Nantes Watchmaking House

Akrone

French watchmaking without compromise

Create without following.

Akrone, founded in 2015 by Jean-François Kerboul and Erwan Kerneur, bears a name inspired by the Greek "achrone," meaning "out of time." The "K" is a nod to our initials. In Nantes, our team—designers, watchmakers, and project managers—crafts each watch with the same high standards: to create unique, timeless, and resolutely French pieces.

Leader in France

€100,000 in donations donated

More than 100 projects for the army (ALAT, Foreign Legion, PSIG, etc.) and civil aviation (Transavia, Air France, Air Corsica, etc.) demonstrate our expertise and commitment in this demanding field.

Some projects incorporate a charitable dimension: at the request of the units, a portion of sales is donated to military aid associations. To date, more than €100,000 has been raised.

Our workshop

At the heart of know-how

Our workshop, located in Nantes, is the heart of our expertise. Technical conception, design, assembly, adjustments, and quality control are carried out here with the highest standards. Our team—four trained watchmakers and one designer—uses this expertise to successfully complete each custom watchmaking project, even the most technical and ambitious.

Recognized calibers

At the heart of know-how

In our workshop, we prioritize precision and reliability. We select Swiss, French, and Japanese automatic movements—Sellita, Soprod, France Ébauches, and Miyota—which we rework in-house to adapt them to our standards and the constraints of each project. Each caliber is carefully adjusted and decorated, with attention to every detail.

Solid by nature

The essentials, at the right price

Our watches combine proven technical choices with leading materials—titanium, 316L steel, ceramic, carbon—selected for their performance and longevity. Every feature is field-tested, every detail designed to last. This commitment allows us to offer reliable, uncompromising watches at some of the fairest prices on the market.

the avant-garde of watchmaking

The brand with multiple records

Akrone is a know-how and records that speak for themselves. The first French watchmaking Kickstarter in 2015, which paved the way for a whole generation of new French watch brands. Two diving records with Frédéric Swierczynski. Vipère de Besançon certification. French leader in custom-made watches for the armed forces. Unique creations based on artistic crafts with Thomas Brac de la Perrière and official timekeeper of the prestigious Solitaire du Figaro sailing race for three editions. Over the past ten years, we have worked tirelessly to share our vision and passion for watchmaking. As we approach our tenth anniversary, new projects will enrich this history and these records.
