In the 1960s or 70s, Seiko made a really neat Beer/Soda Coozie that was a promotional piece which says, "Someday all watches will be made this way." I was able to score one of these and, after showing it off to the Seiko community, it was clear that a lot of people wanted to get one. So, I had some made.
After polling my Instagram followers (@uncleseiko) on whether they preferred thick or thin foam, it was about a 50/50. So, what the heck, I made them both. The thick is more of the classic vintage style, but the thin is easier to stick in your pocket and take with you to the beach or summer party. You decide which works best for you. We are all about choices here.
