Welcome here, first! And double congratulations for this great find. you certainly noticed that they are not totally twins, since the Steel doesn't have the same case than the gold ones.

So happy to find the twins and the gold one with box and paper 😁 ...

Thank you for your welcome. ☺️ Not totally twins you are right!

What year are these from? I also love the strap you have on the steel piece.👌🏽

Thank you! 1964 for the gold one but I don t know for the steel.
