U never tell us which watch is it in the end...

I do when no one has got it right. Going forward, I will post the answer even when someone has got it right. Thanks.

Thx because I am really curious and if u can also share how we can tell which watch is it

You are most welcome. I just posted the answer to this one. Unfortunately I don’t know how to guess the watch based off the features (I am not very knowledgeable about watches). I am interested in mechanical watches and have a book and I post pictures from that book.
