# Square Dress Watches The nano universe x Seiko Selection Collection Features Compact Cases By Amy Duong | Published 2026-05-29 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/nano-universe-x-seiko References: [store.nanouniverse.jp](https://store.nanouniverse.jp/)  nano universe and Seiko have collaborated on a pair of special-edition watches released through the Seiko Selection line. Designed with a vintage-inspired square profile, the watches are housed in stainless steel cases measuring 27.9 millimeters wide, 38.2 millimeters long, and 6.4 millimeters thick. The compact proportions are paired with calf leather straps, creating a dress-watch aesthetic intended for everyday wear. Two dial options are available, offering distinct interpretations of the same streamlined design. The SSEH019 features a silver dial with black Roman numerals and matching hands, while the SSEH020 adopts a gold-tone dial with gilt detailing. Both watches are powered by Seiko’s Caliber 4N30 quartz movement, which offers accuracy of ±15 seconds per month and an estimated three-year battery life. The nano universe x Seiko Selection collection launches on June 12, 2026, with each model priced at ¥27,500 JPY.
