Kalle Slaap presents a breathtaking 1940s Vacheron Constantin deck watch originally used by the British Navy on submarines during World War II. He uses a microscope to reveal the movement’s “insane” level of craftsmanship, highlighting features such as the temperature-compensated bimetallic balance wheel, a perfectly polished swan-neck regulator, and hand-finished clicks and springs. Kalle expresses profound admiration for the invisible details, like the seamless fit between plates and the mirror-polished screw tips, which were achieved decades before the use of modern production technology. The presentation serves as a masterclass in horological finishing, demonstrating why this particular timepiece stands as the pinnacle of historical watchmaking excellence.
