I love all watches, have about 50 of quartz and mechanical.
Seiko mechanicals are well known and respected, (Orange Monster, etc).
Many countries do not have wide availability of the various batteries
used in quartz watches, so mechanicals are handy.
You would really enjoy an article on ThePurist.com, that is an
in-depth review of the 7S26 movement. This site deals with High End
watches, but "8ohms", a very good watchmaker, reviews this movement
and Loves it !. It is simple, efficient, and sturdy. This review is found
in the reviews "In Depth" section.
It's a good read, and,actually a great, friendly, site.
I recently posted a topic as Larry Larkin, in the "watch rap" forum
entitled "out of the closet", in which I asked who owned a G-shock
and would admit it !. Got some great responses.
Check Them out, LL
