Why Collectors Love It:
The Time Sonar line was Seiko’s answer to 70s futurism. The radial dial plays with light, and the integrated bracelet gives it a clean, almost sculpture-like profile. It’s lightweight, comfortable, and wears larger than its size thanks to the case shape.Specifications:Brand: Seiko 5 SportsModel: 6106-8470 Time SonarEra: Early 1970sCase Size: 38mmLug Width: Integrated braceletJewels: 21Condition: Serviced, fully functionalAuthenticity guaranteed.
