Up for sale is the Seiko Speedmaster 7A28-7040 (The World’s First Analog Quartz Chronograph) in excellent condition Images: https://imgur.com/a/B28JnlC Video: https://imgur.com/a/7VBBRDP Timestamp: https://imgur.com/a/vpRfO5U This Seiko 7A28-7040 is an early example of the world’s first analog quartz chronograph, produced in December 1982—just before its official release in 1983. It has a 40mm stainless steel case (excluding the crown), a 45mm lug-to-lug distance, and a slim 10mm thickness, making it an easy and comfortable wear, especially for wrists 15.5 cm and up. While originally rated for 30m water resistance, it’s best treated as splash-resistant given its vintage age. One of the standout design features is the black tachymeter bezel, which contrasts against the steel case and gives it a distinctive, motorsport-inspired look. The dial is clean and well-preserved, with no signs of aging, and the tri-compax chronograph layout keeps everything looking balanced and functional. Unlike most quartz chronographs, the 7A28 movement offers a mechanical feel, with crisp pusher action and smooth, precise timekeeping. The watch is all-original and in great shape for its age, with only a few minor scratches on the case. The battery has been replaced, so it’s keeping excellent time. The original bracelet fits up to 18.5 cm and remains in solid condition. Standard Seiko box will be provided upon purchase. Price: $450 + $35 flat shipping (via FeDex/DHL). Payment via PayPal F&F or G&S (+4.6% fee paid by the buyer). Not accepting trades. Feel free to message me with any questions or if you’re interested. Have a great day!
