The Mercury watch displays time in a simple and unique way without any alphanumeric characters or traditional watch hands. Instead, the tip of inner swirl represents the current hour, while the outer swirl displays the minutes, with a continuous gradient movement showing the passage through time. Built with quality in mind, the Mercury watch is constructed using 316L stainless steel casing, case-back and fully adjustable strap. The metal straps of watch models ZIIIRO Mercury, Celeste and Saturn are made to fit a wrist size of about 13.00 cm 21.00 cm. The size can be easily changed in seconds using a flat screwdriver. Water Resistant 3 ATM or 30 m. Suitable for everyday use. Splash/rain resistant. NOT suitable for showering, bathing, swimming, snorkeling, water related work and fishing. If you don't take your watch for a swim, you should be fine.
