ProLab brings this shared mindset to life: two brands, two approaches, and one understanding of quality and heritage. It is a project that shows what can emerge when tradition isn’t preserved as a snapshot in time, but evolves - shaped by honest design, a genuine closeness to the community, and the confidence to simply act instead of overstate. ProLab isn’t a grand gesture. It is the natural continuation of what both brands have stood for over many years.
When values, tradition, and heritage come together, something truly unique emerges.
Watchmaking in Pforzheim has many facets—two of them are Laco and Circula. For decades, both brands have followed their own path, shaped by craftsmanship, consistency, and a clear understanding of what makes a good watch. Such values don’t arise overnight. They grow over generations, shape identity, and guide every decision we make today.
The ProLab Sand combines the distinctive case of the Laco PRO series with a warm dial inspired by classic fieldwatch design. The dark sandblasted 40 mm stainless-steel case features Laco’s signature matte finish, reducing reflections and giving the watch its distinctively rugged character. With 20 ATM water resistance and a screw-down crown, it remains reliably capable in any situation.
The sand-colored dial draws on the design language of the Circula ProTrail series: a fine circular texture at the center, surrounded by calm, matte surfaces that ensure clear orientation. The entire outer ring is coated with Swiss Super-LumiNova Old Radium, creating a warm and even glow in the dark. Thermally blued hands with BGW9 luminous material provide a precise, cool contrast.
The result is a contemporary fieldwatch with a warm, individual character -combining functionality with an unmistakable aesthetic touch.
The ProLab Schwarz combines the distinctive case design of the Circula ProTrail series with the clear visual language of a classic Type B pilot’s watch. The 40 mm stainless-steel case is specially hardened to 1,200 Vickers, giving it exceptional scratch resistance- ideal for everyday use. A screw-down crown and 15 ATM water resistance further emphasize its functional character.
The deep black dial follows the traditional layout of historical observation watches: minutes on the outer ring, hours 1–12 on the inside. Despite its classic structure, the dial gains a modern, individual expression through the striking Circula typography and the fine circular texture at its center. Swiss Super-LumiNova BGW9 on numerals, indexes, and the thermally blued hands ensures impressive luminosity and excellent legibility in any light.
A contemporary interpretation of a pilot’s watch with tool-watch character and a crisp, cool aesthetic that reaches far beyond pure function.
