Small tip spring bars

Hi all, does anyone know where to get quick release spring bars with "small" tips? I'm not sure what dimension they would need to be, because I also can't seem to find general information about the sizes of any tips (just the bars themselves).

In the photo, the bar/tip on the left came with my watch (a 19mm lug-width JLC 140.8.93.S), and the one on the right is a 1.5mm quick release bar from Delugs, but the tip itself is too large to fit into the hole in the lugs of the watch (when it's fully compressed, it can just squeak by width-wise, but the tip is still not fully recessed into the hole, so it wouldn't be very secure). Any suggestions would be greatly appreciated!
