.5 mm. We recommend straps from suppliers specialising in tool watches, where tolerances are guaranteed within ±0.2 mm.
How long does a leather strap last on a Bremont ALT1 ALT1WTBK?
A high-quality vegetable-tanned alligator strap lasts on average 4-6 years with daily use and proper maintenance. Vegetable-tanned calf leather has similar longevity (4-5 years). Durability depends on: frequency of use (daily vs occasional), exposure to moisture and UV rays, preventive maintenance (apply conditioner every 8-12 months, dry after rain, avoid prolonged contact with perspiration). Vegetable-tanned straps develop visible patina after 6-12 months, a sign of natural ageing rather than deterioration. Once worn out, the strap is easily replaceable in 5 minutes with a pin remover.
