Prospex Speedtimer Mechanical Chronograph. Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Driven by a heritage of iconic design, Prospex continues to keep going forward with excellence in precision timekeeping, crafted for the modern world. Based on Seiko’s Speedtimer chronographs of the early 1970’s, this powerful creation offers superior timekeeping combined with sporty elegance and wearing comfort. Providing chronograph measurement of up to 12 hours of elapsed time in 1/8-second increments, the proprietary caliber 8R48 34-jewel automatic movement beats at a frequency of 28,800 vibrations per hour, with a power reserve of approximately 45 hours and manual winding capability. The movement incorporates a column wheel and vertical clutch mechanism allowing for smooth, stutter-free movement of the chronograph hand while providing long-term efficiency, reducing wear and tear, and maintaining the power reserve during chronograph operation. For reliable timing, the three-pointed hammer system ensures that all hands return to zero instantly and in perfect synchronization when the re-set pusher is pressed. The black dial, framed by a tachymeter scale for an authentic look, displays the word “Speedtimer," honoring Seiko’s sports timing legacy, and features subdials with a contrasting finish, a date calendar, and LumiBrite hands and markers for superio r visibility in low-light conditions. Crafted of stainless steel with super-hard coating for exceptional scratch resistance, this extraordinary watch is fitted with a sleek multi-row bracelet for a note of tailored luxury and includes a dual curved sapphire crystal, a secure screwdown caseback, and a tri-fold push button release clasp. 10 bar, 100M Water Resistant

    Great product! Durable, chewable, awesomeness!
    Color: Grilled color, Color: Grilled color
    Very well made and durable. My dog hasn't left them alone since i opened them. Hes been at it for about 45 minutes straight now! Lol. He's an avid chewer. He will chew thru and fabric or cloth toys in less then a day. But these are what he really likes because they take time to chew apart. The shapes, are great, because one he props up with his paws and chews and it seems like it's easy to grip for him. Thru are hard so if you have hard floors it can get a bit noisy when he drops them. Over all this is a great product. Safe, chewable, long lasting, fun shape looks real to him (i think lol), Me and my dog Lucky are both happy with his new toys!

    Amazingly great product!
    Color: Grilled color
    I’m not just saying this, ok, this is not hyperbole: this is THE best nylon bone for chewing that I have ever purchased. And you get TWO of them for relatively less expensive than most chew toys give you one! I have 2 golden retrievers, and if you know goldens, you know that they are some of the most relentless and powerful chewers around. So I can’t give them almost any toy other than rubber stuff or it will be destroyed in a period of time that doesn’t make it worth it. One of them even figured out how to destroy a supposedly indestructible toy made out of kevlar! She was able to get into it through the seam, which is not kevlar ha ha. Anyway, I digress; I never even considered nylon chews because they suck! Usually. Usually my dogs in the past have lost interest with them in less than a day. I took a chance on these mainly because of the novel shapes, the fact that they give you two, and the low price. Both my goldens LOVE these! Not just for one day, but going on weeks now! I don’t know if it’s the flavor or what, but I will see them gnawing on one of them at some point every day. And they CAN’T destroy them (I knew nylon was good for that, but it was the “who cares” attitude of my previous dogs toward nylon that kept me away). Both the “ribs” and “steak” (quite clever) are a bit worn on the edges now, but they look like they will be around for years. You can’t go wrong with this product (unless for some reason your dog does not like the flavor, but the flavor seems to be what draws my dogs to them). I highly recommend this (these) as the most cost-effective chew toy I’ve ever purchased.

    Great for larger dogs
    Color: Grilled color
    I think they were heavy duty and durable, but they were too heavy for my dog. The seller was excellent though!
