i am new to this forum so please bear with me. my Partner bought me an Eterna-Matic Chronometer and I was wondering if anyone had any information on this watch? I have been in contact with Eterna/Porsche who have requested info on serial numbers but there are no eternal engravings on the case so I am going to get it opened up and see what is inside. In the meanwhile I have attached some photos. It is a very simple watch and I love the clean lines and would be particularly interested if anyone could advise on possible dates. I have looked extensively on the internet for this watch and have seen something similar style wise (but a different colour and not referring to the Jewels or Chronometer standard). I have also approached an Eterna vintage watch reseller here in the UK and they say they have seen nothing like it.
best wishes and any help or info would be appreciated
