European Watch Clock and Jewellery Fair 1992 BE 101
These extra-slim but water-resistant wristwatches feature fluting executed entirely by hand. The dial ring carries twin “jump-track” tone on tone grooving and the dial centre itself is stamped with small lozenge patterns. Cases and bracelets are 10-micron goldplate, with sapphire crystals.
