I'm having trouble finding exactly what model this Eterna Matic is. I've found models thar are almost the same, but it's always something that differs. Has anyone got a clue? It's about 32mm.
Hello @Chrizg and welcome to the forum! Your watch is simply an "Eterna-matic" made famous by the use of ball bearings in the rotor system. I suspect the red second hand is an aftermarket change. If you are able to have the watch opened, you should find a serial number and a movement number inside, either of which can be used to help date your watch.
