I usually keep a watch for a year or so then replace it because it is missing one or two key features. I've been wearing the SGW-100 for about a year and I decided to replace it. I've tried the SPF40 sea pathfinder, various cheaply built Casio Sport watches, and now I have the SGW-200 and SGW-300 incoming for testing. Not hopeful.
The SGW-100 is low price but high-quality, something you don't always see with Casios in the $20-50 range.
However, I'm starting to think the search is a waste of time. The SGW-100 is a great watch for me. It's got almost everything. However, here's what's missing:
-- 24hr CDT (not a huge deal, 60 mins works for me)
-- regular EL backlight (I find the reverse a bit annoying)
-- more of a blacked out look. Over time the sliver bezel bothers me a bit.
Sunrise/sunset is a big one for me. I posted awhile back asking on this feature and of course the PAG-240 came up as did the hunting/fishing watches. Unfortunately I just don't like the PAG40 design. The hunting/fishing timers have camo straps I don't like so much and the watches are a bit small.
So, you can see I'm at the horns of a dilemma. I'm very close to giving up the search for awhile, which isn't necessarily a bad thing. It just means the SGW-100 is as close as I can get to the best watch for me.
