Luca Soprana — Mécanique d'émotion
Soprana × Esposito
Nagoma by Luca Soprana and Emmanuel Esposito

Nagoma.
Two makers.
One language.

The first collaborative creation between Luca Soprana and Emmanuel Esposito — two Italian master craftsmen from different disciplines, brought together by a shared philosophy of making.

Not a watch, and a knife.
A single vision.

« When two craftsmen share the same language, something rare becomes possible. Not a language of words, but of tolerances, surfaces, restraint — the quiet pursuit of perfection. »

Years of parallel devotion — and a deep mutual admiration for each other's work — brought Luca Soprana and Emmanuel Esposito together. What emerged is not a watch accompanied by a knife, nor a knife designed to match a watch. It is a single vision, expressed through two highly precise and entirely handmade mechanical objects.

The name carries their philosophy. Rooted in Japanese culture, Nagoma reflects a vision where complexity is embraced but reduced to its essence. What remains, once everything unnecessary has been removed, is not simplicity. It is clarity.

Each set is entirely unique. The mother-of-pearl mosaic at the heart of each object is composed of individually hand-sorted fragments, each chosen for the singular way it captures light. No two compositions will ever be the same — each creation carries its own personality, and its own story.

Built upon the Time Only.

The Soprana Nagoma is built upon the Soprana Time Only — Luca's first watch under his own name: a three-hand dress watch created in microscopic numbers, with one ambition only — to perfect the essential. For Nagoma, that philosophy becomes a point of encounter. Every choice follows the same logic: restraint, coherence, and absolute respect for the integrity of the object.

Nagoma brings a new material and emotional dimension to the Soprana universe — while remaining fully aligned with its values: precision, depth, and the pursuit of lasting beauty through honest construction.

Key elements.

Three pillars
Revised LSTO calibre — Nagoma
№ 01

A revised LSTO calibre

At the heart of Nagoma beats the hand-wound Calibre LSTO, designed and manufactured entirely in-house in Vaumarcus. Its architecture: a large balance wheel, a mirror-polished steel balance bridge, an in-house hairspring with Breguet overcoil.

Nagoma case — 38.8mm
№ 02

A sleek case

The 38.8 mm case, standing just under 10 mm thick, reflects Luca Soprana's deliberate commitment to the classical proportions of the great twentieth-century dress watches. Restrained, elegant, perfectly balanced on the wrist.

Nagoma mother-of-pearl dial
№ 03

A MoP dial

The dial is the visual signature of Nagoma. Individually hand-sorted fragments of black-lip mother-of-pearl, cut and arranged one by one. Its mosaic surface constantly shifts between darkness and light — a unique, living presence on the wrist.
