The Freestyle FX Trainer Vibrating 100-Lap Digital Sports Watch is designed with durability, comfort, and functionality in mind. It's equally at home on your wrist whether you're resting on a lounge chair during a hard-earned vacation, inside wiping your brow as sweat drips down your back in spinning class, out riding waves as they try to toss you off your surfboard, slicing the blue-green ocean with precise strokes as you swim towards shore, jogging through a favorite sylvan park as you listen to your tunes, or squeezing out that last rep as you pump iron. Wearing the FX Trainer Watch is like a promise to yourself that you will keep moving and stay active. Just buckling the FX Trainer's ventilated, silicone, sports strap prepares you to do your personal best. This watch is all about performance. The 100-lap memory FX Trainer welcomes any and all workout challenges. Featuring a dated training log, five interval timers, and optional vibration alerts that allow for non-stop training and for you to really crank your music. Water-resistant down to 330 feet (100 meters), this is just the watch for ocean lovers. In fact, you can even press the buttons under water without the watch flooding thanks to the Hydro Pusher water-resistant buttons. Great for anyone, the Freestyle FX Trainer Vibrating Digital Sports Watch is just the right size with a 40mm (1.58 in.) case— not too big or too small.
