The ALT1 ALT1CGNbr, seen from the bench

The Bremont ALT1CGNbr is a 43 mm stainless steel chronograph rooted in British aviation engineering principles. It features the internal Bremont caliber BE-50AE manual-wind certified chronometer movement with hour, minute, small seconds, date and chronograph functions, delivering a 60-hour power reserve. The 22 mm lug width accommodates the bidirectional rotating bezel and anti-reflective sapphire crystal, with 100 metres water resistance for daily wear.

Frequently asked questions

What is the lug width of the Bremont ALT1CGNbr?

The lug width of the Bremont ALT1CGNbr is 22 millimetres. This dimension is measured internally between the watch lugs and permits the use of all straps with ends specifically designed for this width, ensuring perfect fit on the case.

Which strap do you recommend for the Bremont ALT1CGNbr?

The ideal strap depends on context of use. For formal environments we recommend alligator or shell cordovan in dark tones; for operational deployment, a grey or aviation blue NATO strap maintains historical authenticity; for daily versatility, a Tuscan calf leather in vegetable tanning represents the optimal balance between elegance and practicality.

How do I change the strap on the Bremont ALT1CGNbr?

Position the watch on a protected surface, locate the spring bars on either side of the lugs and use a blunt strap-removal tool to gently lift and extract them. Insert the new strap onto the spring bars, then snap the mechanism into the lug holes. The operation requires care to prevent scratches on the bezel.

Can I use a quality aftermarket strap on this model?

Yes, provided the strap is specifically constructed for 22-millimetre lug width. Quality artisanal aftermarket straps, such as those in Italian leather with titanium deployante, guarantee total compatibility and often exceed the finishing standards of original straps.

How long does a leather strap last on a watch like the Bremont ALT1CGNbr?

Durability depends on intensity of use and tanning quality. A vegetable-tanned leather strap on a chronograph used daily maintains structural integrity between three and five years; with rotation amongst multiple straps and periodic maintenance, longevity can extend beyond seven years whilst developing an appreciable patina.
