For sale is a vintage Seiko Silver Wave digital quartz watch—an incredibly cool piece of 1980s/90s design that merges functionality with bold aesthetics. This model features a distinctive angular case with pushers on both sides, embodying the experimental digital era Seiko was known for. The brushed stainless steel bracelet and sharp, geometric lines give it a retro-futuristic vibe that still feels relevant today. The dial includes full calendar functionality (day/date), alarm, stopwatch, 12/24 hour format, backlight, and even a solar battery panel—remarkably forward-thinking for its time. You’ll notice the “Silver Wave” branding on the top of the case, a hallmark of Seiko’s water-resistant digital line. This example is in mint vintage condition. The digital display is crisp and legible, the buttons are responsive, and the timekeeping is accurate. (Please refer to the photos for condition details.) These Silver Wave digitals aren’t easy to come by, especially in this kind of clean, original condition. A must-have for fans of Seiko’s golden age of innovation or anyone seeking a conversation-starting vintage piece. $240 USD - tracked international delivery from Singapore
