Hi Art,
you have got a beautiful piece, congrats!
There is little to advice:
1) try to find a plain crown - as far as I can guess from the picture it has an Omega symbol on it - this is a later replacement!
This should not be an issue as the crowns were only gold plated, not solid gold, even on the chronometers.
2) Do not bother about a solid gold buckle! Even on these chronometers there have not been solid gold buckles at that time, only gold plated ones!
But these original buckles are hard to find!
3) the only "issue" why I did not try to purchase this watch was the small size - a larger version I would have whisked away...
But I think even this smaller case is far too large for your wrist as you showed in the previous thread!
I think it is quite the right size for you - so just enjoy this beauty, it is near perfect!
kind regards
Erich
