Watches

A little iffy on the cost, for what you get - which is basically enough parts for a single watch. For those non-sale prices, if you already know your way around the Miyota 82xx or even some of the cheaper Chinese movements, you can buy parts for multiple watches plus a serviceable tool kit (though perhaps not one from Bergeon).

This is true for all of those "assemble your watch yourself" kit sites. IMO you're better off buying the parts yourself, perhaps from a modding site (the one I linked is for Seiko and the listed prices are in Singaporean dollars, but you get the idea).
