The Solo Solo37RG, seen from the bench

The Bremont Solo 37 Two Tone features a 37 mm case combining 18-carat red gold with stainless steel, powered by the in-house BE-36AE automatic chronometer-certified movement with hours, minutes, seconds, date, and day display. The watch has a 20 mm lug width and exemplifies Bremont's contemporary British watchmaking with a sapphire caseback revealing the Côtes de Genève decoration, screw-down crown at 3 o'clock, and minimalist dial with Arabic numerals. The two-tone aesthetic—satin red gold and polished steel—creates a balanced design for the modern wrist, with proportions integral to the Solo collection's golden ratio architecture.

Frequently asked questions

What is the lug width of the Bremont Solo37RG?

The lug width of the Bremont Solo37RG is 20 millimetres. This specification is standard across the model and accommodates any aftermarket strap equipped with 20mm lugs or passants. To verify compatibility, measure the thickness between the lugs using a digital calliper, positioning yourself on the inner base of the case.

Which leather strap is most suitable for the Bremont Solo37RG?

For the Solo37RG, we recommend Mississippi alligator for sartorial classicism: the natural scutellated grain develops rich patina over time. Alternatively, vegetable-tanned calf offers organic daily stratification, whilst Japanese shell cordovan provides structural rigidity and profound colouration. The choice depends on desired patina evolution: cordovan for rapid and dramatic change, alligator for refined, durable maturation.

How do you change the strap on a Bremont Solo37RG?

The Bremont Solo37RG employs standard 20mm spring bar lugs. Position the watch with the lug pin facing upward. Using a spring bar tool, compress the internal spring mechanism slightly and slide the old strap outward. Insert the new strap by aligning the lugs with the seats and press until the locking click engages. The procedure requires approximately two minutes for experienced users.

Is an aftermarket strap compatible with the Bremont Solo37RG?

Yes, any strap equipped with 20-millimetre lugs or passants is fully compatible with the Bremont Solo37RG. We recommend materials of comparable quality to the case: noble leathers with hand-finished detailing, buckles in tempered stainless steel or brass, passants in double-thickness leather for structural stability. Avoid rigid steel-lugged straps that cannot be adjusted, as these may stress the original seats.

What is the lifespan of a leather strap on the Bremont Solo37RG?

A leather strap's durability varies according to material and daily wear. Mississippi alligator in natural relief lasts 8–12 years with controlled usage and regular maintenance. Vegetable-tanned calf has an average lifespan of 5–8 years before visible signs of wear appear. Shell cordovan, being more resilient, may last 10–15 years. The determining factor is frequency of wear, exposure to moisture, and annual conditioning with natural oils.
