Come on man, all the info you need to identify this watch is right there. Literally just google “Tag heuer calibre 5”. This isn’t even some rare watch by some long defunct company

Because of that white blob at the top side of the dial and what appears to be some text below it, I’m gonna assume it’s a Rolex

I think I remember reading elsewhere about jomashop if it doesn’t say in stock for a watch, don’t order it, as they’ll accept the order and keep you waiting while they try to source a watch from one of their sources, which they have no clue when that’ll happen. I could be misremembering though

The right subdial appears to be a 24-hour subdial, and the left subdial is probably for telling the minutes elapsed when using the chronograph functionality

In that price range you’re best bet is probably some cheap Chinese pocket watch off alibaba/aliexpress.

Have a look at the caseback, maybe you’ll find the details there.
