Prospex U.S. Special Edition. 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 excellence, leading the way with new advances, while re-creating and re-interpreting landmark achievements. Inspired by Seiko’s 1965 landmark first diver’s watch, this exceptional Special Edition is one of a trio celebrating some of the most demanding diving locations in America and those who dare to explore them. Patterned to evoke the icy surface of the perilous, yet beautiful, Alaska Moulins, the gradated light blue-gray dial features a date calendar and bold LumiBrite hands and markers, and is framed by a dark gray uni-directional rotating elapsed timing bezel. The curved sapphire crystal with anti-reflective coating on the inner surface provides enhanced legibility. Crafted of stainless steel with scratch resistant super-hard coating, this rugged and stylish timepiece also includes a screwdown crown and caseback, and a tri-fold push button release clasp with secure lock and extender. Following ISO standards for scuba diving to depths of up to 200 meters, this exceptional watch offers manual winding capability and includes a 24-jewel automatic movement with a frequency of 21,600 vibrations per hour and a power reserve of approximately 70 hours. 200m Water Resistant

    Large is a little big for Bostons
    Color: Dogwood (Brown), Size: Large (Pack of 1)
    Seems to be durable for 2 VERY agressive chewer Boston Terriers. Cricket and Alice are shockingly good at chewing - grateful they pick to do so with thier toys. Trial vs other name brand competitor. PetStages' is a little larger so harder to bite on fir small dogs, but seems to be equally durable. While PetStages proudly states it has real wood fiber and scent (whoch I thought would win)... they prefered the other. Both dogs love to chew on real sticks. But, when the bossy one indicated she was taking over the stick the other dog had, they exchanged, and kept chewing, over and over, back and forth. I mean to say, whatever the prefered stick was at first didnt seem to matter later. These super hard chew toys do make me nervous. One dog broke a tooth last summer on a different brand toy, a very expensive extraction bill, and poor pup's terrible discomfort... but the other did not and has amazing white teeth, all around.... so.

    The best chew ever for a strong chewer
    Color: Dogwood (Brown), Size: Large (Pack of 1)
    We have a 77lb goldendoodle who loves these. We’re lucky because he doesn’t chew on anything other than his toys, but when he starts on this…he really goes at it. It’s healthy, (not synthetic), doesn’t break apart, (no pieces to worry about him swallowing), it just perfect for him. The noise may get on your nerves but it’s a small price to pay to keep him from chewing on your furniture, shoes, or anything else a mischievous dog can find.

    Little pieces break off
    Color: Dogwood (Brown), Size: Large (Pack of 1)
    My dog is obsessed with this. It does last a long time even given her strong chewing capabilities. I wish it was a little bigger. The main reason I rated it so low is when my dog is chewing on this it breaks off a little plastic peice and sometimes it hits the back of her throat making her cough so you have to supervise with this.

    Great for aggressive chewers
    Color: Dogwood (Brown), Size: Large (Pack of 1)
    My dog is an aggressive chewer so they are great for her. I would love to have one a bit thinner so it could fit in a holder so it is easier for her to hold while eating. This keeps her busy and is long lasting. I have purchased these multiple times.
