About Lagos
The openworked dial reveals the movement’s layered geometry, while the mainspring-driven transmission converts stored elastic energy into regulated rotational output. Its appeal lies in the contrast between exposed mechanical components and the disciplined arrangement required to maintain clearance, alignment, and consistent interaction between moving parts.| Reference | GM-113-11 |

Mechanism
Each Theorema timepiece brings together a complex network of mechanical components, design decisions, and technical expertise. The result is a watch that combines the intricacy of mechanical engineering with the visual character of a carefully designed instrument. Pionier’s approach is defined by modern forms, distinctive aesthetics, and demanding standards throughout the design and production process. Drawing on established European engineering traditions, the brand applies this technical heritage to its own interpretations of contemporary watch design.
