I haven't worn a watch in a while and I kinda miss it. I like the looks of the Seiko 5. The only problem is that I don't want a watch that needs to be removed to shower, and apparently the 30m rating on the 5 is not up to the challenge. But wait, some places list Seiko 5s with 100m waterproofing with no difference in model number. So I thought I would go to Seiko's website to get a definitive answer, but to my surprise the SNK807 does not exist there. Would someone please explain what is going? Thanks!
