SEIKO ELNIX 0703-8030. The gradient green dial is cool. It's an electromagnetic balance wheel type, which is no longer in production. The strap is aftermarket, but I think it has a good feel. The battery is dead. The battery was dead when I got it, and I've been meaning to get it replaced, but it's still dead. I've decided to sell it because my collection has grown and I don't think I'll use it in the future. This product is almost 50 years old since its manufacture. Considering the impact during transportation, I'm selling it as junk with no guarantee of operation. It's an endangered species now, the electromagnetic balance wheel type. For those who like it, please consider it. CITIZEN COSMOTRON Electromagnetic balance wheel SEIKO ELNIX EL-330 EL-370 Antique Quartz Mechanical
