Seiko 5 dropped and stopped working

[otherman]

I dropped it on a hard floor, and it's stopped. The second hand starts up if I shake the watch gently (as you might if it hasn't been used for a while and needs a wind) but stops if I stop moving it.
Any hope?

What sort of age of Seiko 5 is it? Parts availability varies quite a lot between the newer ones and the old 80s / 90s versions.

I bought it in 2004. Are the easier fixes things I can do myself? I'm thinking since it was £50, any sort of repair bill will soon overtake its value.
