Seiko El-370 Vintage Electro-mechanical Wristwatch Oh Serviced Japanese 1970s

This is a 1970 "SEIKO ELECTRONIC EL-370" with its instruction manual and has been overhauled.

It is a valuable hybrid structure from a brief period before quartz watches became widespread, known as the "electromagnetic balance wheel" type, where the balance wheel of a mechanical watch is powered by a battery.

The futuristic, streamlined tonneau (barrel-shaped) case symbolizes the space-age design of its time.

The dial shows a patina typical of vintage watches, having changed to an ivory tint, which enhances the "withered" antique charm that cannot be replicated by modern products.

Combined with the original mesh belt, it exudes a unique vintage elegance.

It comes with its original tag and instruction manual, and is in superb condition, having just been overhauled in October 2024.
