Eterna-Matic Super Kontiki – Black Dial 1970s Diver

One of the most iconic and criminally undervalued dive watches ever made. This is a genuine 1970s Eterna Super Kontiki with the legendary Eterna-Matic ball-bearing rotor system, the five-shield signature, and that unmistakable military black dial with oversized triangle markers. A rugged 40mm diver famously supplied to military units — including the Danish Navy — and built to survive anything.

Why this piece stands out

• Full original 1970s Eterna Super Kontiki with five-shield logo
• Matte black military dial with huge luminous triangles at 12-3-6-9
• Rare original Gay Frères–style beads-of-rice bracelet with diver’s extension
• Automatic Eterna-Matic 1423 movement with ball-bearing rotor
• Thick, unpolished case with razor-sharp geometry and original sunburst brushing
• Rotating black bezel with tritium pearl — crisp action, period-correct lume

Condition

Outstanding, unpolished, all-original survivor. Case is thick and crisp with only light honest wear — never refinished. Dial and hands have matured into a beautiful warm patina, with tritium that glows yellow-green under UV. Bezel insert is original and unfaded. Crystal shows minor surface marks as expected from original acrylic. Movement is freshly serviced and running strong at +8 sec/day. Bracelet is an original Eterna-signed BOR with minimal stretch, fits up to ~7.9" wrists.
