Seiko automatic watches
Seiko automatic watches are equipped with robust and durable mechanical movements that are self-winding and hacking with approximately -15~+40 seconds accuracy per day depending on the calibre. The movement are exquisitely manufactured in-house at Seiko Instruments, Inc. Higher and newer mechanical movements use Spron 510, a mainspring (made of high-elastic materials) that generates power reserve for more than 45 hours.
Over the years, Seiko automatic watches have proven its reliability alongside its reasonable price. And with recent developments and innovations some even consider it at par with more expensive movements available in the market.
