looking for a timex quartz mechanism

i want to fix this. no idea of the year. no model number anywhere. the mechanism has a cracked plastic wheel in its depths. the movement is marked 6 jewels, made in korea, 249-460020-10. the back is marked "v cell". i've no experience with quartz movements. is there anyone who can tell me about the availability of this one? is a particular one usually difficult to find? some easier than others? did timex use lots of different quartz movement models? any advice? i'd buy or trade. thanks, tim
