Laco Aachen 39 mm Automatic Pilot Watch
Ref. 861990
The Laco Aachen 39 translates the distinctive Type B navigator-watch design into a balanced size suited to everyday wear. Its black dial uses the traditional arrangement of a prominent outer minute track and a smaller inner hour circle, providing the unmistakable appearance and immediate readability of a historic German pilot watch.
A matt-finished stainless-steel case, Super-LumiNova C3 markings, sapphire crystals on the front and back, and a riveted brown calf-leather strap preserve the functional character of the original flieger design. Inside, the automatic Laco 2S movement provides dependable mechanical performance, hacking seconds, and approximately 42 hours of power reserve.
Curator Note
The Aachen 39 is our choice for someone who wants authentic Type B pilot-watch character without oversized proportions. Its 39 mm case remains visually substantial because of the highly legible dial, but feels balanced and comfortable enough for regular wear.
Why Collectors Choose the Aachen 39
Historic Type B dial: The traditional navigator layout places minutes on the outer track and hours on the inner circle for quick orientation and excellent readability.
Authentic Laco heritage: Laco was one of the original manufacturers of German observation watches, giving the Aachen a direct connection to historic flieger-watch design.
Highly legible display: Arabic numerals, dial markings, and hands use Super-LumiNova C3 for strong contrast in changing light conditions.
Mechanical performance: The automatic Laco 2S movement offers hacking seconds and approximately 42 hours of power reserve.
Wearable proportions: The 39 mm case and 46.5 mm lug-to-lug measurement provide traditional pilot-watch presence in a more versatile everyday size.
