Astron 5X Titanium Collection. With the strong, sleek lines of the Seiko Astron, the world’s first commercially available quartz watch, today’s Astron represents another leap forward, crafted for high-intensity sports in light and durable titanium, while providing the highest degree of accuracy possible in a wristwatch — effortlessly. GPS controlled for high-speed time and time zone adjustment to 39 time zones, the exceptional watch includes a daylight saving time function, perpetual day and date calendar correct to the year 2100, date window, and am/pm indicators. The unique time transfer function allows wearers to switch between the main dial time and the dual time subdial at the push of a button. To ensure smooth operation, the watch is equipped with a signal reception result indicator and power save function. The solar cell is powered by light energy, with no battery change required. Topped by a dual-curved crystal with super-clear coating, the black dial with red and silver accents includes a date calendar and LumiBrite hands and markers. With a super-hard coating for added durability, secure screwdown caseback and tri-fold push button release clasp. 20 bar, 200M Water Resistant
