FROM PASSION TO LEGEND
The Laco pilot watches Original are faithful recreations of the legendary observation watches, also known as B-Uhren (German: Beobachtungsuhr), from the 1940s. At that time, only a small number of highly distinguished manufacturers were authorized to produce these pilot watches according to the exacting specifications of the German Air Ministry. With an impressive diameter of 55 mm, they served as indispensable navigation instruments. Among these esteemed companies were IWC, Laco, Lange & Söhne, Stowa, and Wempe—pioneers who set a milestone in watchmaking history, establishing a standard for precision and functionality that endures to this day.
A LOVE FOR THE ORIGINAL
With the Original series, Laco brings the essence of the historic observation watches into the present day. Staying true to the details of the original blueprints, we have preserved their defining features across the available case sizes, ranging from 39 mm to the original 55 mm version. Each size has been carefully adjusted to maintain the proportions of the historical models, ensuring their authenticity is evident in every piece.
This page provides an overview of the individual elements of the pilot watches Original and showcases how meticulously each component has been crafted to honor the legacy of the originals.
FunktionalitY in FoCus
Looking back at their remarkable history, pilot watches were specifically designed to meet the demands of aviation. They combine features that were essential then and remain so today: durability, functionality, and clear, intuitive readability. Resistant to shocks, vibrations, and pressure, and reliable even under varying light conditions, they were indispensable tools for pilots. These qualities continue to make pilot watches practical companions for everyday use. Anyone choosing a Laco in the classic pilot watch design benefits from exceptional handling, superior craftsmanship, and precise timekeeping.
FAITHFUL CASE DESIGN
The case stays true to the form and details of its historical predecessors. The distinctive straight lugs, with their unique design characteristic of pilot watches, emphasize the authentic aesthetic. The matte grey surface, originally developed to prevent reflections in the cockpit, is now achieved through a high-quality dark sandblasting process.
The proportions remain faithful to the historical models and have been carefully adjusted to suit the modern case sizes.
„FL 23883“
The engraving “FL 23883” on the case flank refers to the original military classification of observation watches.
“FL” stands for “Fliegerei” (aviation), while the numbers specify the device type: “23” classified navigational instruments, and “883” identified the specific type, the pilot watch.
This marking is not a serial number but a unique designation that signified compliance with the strictest military standards.
ICONIC DIALS
The dials are designed in the historical type A and type B layouts to ensure optimal readability. Type A features a clean layout with hour markers from 1 to 11, while the 12 o’clock position is highlighted by a prominent triangle with two dots. In contrast, the type B displays minutes in 5-minute increments on an outer ring, with an inner circle marking the hours from 1 to 12.
In homage to the historical observation watches, we deliberately forgo a logo or the “Made in Germany” inscription on the dial to maintain a clear and uncluttered appearance. This focus on essential elements, combined with the characteristic pilot triangle at 12 o’clock, ensures the wearer can instantly and precisely read the time at a glance.
Superluminova C3
For optimal readability at night and in low light, the harmless luminescent material Superluminova C3 is used today. It emits a greenish glow in the dark, offering maximum luminosity and visibility. In the past, radioactive radium was used, but it has been replaced with this safe alternative.
On the type B dial, as with the historical models, only every second numeral on the outer ring is intentionally coated with luminescent material.
HANDS
The distinctive frame hands also remain true to the historical models and are precisely adapted to the respective dial types.
The hour and minute hands are coated with Superluminova C3, which emits a greenish glow in the dark. Their frames are thermally blued - a meticulous finishing process, just like in the original models, achieved by heating the steel to around 300 °C. This technique not only gives the hands their signature blue color but also provides exceptional corrosion resistance and durability.
Another notable detail is the hole in the counterweight of the second hand, a feature inspired by historical pilot watches.
CROWN
The crown is a distinctive feature of pilot watches, designed specifically for easy handling—even when wearing gloves. Its textured shape and generous size reflect the functionality that was indispensable for pilots.
On historical observation watches, a small spacer between the crown and the case was included to further simplify operation. For our standard models, we omit this feature in favor of greater wearing comfort. However, for those seeking full authenticity, this spacer can be selected as an optional upgrade.
CASE BACK ENGRAVING
The case back marking, featuring the instrument number, manufacturer, and movement designation, is another detail that emphasizes the connection to the historical observation watches.
While it was hidden inside the case back on the historical models, it has been deliberately moved to the outside on our modern versions - visible to the wearer and serving as a tribute to tradition.
A Brief History of Navigation
The Laco pilot watch, particularly the observation watch model, was an essential navigation tool for navigators. These watches were specifically designed to meet the demands of aviation and were a key part of the equipment used in flight.
How navigators used the Laco pilot and observation watch for navigation:
1. Timekeeping and Flight Planning: The Laco pilot watch enabled precise timekeeping, which was crucial for flight navigation. Pilots and navigators used the watch to monitor takeoff times, planned flight durations, and stopovers.
2. Speed Calculation: By combining the watch with established navigation methods, such as measuring distance and time, pilots could calculate their aircraft's speed. This was vital for accurately estimating positions during the flight.
3. Position Determination: Using the accurate time provided by the watch and the sun's altitude, navigators could determine the aircraft's position through astronomical navigation techniques, such as solar navigation. The watch served as a time reference for these calculations.
4. Coordination of Flight Maneuvers: Pilot watches were also used to provide precise timing for planned flight maneuvers and course changes. This was crucial for avoiding collisions with other aircraft and maintaining an accurate flight path.
5. Flight Monitoring and Time Intervals: Pilots and navigators used the Laco pilot watch to monitor specific time intervals, such as radio communication, weather updates, or navigation points. This helped organize the flight efficiently and manage unforeseen events effectively.
The Laco pilot watch played a pivotal role in flight navigation. Its precision and reliability made it an indispensable tool for early aviation, where challenging conditions required accurate navigation instruments.
