I didn't think anyone had taken delivery of these yet, and maybe I'd find one in a year or two when someone decided to flip. Thanks to Vincent H (cannot seem to tag him) for pointing out a couple of sellers in the WUS forums. I saw one guy was in Chicago so messaged him and immediately got a response. After some back and forth I met up with him in the evening and came home with the watch for slightly under suggested MSRP. I can say with confidence I'm pretty sure this may be the only one in the United States right now. This one came form an AD in Macau with a stamped warranty card.
My only other experience with Seiko silicon straps is on the SKX line, and the OEM one this came with is worlds better. Much softer and more flexible, and with a sturdier black metal keeper. I had intended a change but I'm going to leave this on as I've got the full range of straps now on my Seiko divers - silicon, bracelet, Nato and leather.
