r/watchexchange, I'm selling a rare automatic flyback chronograph Seiko 7015-6010 "Time-Sonar" from around 1974-1976. I cannot get a solid answer on these. I believe this to be an original bracelet, but cannot confirm unfortunately. I have seen several threads with multiple bracelets as well as chronosweep colors and day/date wheel colors. The top of the case still maintains a great bead blast finish. **CASE**: 38mm x 43mm stainless steel case, with correct tinted see-thru caseback. **CRYSTAL**: Hardlex crystal, has light scratching with major scratch over the day/date. The watch has been running well when fully wound. While I don't have solid information about its servicing history, it functions smoothly and keeps time accurately. The pushers work flawlessly, however, I try to keep the sweep moving at all times as these share a lot of the same structure as 6139s. One thing to note is that the day wheel hits a bit low in the window. The alternate language is Arabic. For more detailed specifications and the fascinating story behind this timepiece, I recommend reading the great Fratello article on the Seiko 7015-6010 "Time Sonar" Chronograph.
