Frequently asked questions

What is the lug width of the Bremont Solo37SiRg?

The Bremont Solo37SiRg features a lug width of 20 millimetres. This dimension was selected to maintain ideal proportions between the 37mm case and the strap, ensuring both aesthetic balance and optimal ergonomics. To verify strap compatibility, measure the distance between the two attachment holes using a digital calliper.

Which strap is recommended for the Bremont Solo37SiRg?

For the Solo37SiRg we recommend an alligator strap of superior quality for formal wear, or vegetable-tanned calf leather for daily versatility. Both materials dialogue with the understated stainless steel case. For more sporty use, a NATO strap offers practicality without stylistic compromise. All straps must feature a 20mm lug width to ensure precise fitting.

How do you change the strap on a Bremont Solo37SiRg?

To change the strap on the Solo37SiRg: 1) obtain a dedicated spring bar removal tool; 2) position the watch with the case facing upward; 3) insert the flat end of the tool into the spring bar access hole, pushing gently to release the return spring; 4) remove the old spring bar and strap; 5) insert the new strap and spring bar, ensuring the spring is correctly positioned. This operation requires care to avoid scratching the case.

Can an aftermarket strap be fitted to the Bremont Solo37SiRg?

Yes, it is entirely possible to fit quality aftermarket straps to the Solo37SiRg, provided the lug width is exactly 20 millimetres. Artisan-produced straps often guarantee superior quality compared to standard manufacturer-supplied straps, offering noble materials such as alligator, shell cordovan, or vegetable-tanned leather. Ensure the strap is constructed with robust stitching and without manufacturing compromise.

What is the lifespan of a leather strap on the Bremont Solo37SiRg?

A superior quality leather strap (alligator or vegetable-tanned calf) fitted to a Bremont Solo37SiRg has an average lifespan of 3-5 years with daily use, extendable to 7-8 years with proper maintenance. Longevity depends on factors including ambient humidity, frequency of use, direct sun exposure, and periodic application of leather conditioners. A NATO strap in robust canvas lasts indefinitely, whilst a vulcanised rubber strap has a lifespan of 5-7 years before material degradation begins.
