1968 Heritage Diver's GMT. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch expertise with re-creations and re-interpretations of landmark achievements. This extraordinary timepiece, re-interpreting Seiko’s landmark 1968 diver’s watch, showcases the brand’s first mechanical GMT movement in a diver’s watch, caliber 6R54. Providing a power reserve of approximately 72 hours, the longest of any Seiko mechanical watch, this 24-jewel automatic GMT movement beats at a frequency of 21,600 vibrations per hour and offers manual winding capability. The GMT hand can be set independently in one-hour increments, without interrupting the time-of-day hands, to provide a second time zone reading at a glance. Framed by a Made-in-Japan green ceramic uni-directional rotating elapsed timing bezel with knurled edge for enhanced operability, the rich green dial features a date calendar, gold GMT hand, and large LumiBrite markers and hands for enhanced legibility. Crafted of stainless steel with super-hard coating, this superbly functional timepiece includes an anti-reflective sapphire crystal, screwdown crown and caseback, new three-link, slim profile bracelet, and a tri-fold push button release clasp with secure lock and extender, and follows ISO standards for scuba diving to depths of up to 200 meters. 200m Water Resistant

    Great for dogs that are chewers
    Size: 2 Count (Pack of 1), Style: Pack of 2
    These are wonderful for our dog. The bright colors help us find them when our dog can't. The size is perfect to play fetch. Our dog will chew on it a bit and it stays together and does not fall apart. That is a big bonus because our dog is a chewer!

    It's A Whistler!
    Size: Medium (Pack of 1), Style: Pack of 1
    This Chuckit! Whistler Ball is basically a regular fetch toy that decided to become an annoying little teakettle mid-air. My dog goes absolutely nuts for it—every throw sounds like a tiny referee is shrieking "foul!" the whole way across the yard. He chases it harder than he chases the mailman, and bonus: I can actually find it in tall grass because it's screaming for help. Super bouncy, tough enough that he hasn't destroyed it yet (miracle), and now our walks sound like a low-budget horror movie.

    Great buy
    Size: 2 Count (Pack of 1), Style: Pack of 2
    Easy to track balls. My dog loves them and I like that they whistle when you throw them cause some times my dog loses track of it in the air. This helps because they can hear where it's going. Will buy again.

    My Dog's Favorite Balls
    Size: 2 Count (Pack of 1), Style: Pack of 2
    My dogs love these balls and won't play with any others. My lab has to carry the orange ball and track and retrieve the blue one. We have a system!

    Our perfect chew toy for a relentless chewer!
    Size: 2 Count (Pack of 1), Style: Pack of 2
    We have looked high and low for a ball that our Australian Shepherd couldn't destroy. Read on to find out why we are sticking with this one. We've used other Chuckit! products in the past to mixed degrees of success. We absolutely love the ring fetch toy, though the dog can destroy those rings in a couple days. We tried other "nearly indestructible" balls only to have to throw them away within a couple days because our dog had destroyed them and left small pieces around the house for the baby to find. We have been COMPLETELY satisfied by these balls. They fit with the Chuckit! stick, which is a great bonus, but the most important thing is the dog hasn't been able to get pieces torn out of them. His orange one is his "indoor toy" and he's been going to town on it for weeks without any indication of wear. We periodically inspect it and are always floored to see that it's generally in the same condition as when we gave it to him. The orange color did fade a little when he left it outside for a few days in the sun, but considering how well it works otherwise, this didn't concern us at all. The "whistling" aspect of this ball is... well, an interesting gimmick but I wouldn't buy it if that's what you're interested in. Sometimes it makes noise in flight, other times it doesn't. We don't care. He chews it until he's tired of it (which is usually hours) and it squeaks and squorks on his teeth which keeps him happy as a clam. We honestly didn't think we'd find a ball that could keep up with his chewing, but this one has been phenomenal. We cannot recommend it enough!
