JETFLYER CHRONO-AUTOMATIC - OVERVIEW

COMPACT. BALANCED. FUNCTIONAL.

The JetFlyer combines compact ergonomics with true instrument presence. Its 38 mm case (37 mm mid-case) and slim 12.1 mm profile (14.3 mm including the glass box sapphire crystal) are carefully proportioned for comfort and stability on the wrist.

The short lug-to-lug distance ensure a secure and natural fit across a wide range of wrists.

A tool chronograph built to be worn — comfortably and without compromise.

JETFLYER CHRONO-AUTOMATIC - OVERVIEW

DESIGNED FOR IMMEDIATE READING

The JetFlyer Automatic Chronograph is built around a clear principle: prioritizing information.

The oversized 30-minute counter — the Big Eye — draws attention to what matters most. The rest follows: central chronograph seconds, signature arrow minute hand, and a secondary 12-hour counter.

A discreet tachymeter and a dual-scale bezel add functionality without compromising clarity.

Nothing competes. Everything serves a purpose.

POWERED BY THE JEAMBRUN PS 6402

At the heart of the JetFlyer® Automatic Chronograph is the Jeambrun PS 6402 — a modern column wheel chronograph movement built on a proven architecture.

Beating at 28,800 vibrations per hour with a 55-hour power reserve, it delivers precise and stable chronograph operation.

Each movement is assembled, adjusted, and regulated in France, ensuring a high level of control and consistency. Through the exhibition caseback, the PS 6402 reveals its distinctive construction, including a skeletonized balance bridge, blued screws, and the Armure de France finish — an interwoven hexagonal pattern.

A chronograph movement designed as a foundation — robust, accessible, and built to support a new generation of mechanical complications.
