Catalogue description
Dealer description — Craft & Tailored
Many iconic timepieces have been closely associated with expeditions especially in the tool watch category – from the highest mountain accents to the deepest depths of the ocean even into outerspace the need for accurate timekeeping has always been a top priority. The 1947 KonTiki expedition was not setting records, it was about establishing Polynesia had been established by mankind moving from South America and not from Central Asia. The guide of the expedition wore an Eterna on his wrist and in 1958, Eterna selected the KonTiki designation for its most rugged line in tribute to Thor Heyerdahl’s odyssey. The KonTiki line of rugged dive watches were selected by adventurers and divers in late 1960 into the 1970's and this is the case specifically with the Super KonTiki which was adopted by the Israeli secret service and UDT divers three decades ago. This specific 1970's Eterna-Matic Super KonTiki IDF 200m "Civilian Non-Issued Model" military dive watch. Original condition with all functions working.

Historical context
Quartz Revolution (1969 – 1990)
Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.
Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Wristwatches
Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.
After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.
What to look for
- The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
- The calibre: its maker and number are often stamped under the dial or on the bridge.
- Originality of dial, hands and crown — refinished ('redial') dials are common.
- Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.
Dating clues
- Wire-lug cases: before c. 1925.
- Water-resistant screw-down cases: from 1926.
- Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
