Rare Vintage DIFOR Suisse Chronograph – Solid 18K Yellow Gold – Landeron 189 with Date – Mint Condition Description: An exceptional find for high-end collectors: a vintage Difor Suisse chronograph in solid 18K yellow gold. This timepiece is a rare "Full Complication" variant for its era, featuring not only the chronograph functions but also a date window at 6 o'clock. The watch is a heavyweight in its category, with a solid 18K gold case weighing approximately 15-16 grams (net gold weight of the case). It is powered by the highly sought-after Landeron 189 movement, the specialized date-version of the legendary Landeron family.
