When I've replaced the rounded style with the can type I keep the wires as long as possible and gently bend them using a set of fine nose pliers so they sit under the crystal out of the way, if need be place a small bit of electrical tape over the wires so they don’t short on the can and stop the watch.
For example I've just done a can type crystal replacement on a Commodore module, heres a pic...

Hope this helps...
