I can throw up a few of my wife's favorites. Her absolute favorite is this 1932 Hamilton Greenwich (stolen from my collection...of course).
This vintage LeCoultre Caprice is among her favorites.
This Rado Integral Jubilee was her first "nice" watch.
She has her own example of the 1962 Hamilton Gary on short leather strap that she wears often. Here's is mine on it's original bracelet for reference.
She has another 50 or 60 watches to choose from but these are the usual suspects.
