The Ascent in motion

— 01 · CASE

An origami case, cut from angles

Round was boring; the octagon belonged to someone else. The Ascent's decagon case is built from edges and facets, each machined and polished separately so it catches light the way brushed steel never could.

— 02 · FINISH

Stepping Stone Bracelet

Inspired by stepping stones to a summit. Our bracelet costs more than our case. It's designed for comfort, durability, and seamless flow from wrist to hand. Features screws for easy sizing and half-links for the perfect fit.

— 03 · BRACELET

Slate Stone Dial

Sandwich construction inspired by slate stone. The dial features Super-LumiNova filling for visibility in low light. A refined design that balances aesthetics with practical functionality for everyday wear.

Micro Adjust Clasp

Spring-loaded clasp that self-adjusts up to 4mm to your wrist. No need for traditional micro-adjust links. The clasp provides seamless comfort throughout the day with automatic micro-adjustments.

It lives in that genre and adds to it — the emphasis is on the bracelet. If you already own one, the Ascent is the interesting one.

The origami case is built from edges and angles. Polish is what makes them catch light; brushed steel would not.

A nitriding treatment takes surface hardness to ≈800 HV — about four times standard steel — so it keeps its shine.

Stepping stones to a summit. Our bracelet costs more to make than the case, flows off the case, and sizes with screws plus a half-link.

A La Joux-Perret G100 with date — thinner shell, longer reserve, serviceable by any watchmaker. Regulated before assembly.

Better: the clasp is spring-loaded and self-adjusts by up to 4mm as your wrist changes.

We made it as thin as practical use allows. The sandwich dial set the floor.

Each model carries design, engineering and prototyping cost before a watch exists. The margin lets us support you without going bankrupt.

Lead times on movements, cases and bracelets run five months or more, and a new brand cannot jump the queue.

Our first release, built around the bracelet, the case and the dial.

Never. Discounts hurt the people who paid full price and drain the R&D budget for the next watch.

Reserve your Ascent.
