The "Time Sonar" is a futuristic and unconventional chronograph created by Daini Seikosha in the 1970s. Inspired by submarine sonar, this model features a flyback function and a clean layout with a single 30-minute register. It also holds historical significance as the first Japanese automatic chronograph with a display case back. The 39mm case is packed with the adventurous spirit and playful freedom of its time. We recommend this unique yet functional timepiece for those seeking a distinctive vintage model.
