Frequently asked questions

What is the lug width of the Bremont Special & Limited ALT1-B Kingsman?

The ALT1-B Kingsman features a standard lug width of 22 millimetres, measured from the inner diameter of one lug to the other. This specification is confirmed in the official Bremont documentation and requires straps conforming to this measurement to ensure lateral stability and optimal casing fit.

Which strap material is most suitable for a pilot's chronograph like the ALT1-B Kingsman?

For a pilot's chronograph with instrumental vocation, Tuscan leather or shell cordovan straps offer the patina and historical resonance of vintage cockpit instruments. Conversely, a NATO strap or satinised rubber strap maintains the sporty aesthetic without compromising the military character of the movement. The choice depends on intended wear: refined daily or direct operational use.

How do you correctly measure a watch's lug width?

Position a ruler or digital calliper perpendicular to the lug of the case. Measure the internal space between the two strap attachment points on the case, from inner edge to opposite inner edge. For the ALT1-B Kingsman, this measurement must be 22mm. Do not confuse lug width with case width.

Which aftermarket straps are compatible with the Bremont ALT1-B Kingsman?

All straps featuring a 22mm lug width are compatible. The Milano Straps collection offers Italian leather, alligator, shell cordovan, NATO, and rubber options, each ready for despatch. It is possible to personalise the buckle and select the deployant clasp in stainless steel or gold according to your preferences.

What is the lifespan of a leather strap on a daily-wear chronograph?

A Tuscan leather strap employing vegetable tanning, when subjected to daily use (wrist-worn 8–12 hours per day), achieves an average lifespan of 4–6 years, developing a fascinating patina over time. Exposure to direct sunlight, extreme humidity, and perspiration accelerates the ageing process. Rotation among multiple straps significantly extends overall longevity of the strap collection.
