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

    Kids?
    Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
    I didn’t realize these were kids socks, until after I got them, but the fit is amazing and they stay put, without coming off my heels. I wear an 8.5-9 in women’s shoes.

    Favorite Socks Ever
    Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted
    I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!

    Great ankle socks that stay put at a great price!!
    Size: 6-9, Color: Assorted
    These are great! I have been looking for a low profile ankle sock that is thinner but doesn’t ride down. (Picky, right?) I try to walk 5-7 miles on my days off. So it’s very important for me to not have to stop every couple of hundred yards, bend down, fix socks, then continue on my way while grumbling about NOT GREAT socks. These are not those socks. They really do stay put!!! And enough cushion to be comfortable also. So definitely a repeat!!

    Great quality, no holes or fading!
    Size: Medium, Color: Black/Assorted
    I purchased these socks a couple years ago and love them so much that I just recently purchased them again! They fit perfectly, don't make my feet sweaty, and hit the ankle at the right spot. The material is so good that over years they have not faded and even though I wear the same few pairs every day, they have no signs of thinning or holes! These are the ONLY socks that I buy. I have the black ones as well as the multi-colored ones. I will never buy another brand or style again!
