I love mine..........They are VERY difficult to find even the Quartz models!!

Yep, I had both blue & silver Seaspiders back during the Yema "tulip frenzy".Several years ago they found a cache of them from when Seiko owned yema. They have high grade Seiko 4S movements in them. They sold out very fast. Most thought they were kind of ugly watches and they have been sold over many times since.
