For sale is a stainless steel Eterna from 1945. The case is "waterproof" and 33 mm in diameter. Movement is Eterna's manually wound caliber 1079. The dial is two-toned with a contrasting minute track. The radium numerals, and hands, are intact and a nice shade of green. The crown is correct. The watch runs but a service is recommended for regular use. Price is now $225 (USD) plus shipping, no returns.

Stupidly undervalued. I own several similar ones, or would have snapped it up already. Eterna remains one of, if not the most undervalued brands in the vintage market.
