The Aachen is Laco's city-edition pilot watch named for the historic Aachen airfield, one of Germany's earliest civil aviation hubs. It delivers exactly what a German flieger should: a clean, legible dial with proper lume plots, honest proportions, and a movement that will outlast its owner. No marketing fiction, no artificial aging -- just a well-built tool watch at a price that makes sense.
Laco was founded in Pforzheim in 1925, making it one of the oldest German watch brands still producing under its original identity. During World War II, Laco was one of five manufacturers contracted by the German air ministry to produce the standardized B-Uhr pilot watches -- a lineage the brand references carefully rather than exploiting. The city-edition series, of which the Aachen is part, ties each reference to a specific German airfield or aviation city, giving each watch a geographic anchor beyond generic pilot styling.
Aachen's connection to German aviation history goes back to the early days of civil flight, which earns the name rather than just borrows it. Laco has remained a mid-tier independent, building watches in Germany with off-the-shelf Swiss movements -- a pragmatic choice that keeps prices honest without pretending to be something it is not.
The ETA 2824-2 is a reliable workhorse but it is not exclusive -- you will find it in watches at every price point, and Laco does not modify or regulate it to any stated specification, so timekeeping performance varies unit to unit. The 42mm case is on the larger end for a flieger; buyers expecting the compactness of a vintage B-Uhr will find this oversized relative to those references. Lume application on the Aachen is distinctive (the original triangular Laco plots rather than the more common B-Uhr style), which some collectors appreciate and others find less authentic.
The crystal is mineral rather than sapphire, which keeps the price down but means it will scratch with regular wear. Secondhand availability is thin compared to more-marketed German pilot brands, so finding a used example in excellent condition takes patience.
New Aachen 42mm references sell in the 400-600 EUR range from authorized dealers, which is fair for a German-assembled watch with an ETA movement and 100m water resistance. The secondhand market is quiet -- Laco does not have the collector following of Sinn or Nomos, so used examples sometimes trade below retail, which is an opportunity for buyers who have done their research. Laco does not command a resale premium, so buy it to wear, not to flip.
The ETA 2824-2 is one of the most serviced calibers in the world -- any competent watchmaker can overhaul it, source parts, and regulate it without needing to touch the manufacturer. Recommended service interval is every 5-7 years under normal wear. Laco offers factory service through its Pforzheim operation, but independent service is straightforward and often faster.
