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

    Love it but it stains
    Color: Haze Blue, Size: 2 Pack Standard(20"X 26")
    I love these but had to knock some stars down for a single reason. They are soft, the material is somehow both substantial and airy at the same time, and a smooth, silky (not satin), cozy texture. The color was exactly as pictured. The envelope style works great to keep my pillows covered. The fabric lays perfectly. I love sleeping on this pillow case. Took two stars off because every single atom of oil on my face stained it immediately and won't come out in the wash. Its not subtle. You can see anywhere my face has been, forever. I don't have some incredibly oily face or hair, I've never had this happen to another pillow case in my life.

    Silky and Soothing
    Color: Cream, Size: 2 Pack Queen(20"X 30")
    I thought I was getting 1 of the queen sized but I got 2. I got these for my Pomeranian's fuzzy pillow. He's always hot and these are very cooling and very good quality. He loves them and are very comfortable for him. They totally transformed his shaggy old pillow. I used the larger body pillow covers to replace the covers I had. They matched my bedspread perfectly. I use 2 body pillows along the exterior wall in my bedroom where there is cold coming through the floor in the winter. I'm sure I will enjoy them in the summer when it's hot too!
