Hi! I have my grampas older watch and I just need more info on it, if anyone can help me out.
Its an Eterna Matic wrist watch The numbers on the back are 7026212 I'm not sure how to get the back off and dont want to scratch it. On the back is also an engraving which says 1975
1. How do I take the back off 2. Is there a place online where I can search that number where it would tell me more about this watch. 3.Is it actually 1975 4. How many jewels is it 5. An estimated price for insurance purposes.
