Laco Flieger Original Speyer Auto 39mm

Laco Original Pilot Watches are authentic reconstructions of the legendary observation watches of the 1940s, also known as B-Uhr, from the German term Beobachtungsuhren. At that time, only a very limited number of manufacturers were authorized by the Reichsluftfahrtministerium (RLM), the former German Ministry of Aviation, to produce these pilot watches.
With their impressive original diameter of 55 mm, these timepieces were used as true navigation instruments. Together with IWC, Laco, Lange & Söhne, Stowa and Wempe, a watchmaking classic was created whose design has inspired countless wristwatches over the decades.
With the Pilot Watches Original collection, Laco today presents the most authentic reconstructions of this type of watch available on the market, preserving their historical essence.
In addition to the replica with the historic 55 mm diameter, the collection is offered in contemporary case sizes of 39, 42 and 45 mm. All components are proportionally adapted to each size, always based on the original historical construction plans.
The current models retain many characteristics of the historic originals, such as the iconic logo-free dial designed to avoid distractions, Type A (Baumuster A) or Type B (Baumuster B) dials, and the distinctive straight-lug case shape with a matte grey finish to reduce reflections in the cockpit.
Optimal legibility, both by day and by night, remains a top priority. While radioactive materials were used in the past, today only safe Super-LumiNova luminous material is employed. The distinctive oversized crown allows the watch to be operated easily, even when wearing gloves.
The lateral engraving “FL 23883” represents a former classification number rather than a serial number. On historic models, this engraving was located inside the case, while on current versions it is displayed on the exterior. The rivets on the leather strap, which once served a structural purpose, are now retained purely as a decorative reference to the original design.
This model is powered by the automatic Laco 200 movement, based on the reliable Sellita SW 200. The case is crafted from stainless steel with a dark sandblasted finish and features the “FL 23883” engraving. It is fitted with a domed sapphire crystal with anti-reflective coating and a solid engraved case back.
The dial features numerals and indices treated with Super-LumiNova C3, while the thermally blued steel hands are filled with the same luminous material to ensure excellent readability in all lighting conditions.
It is completed with a brown calfskin leather strap with rivets and is delivered in a watch box with an outer cardboard box included.
