Brand vibe
Munich's Theorema makes deliberately large, deliberatley ornate mechanical watches... 43-45mm skeletons, dual-time city models and a tourbillon... with exposed movements and city-named collections rather than tool-watch restraint. The Istanbul is a stunner in my book. Just don't call it Constantinople.

EU is capped at 10% total including MFN duty under the Section 301 forced-labor tariffs effective July 24, 2026. With a ~6% HTS base rate, the incremental Section 301 duty is 4%.
Tariffs are assessed based on where the watch is assembled, not where individual components originate. A watch with a Japanese movement assembled in the US incurs no import duty.
