Strap for ALT1-C Polished Black

The lug width of the Bremont ALT1-C/PB is 22mm. This measurement refers to the internal distance between the two lug flanges on the case that accommodate the watch pin. To measure correctly, use a digital calliper positioned from the centre of one lug to the centre of the opposite lug: the value must be 22mm. All straps compatible with this specification will fit the watch perfectly without requiring modification.

The ideal strap depends on your intended use. For formal occasions, an alligator strap with vegetable tanning in midnight blue or aged brown transforms the watch into an elegant instrument; for daily and sporting use, a NATO in anthracite grey or dark blue emphasises the avionic heritage; for maximum versatility, a vegetable-tanned calf offers the finest balance between refinement and practicality. Vulcanised rubber remains the technically superior choice for humid or saline environments, ensuring durability and comfort in challenging conditions.

The Bremont ALT1-C/PB uses standard 22mm push-pin lugs. To change the strap, proceed as follows: position the watch with the lug facing towards you, locate the small access hole on the side of the case, insert a spring bar tool into the hole and gently push to release the internal spring mechanism. The pin will disengage from its seat. Repeat this operation on the opposite lug, then remove the old strap. Install the new strap by aligning the holes with the pins and press firmly until the spring engages. Verify that the strap is securely fastened on both sides before wearing.

Yes, any strap with a 22mm lug width is compatible with the ALT1-C/PB. High-quality aftermarket straps, such as handcrafted alligator, shell cordovan or European-manufactured NATO options, fit the model perfectly without requiring modifications. Ensure only that the lug width is exactly 22mm and that the pins are standard push-pin type. Many collectors choose aftermarket straps to personalise their watch's appearance and vary the style according to seasons or occasions.

The lifespan of a leather strap depends on usage intensity, material quality and storage conditions. An alligator or vegetable-tanned calf strap, worn regularly, has an average life of 3–5 years before requiring professional replacement or repair. If worn occasionally and stored in a dry environment, the lifespan extends to 7–10 years. NATO straps, due to their textile nature, offer superior durability (5–8 years of intensive use), whilst vulcanised rubber can last up to 10 years if kept clean and protected from prolonged UV exposure. Regular maintenance, including cleaning and conditioning with appropriate creams, significantly extends strap lifespan and aesthetic development.
