FAQ
What is the lug width of the Bremont ALT1-B?
The Bremont ALT1-B features a lug width of 22 mm, which is the standard specification for aviation-grade chronographs in this category. This 22 mm dimension ensures compatibility with an extensive range of professional straps, including structured leather, alligator, and ballistic nylon NATO options.
Which strap is recommended for the ALT1-B?
For the ALT1-B, we recommend alligator leather for formal luxury applications, Tuscan vegetable-tanned leather for authentic aviation heritage, ballistic nylon NATO for tactical aesthetics, or technical rubber for daily-wear practicality. Your choice depends on intended use: aviator brown emphasises the dark dial, black alligator transforms the watch into formal instrumentation, military grey evokes British aviation history.
How do I change the strap on the Bremont ALT1-B?
Strap changing requires a dedicated spring bar tool. Position the tool beneath each spring bar (the lateral anchoring lugs), apply gentle inward pressure to disengage the bar from the case lugholes, then extract the worn strap. Align the new strap's holes with the spring bars, then reposition each bar until you hear an audible click. The procedure takes approximately 2-3 minutes.
Are aftermarket straps compatible with the ALT1-B?
Yes, all aftermarket straps with a 22 mm lug width are fully compatible with the ALT1-B. The Bremont case utilises standard spring bars, permitting the use of straps from specialised artisanal suppliers. We recommend verifying that your chosen strap does not exceed 4 mm thickness when folded, ensuring proper deployant clasp closure.
How long does a leather strap last on the ALT1-B?
A high-quality leather strap, featuring vegetable tanning, maintains structural functionality for 3-5 years of daily wear. Longevity depends on environmental factors (solar exposure, humidity), usage frequency, and periodic maintenance. Applying leather conditioner every 6-8 months significantly extends material life. Alligator straps, due to superior fibre density, achieve 7-10 years of intensive use.
