J. Springs is a Seiko sub brand. The name means "Japan Springs" (ask seiko what they were trying to convey with that one). It was introduced in 2001 and is actually owned by Seiko Instruments (the former Daini Seikosha). All of their movements are entry level, unmodified Seiko Instruments quartz and automatic movements (such as the intro level 7s). Their watches are all entry level models with styling being the main focus. They have a number of diver styled watches, but no true divers that I know of. The brand comes in somewhere between Pulsar and Lorus (probably closer to the former) in the Seiko hierarchy. They are marketed globally and no, I have no clue on how they differentiate from other brands (especially pulsar). There sure seems to be a lot of overlap though.ANY ONE KNOW ABOUT J-SPRING WATCHES.
