Thank you for your help!

Yes, sir. I have a good clue of the market where I live. Fair estimates, left to right, price in euros:
2-400
5-600
6-800
5-700
2000
350
2000

What I’m curious about is how an international market values these, higher or lower? Some are more sought after internationally.

That would probably be right for the 136.0104, if it wouldn’t be with og bracelet. I’d still say 500+ since condition of both case and bracelet is near pristine.
But I noticed that 166.0169 float around on sales sites for everything from 500-1300€. Not a single one sold for much less than 500€ last five years on C24. With the burgundy dial landing on the upper scale.
C-shaped Connie probably right price both here and internationally.
The Railmaster frequently hits 2,5k and above in sales price so maybe 2k is a small underestimate.
Flat Jedi, consistently 3k past three years.

EBay. Check out completed auctioned similar watches. Compare condition. Add/Minus depending on the condition comparisons.

Real values are based on want. Want = money. Don’t want =😟
