It comes with a crocodile clip mount and double sided sticky tape on it. I taped it on and cut and used the plastic packaging to further protect it from the rain. As it happened, I rode in in the rain yesterday on its first outing and it survived. It also shows the temp which is nice and handy for knowing if black ice could be around.
It replaces my old watch that survived for 18 mths in the elements but the battery just ran out and Im too tight to replace the battery. This new eBay clock has standard button batteries that are easy to replace. It was so cheap I bought a spare clock.

Its easy to ready in daylight without the backlight. Havent tried it at nighttime yet. It does have a large backlight button on top for night viewing, only stays on for a few seconds.
Old watch, now dead, and no temperature reading!:
