Type: JetFlyer Chronograph - Watch
Price: 799.00 - 849.00 (2 variants)

Inspired by Wolbrook’s adventurous heritage, the JetFlyer® Automatic Chronograph brings together the iconic proportions of the original 1950s Skindiver® case with modern French watchmaking. Designed as a true tool-watch, it combines functional chronograph capability, mechanical sophistication, and everyday durability.

The stainless steel case measures 38 mm at the bezel (37 mm mid-case) with a thickness of 12.1 mm (14.3 mm including the glass box sapphire crystal) and a comfortable 46 mm lug-to-lug length. It features a screw-down crown and caseback ensuring 100 m water resistance, drilled lugs for easy strap changes, and a 120-click unidirectional rotating bezel combining a 60-minute dive scale with a 12-hour secondary time-zone indication.

The matte black dial focuses on clarity and functionality, with two chronograph subdials (30-minute and 12-hour counters), extended markers at 3, 6, and 9 minutes inspired by traditional telephone timing intervals, and a discreet tachymeter scale. C7 Super-LumiNova® X1 grade is applied to all hands and markers, including Wolbrook’s signature arrow-shaped minute hand and oversized “lollipop” chronograph seconds hand.

Powered by the Jeambrun PS 6402 automatic chronograph movement, beating at 28,800 vibrations per hour with a 55-hour power reserve, the watch showcases modern mechanical architecture. Through the exhibition caseback, the movement reveals its distinctive Armure de France finish — an interwoven hexagonal pattern symbolizing strength, precision, and French craftsmanship.

The JetFlyer® Chronograph is paired with a two-piece rally-style leather strap crafted from Italian vegetable-tanned leather and secured with a signed 316L stainless steel pin buckle.
