The Singer Caballero, the Brand’s Take on a Time-Only Watch with the New Calibre-4

Singer Reimagined has spent the past eight years experimenting with what independent watchmaking can look like. The Geneva-based brand, founded by Rob Dickinson of Singer Vehicle Design and designer Marco Borraccino, established its name with the radical Track 1 chronograph, powered by Agenhor’s Agengraphe. It was followed by the stripped-down Flytrack, the diving-oriented Divetrack, and the compact, helmet-style 1969 Chronograph and Timer, both powered by variations of Agenhor’s architecture. Most recently, Singer embraced its “restomod” DNA with the Heritage Collection Chronograph, housing restored Valjoux 236 calibres in a vintage-inspired two-register layout.

With the new Singer Caballero, the brand steps into a new territory: a time-only, daily-oriented watch. It is the brand’s first creation to be powered by a proprietary calibre, the Calibre-4 Solotempo, and it demonstrates that Singer’s obsession with design and mechanics extends beyond sports-inspired chronographs. As its name suggests (Caballero, Spanish for gentleman), this new line appears to be about quiet confidence and horological substance beneath a deceptively simple, yet recognisably Singer exterior – in particular the 1969 collection and Heritage Chronograph.

The Singer Caballero stainless steel case measures 39mm across and is 10.5mm thick. It is slim, though not quite under the magic 10mm mark that would have pushed it deeper into everyday dress-sport watch territory. Its architecture is composed of three distinct sections: a brushed mid-case, polished chamfers, and a domed sapphire crystal that softens the profile, with a signature fluted bezel. A sapphire caseback reveals the movement, and the watch is water-resistant to 50m. 

The dial is executed without the indices in multi-layer lacquer, available in Piano Black, Empire Green or Petrol Blue. A golden-toothed flange, an applied Singer logo, and polished rhodium-plated hands, filled with orange Super-LumiNova for enhanced legibility, complete the restrained yet distinctive look. Apertures reveal the four rubies of the movement’s barrels, subtle reminders that this is not a conventional three-hander.

At the heart of the watch is the brand’s first proprietary movement, the Calibre-4 Solotempo. Developed from the ground up, it uses four barrels arranged in two parallel sets, delivering a six-day power reserve with a flat torque curve. Running at 28,800 vibrations/hour, it is engineered for stability and long-term precision, ensuring amplitude remains constant across the entire reserve. Bridges are rhodium-plated and finely finished with micro-blasting and polished chamfers.

The Singer Caballero is offered on straps in deep blue leather, khaki textile, or black textile, tapering from 20mm to 16mm at the stainless steel pin buckle. A steel bracelet option would have added versatility, but for now, Singer keeps things focused on straps. The price is CHF 17,500 (excl. taxes), production is limited.
