For sale is an Eterna Kontiki 20 featuring an automatic movement and a screw-down crown.

The case and dial are in nice vintage condition (see photos below). The watch winds and runs fine and seems to keep time to the minute but wasn’t checked for accuracy. While the service history is unknown, a service is recommended. With a 36 mm diameter (excluding the crown), it wears larger than typical vintage watches.

The watch is located in Switzerland and is priced at CHF 450, including shipping to most global destinations.

Watch is sold head only. Returns accepted only if the watch does not match the description or pictures.

I have references here on OF and on German uhrforum.de
