The Flying Whirlwind

01

The Flying Whirlwind

The most beautiful of complications, at the heart of every ONE. The tourbillon counteracts the effects of gravity on the balance wheel and ensures consistent accuracy, regardless of the watch's position.

Visible at 6 o'clock, it embodies the passage of time by making a complete revolution every 60 seconds, in tireless rotation.

Its manual winding invites a simple and timeless ritual, which strengthens the bond between the watch and the person who wears it.

A compass-inspired dial

A compass-inspired dial

The “sector dial” is the signature of the ONE collection. Its hour markers, positioned according to the cardinal points, reflect the relationship between choices, direction, and the importance of time in life’s journey.

The hands also evoke a compass, guiding the wearer toward their aspirations. On the Skeleton versions, a tinted plexiglass dial offers a view of the movement.

An urban watch

03

An urban watch

Casual or dressed up, the ONE complements your everyday style. True to the colors and textures of Parisian architecture, its lines are structured, elegant, and resolutely modern.

Its 22 mm vachetta leather allows you to personalize the bracelet as you please.

Assembly in the heart of Paris

The obsession with time

The obsession with time

Captivated since childhood by the inexorable passage of time, Alexis Szewezuk naturally found refuge in watchmaking. It was this acute awareness of passing time that prompted him to found INERCY in 2020, with a genuine ambition: to design mechanical watches designed to anchor and accompany every moment of life.
