Laco Aachen Blaue Stunde 39 Automatic Pilot Watch
Ref. 862103.2 · Type B Dial · Made in Germany
The Laco Aachen Blaue Stunde 39 brings a more expressive character to one of Laco's classic pilot-watch designs. Its deep blue sunray dial changes with the light, shifting from a restrained midnight tone to a vivid blue shimmer inspired by the brief “blue hour” after sunset.
The historic Type B navigator layout preserves the strong cockpit readability expected from a German flieger watch, while the balanced 39 mm case makes the design easy to wear every day. A grey two-piece nylon strap keeps it light and relaxed, and the sapphire exhibition caseback reveals the automatic movement inside.
Why This Model Stands Out
Many pilot watches stay close to traditional black-and-white instrument design. The Blaue Stunde keeps the authentic Type B architecture but adds depth, movement, and personality through its sunray blue dial—all in a wrist-friendly size that does not sacrifice genuine flieger presence.
Why Collectors Choose the Aachen Blaue Stunde 39
Light-shifting blue sunray dial: Rich color and visual depth make the watch distinctive without compromising pilot-watch clarity.
Authentic Type B navigator layout: The inner hour scale and prominent outer minute track deliver unmistakable cockpit character.
Wearable 39 mm proportions: A balanced alternative to oversized flieger watches, with a manageable 46.5 mm lug-to-lug measurement.
Reliable automatic movement: The Laco 2S is based on the Miyota 82S0 and offers automatic and manual winding, hacking seconds, and approximately 42 hours of running time.
Built for everyday enjoyment: Sapphire crystal, an exhibition caseback, Super-LumiNova C3, and a light two-piece nylon strap make it practical as well as visually compelling.
German pilot-watch heritage: Made in Germany by Laco, a historic name in aviation-inspired watchmaking since 1925.
