(1) bezel for me personally feels ok, although not as tight as those on the ISO divers eg SKX007. But definitely not loose or light.
(2) Yes, u can order original Seiko leather or rubber strap, or aftermarket ones. Original Seiko straps can get from Thongsia, aftermarket eg isofrane can get from MWF store.
(3) AFAIK, Seiko solar movements are very robust. Just make sure that it gets some sun time daily to recharge.
All in all, its a good watch. Seiko watches are good anyway.
