Dear OF, Up for your consideration is my Eterna-Matic Kontiki 20. This reference is rather uncommon and it is safe to say that this watch is very well-built. Despite its size and weight, it wears comfortably enough. The watch is fully original including the crown and crystal. The dial is a striking purple-ish blue in sunlight, and dark blue otherwise. It has an intricate pattern. The bracelet marked HC 473 is very solid and falls comfortably around your wrist. It will fit up to approx. 19cm wrists. It is nicely brushed and in great shape. The screw down crown is unmarked as it should be. Setting the time works, as does winding and the date quick change. However the crown spring is broken and therefore it doesn't click or snap in between those actions. The case and bracelet have intricate bevels and play with the light nicely due to the brushed finishing. Sharp caseback. Some moving frames. Size: 37mm excluding crown. 45mm lug to lug. 11mm height thanks to the flat crystal.
