Laco x Circula ProLab: A Rare German Tool Watch Collaboration
Laco x Circula ProLab
A Rare Collaboration in German Watchmaking
It is not often that two independent watchmakers with distinct identities come together to create something entirely new.
The Laco x Circula ProLab is one of those rare moments. Presented as a complete two watch set and limited to just 170 worldwide, it is not simply a variation or commemorative release. It is a complete project.
Two watches. Two identities. One unified concept.
What makes it compelling is not only its rarity, but the way it explores two directions of modern German tool watch design within a single release.

Two Brands, One Project
Both Laco and Circula are rooted in Pforzheim, a city long associated with German watchmaking. Each has developed its own approach to tool watches, shaped by different histories and design priorities.
What makes the ProLab notable is not simply that these two brands collaborated, but how they approached it. Rather than merging into a single compromise design, they created a set that allows each perspective to stand on its own.
The result feels deliberate. Not a marketing exercise, but a considered project.
Field and Pilot, Reinterpreted
At the center of the ProLab set is a simple idea: explore two expressions of the tool watch.
One watch leans toward the field watch. Its sand dial introduces a warmer, more relaxed character, while still maintaining the clarity expected of a purpose-driven design.

The other follows the Type B pilot watch tradition, with a more structured, instrument-like layout. It feels sharper, more technical, and closely tied to aviation heritage.

Seen together, the contrast becomes the point. Rather than choosing one direction, the set offers both.
More Than a Limited Edition
Many limited editions rely on surface changes. A different dial, a new color, or a minor variation.
The ProLab is different. It is built around concept rather than variation.
Each set is numbered, reinforcing its rarity, but the real value lies in its completeness. Two watches, two perspectives, one release.
It is rare to encounter a project that offers both conceptual depth and practical versatility in equal measure.

A Collector’s Perspective
For collectors, the distinction is clear. Some releases are variations. Others are complete projects.
The ProLab belongs to the latter. It reflects restraint, clarity, and a willingness to explore familiar design language without overcomplicating it.
For those drawn to modern German watchmaking, it is worth a closer look.
