I posted the black military style Seiko Kinetic (SMY143P) in my previous blog entry. The 5M83 kinetic movement has a power reserve of approximately six months when fully charged. I believe you can consider it a grab and go watch since it will most likely have enough power reserve to last through the unused period.
This watch works well with different straps. It comes with a two-piece nylon strap but will also look good on rubber/silicon, leather and nato straps.
Here are some picture of the green dial variant – SMY141P.
