Lehmann Uhren
Lehmann Uhren is a German watch brand associated with Markus Lehmann and precision manufacturing in the Black Forest. The maker states that it has produced mechanical wristwatches since 2011. This dates watch production rather than necessarily all business activity under the Lehmann name.
INTEMPORAL and movements
INTEMPORAL includes window-date, pointer-date, power-reserve and dual-time models. The development account describes proprietary calibres, extensive in-house manufacture and technical support from watchmaker Andreas Strehler. Extensive manufacture does not establish that every component in every watch was made in the same place.
Assessment
Record the exact model, calibre, reference and execution. A function name alone cannot identify a generation. Compare servicing and original documentation with the actual watch. Do not transfer dimensions, power reserve or water resistance from newer models to other INTEMPORAL examples.
