Like the clock, the Tourbillon Souscription features a tourbillon and an off-centre dial for the time that sit under a bulbous crystal to accommodate the architectural dial. The Tourbillon Souscription is made by Cools himself using traditional tools, with a good deal being fabricated by hand, as they would have been in the 19th century. Especially unusual is the lack of a crown; instead the watch is set and wound by two recessed tabs on the back of the case. 

The Rémy Cools Tourbillon Atelier in Rose Gold exemplifies fine independent watchmaking, blending traditional craftsmanship with contemporary refinement. Its polished rose gold case highlights the intricate, hand-finished details of the open-worked movement, where the tourbillon takes centre stage. Designed for precision, the watch showcases meticulous finishing—from brushed bridges to delicate anglage—creating a harmonious interplay of textures. Each detail reflects Remy Cools’ dedication to artisanal horology, offering a sophisticated yet immersive experience.

In contrast, the Tourbillon Atelier in yellow gold channels classic watchmaking heritage with a modern sensibility. The luminous yellow gold case frames a masterfully constructed tourbillon, revealing the dynamic movement beneath. Thoughtfully executed finishes, including polished and matte surfaces, enhance its depth and presence. With its balanced proportions and meticulous detailing, the watch embodies haute horlogerie’s essence—merging technical brilliance with artistic expression in a piece that captivates at every glance.
