I use this ... Dakota hanging clip-on sport watch. What's essential when selecting a clip-on watch is that the clip that holds it in place is firmly attached to the watch (so it won't fall off into the snow), and that the watch hangs with its face upside down (so you can glance down onto your jacket where it's clipped and read it without touching it). Nothing fancy at all, easy to find online, inexpensive, and it shows me the time with no struggle to find it under a sleeve. That's all I need.
