I bought an aluminum sport Series 0 off ebay the December AW came out. I got an excellent deal, but I really liked the look of the stainless and wanted one of those. So when the next upgrades came up a few months later, I bought at SS with link bracelet at BB for around $230 or so. (It was a ridiculous price.) I've used these two Series Os through now. My Sport is coming apart--possibly the swollen battery effect. I mostly use that for sleep. My SS seems to be slowing down, and so I was thinking of upgrading. I want to stick with SS, as I like the look. Based on the rumors and such, would be best to upgrade now or to wait for the latest watch this fall? Thanks in advance for your thoughts and opinions.
