I just picked up an old H. Stern sapphire watch at an estate sale. Only trouble is the band that connects to the watch through a single t-bar lug is broken. I didn't look that closely at the watch until I got home, and had figured it would be as easy as getting another t bar screw lug and replacing it... Well when I started fiddling with the watch I realized that while the band looks like it has a simple t bar screw holding the band on it doesn't seem to work that way. I tried to unscrew the good side of the band from the watch so I could get a measurement of the screw I would need to fix the broken side and turning the screw doesn't seem to do anything. Nothing gets looser, I look at the end opposite the screw that I'm turning to make sure I'm not turning the whole thing and that side isn't turning when I unscrew the other side... but nothing seems to be happening.
Does anyone have any experience with this type of watch? I don't want to mess things up royally trying to fix it.
