Not sure how old these actually are, but I inherited them from my Nana who passed away in the early 1990s and she'd owned and worn these for decades - I would guess these are from the 50s/60s. Silver metal expandable bands on all 3, all fit a smaller-sized wrist but each watch's size differs slightly. I used to wear all 3 at the same time and it looked funky and cool. The smallest one still works and has a winding mechanism; the other two are likely battery operated but I'm not 100 percent sure. The larger watch has a blue bezel. Selling as a set.
