My first watch was purchased by my grandma in 1959 in a small Wisconsin city, $17. Exactly 32 mm, still have it through 65 years of moves and relocations around the world. Silver opaline dial with yellow gold stylized indices echoing the designs of the time. The 'Cadillac' name was icing on the cake, what kid wouldn't want a watch with that name on the dial. Decent quality with a fully jeweled and shock protected movement in a full stainless steel case with screw down back. Just pulled it out of my display cabinet and gave it a wound, still works. I consider this my 'Rosebud'.
Nice thread idea and here is my contribution :
A longines (L10) in 32mm
A Waltham A17 in 32mm
then a stretch on the specs as I believe this UG outdoorsman is closer to 33mm
And here a Tissot in 30.4mm that I bought for my wife :
and my wife got 2 more lovely longines but I have no idea where she is keeping them actually ;-)
