Looks like one that works on less than 5mm crowns (which is what I'd need) is only available on there from Bergeron... so it's $37! Hmm... they do make good stuff...I have one vintage watch with a very small and somewhat hard to turn crown when setting the date (my Omega). And it has no quick set date (of the crown, or hands back-and-forth type), so you have to wind the hands around and around and around. I usually keep it on a winder because of this, but this tool could actually be very helpful. Thanks!
