Atelier Remontoir

Time, taken apart.

An independent atelier building mechanical calibres the slow way — every wheel cut, adjusted, and finished in-house. Scroll, and the movement will show you how it works.

Wind Down
I — The Calibre

Eighty-one parts,
one breath.

Calibre RM-03 assembled: mainplate, barrel, going train, escapement, balance. Keep scrolling — the movement will come apart in the order a watchmaker would take it apart.

II — The Barrel

Where the week
is stored.

A coiled mainspring inside the barrel drum holds five days of running torque. Every other part of the movement exists to spend that stored week honestly — at one steady rate.

III — The Going Train

Gearing the hours
down to a heartbeat.

Three wheels step the barrel's slow, heavy turn up into the fast, light rotation the escapement needs — center, third, and fourth wheels, each cut and polished in-house.

IV — The Escapement

The part that
says no.

The escape wheel wants to spin freely; the pallet fork refuses, twice a beat. That refusal — released in tiny, equal portions — is the tick. Ruby pallets keep the argument frictionless.

V — The Balance

Four hertz
of judgement.

The balance wheel and its hairspring are the movement's conscience — 28,800 oscillations an hour, each one deciding how long a second is allowed to be.

VI — Cased

Back together.
Under sapphire.

Reassembled, regulated in five positions, and sealed. What you wear is the argument settled.

The Atelier

Slow is a specification.

“A movement leaves this bench when it keeps time in five positions, not when the order book says so.”

Remontoir produces fewer than two hundred movements a year. Every wheel is cut in-house, every screw blued over an open flame, every hairspring counted and pinned by hand.

Journal

Notes from the bench.

“An atelier that treats a five-day power reserve as a moral position.”

Horological Review

“The finishing under the balance cock — where almost nobody will ever look — is the best argument for the price.”

Collected, 2025

“Slow, stubborn, and right.”
