What time is it? Watches and horology

There is a perception that the Japanese models are superior due to the single origin of manufacturing and assembly. K models are built with parts made in various SE Asian countries with assembly in a number of places, mostly Singapore.

I have always bought the J models when possible.

However, from exploring the Seiko forums and other watch forums this seems to be largely urban myth as the watches are made with the same parts and by the same equipment regardless of location.
