Nantes Watchmaking House

Akrone

French watchmaking without compromise

Create without following.

AKRONE is above all a story of passion.
Launched in 2015 by Jean-François Kerboul and Erwan Kerneur, the brand's name is inspired by the Greek achrone , meaning "out of time." The "K" replaces the "ch" in a nod to our initials.

Everything happens in Nantes, in our workshop.
Design, assembly, adjustment, quality control, after-sales service: every step is carried out here.
Each watch is unique and meets our requirements for quality and reliability.

AKRONE, “timeless” watchmaking, designed by enthusiasts for enthusiasts.

Leader in France

€100,000 in donations donated

For several years, AKRONE has been working directly with the army — ALAT, Foreign Legion, PSIG, BRI, GIGN — as well as with civil aviation , such as Transavia, Air France or Air Corsica. These collaborations are born from exchanges with users to design robust , precise and reliable watches, perfectly adapted to their conditions of use.

When the project leader so wishes, a donation is made to military aid associations . More than €100,000 has already been donated—a simple gesture that is part of our commitment.

Recognized calibers

At the heart of know-how

The calibers used are carefully selected from proven references such as Sellita, Soprod, France Ébauches and Miyota, for their robustness. Each movement is then optimized in-house, with a custom calibration adapted to the requirements of the field.

The adjustment follows rigorous protocols, inspired by the Viper Seal of Besançon, to ensure optimal precision. Our watches are also field-tested, where their performance, stability, and reliability are validated in real-life conditions.

Finally, the finishes are not left to chance: the oscillating masses are optimized internally and benefit from personalized decorations.

Key points:
Robust and proven calibers
Custom optimization and calibration
Rigorous adjustments according to the equivalent chronometric certification.
Tests in real conditions
Custom finishes and decors

Solid by nature

The essentials, at the right price

The materials used are carefully chosen for their robustness and durability: titanium, 316L steel, ceramic and carbon, often from recycling channels dedicated to watchmaking.

Each model is tested in the field, in real conditions, by professionals, elite units, divers, civilian pilots, to meet precise specifications adapted to each use.

The finish is meticulous, with rigorous assembly and quality control at each stage.

All this, with one of the most competitive quality-price ratios, given our expertise and the technical choices we make.

Key points:
Robust materials
Real-life testing by professionals
Careful finishing and strict quality control
Excellent value for money

the avant-garde of watchmaking

The brand with multiple records

Since 2015, AKRONE has launched the first French watchmaking Kickstarter , paving the way for a new generation of watch brands in France.

Here are some key steps in our journey:
Two diving records with Frédéric Swierczynski
Viper Certification awarded by the Besançon Observatory
Official chronometer of the Solitaire du Figaro for three editions
Recognized leader in custom-made watches for the armed forces
Collaborations with craftsmen, notably Thomas Brac de la Perrière

Since 2023, AKRONE has been working with France Ébauches to promote the return of Made in France mechanisms and is part of the Fédération de l'Horlogerie to support the French industry.

In ten years, AKRONE has built an independent, demanding, and expertise-driven brand. New projects are already underway.
