A quintessentially accidental “limited edition” from Seiko, as its sudden discontinuation has made them very hard to find. Its dial is dark ivory with a subtle sunburst effect, and it's recessed subdials achieve a similar sunburst visual through their use of rippled, concentric circles. \u003c\/p\u003e\n\u003cp class=\"_1qeIAgB0cPwnLhDF9XSiJM\"\u003e\u003cstrong\u003eThe Hybrid. \u003c\/strong\u003eA 7D48 “Kinetic” movement. Kinetic movements originally served as a hybrid pre-cursor to the Grand Seiko’s Spring Drive movement. Just like in an automatic mechanical watch, your arm\/wrist movements spin a rotor that powers the watch. However, unlike a standard automatic movement, energy is stored in a capacitor and then passed through quartz crystal. \u003c\/p\u003e\n\u003cp class=\"_1qeIAgB0cPwnLhDF9XSiJM\"\u003e\u003cstrong\u003eThe Complication. \u003c\/strong\u003eThe main complication is a leap year Perpetual Calendar with Big Date. The main concern with an automatic perpetual calendar is the inconvenience of having to regularly reset it when it runs out of power. However, thanks to the “relay mode” you won’t have to worry about that, as your watch will enter a hibernation state if you haven't recently worn it. While hibernating the watch stops ticking, but a tiny IC stays powered and keeps track of the time and date. As soon as you pick the watch up the hands spring to life and the calendar and time set themselves accurately. It can stay in a state of hibernation for up to four years!\u003c\/p\u003e\n\u003cp class=\"_1qeIAgB0cPwnLhDF9XSiJM\"\u003e\u003cstrong\u003eThe Advantages. \u003c\/strong\u003eBeing a hybrid between mechanical and quartz has several distinct advantages. Thanks to the quartz crystal the watch is accurate to +\/- 15 seconds per month. However, unlike a quartz watch you don’t need to replace the battery every 1 or 2 years as the battery isn’t generating the power; your movement is. The recommended replacement for a Kinetic Capacitor is every 10-20 years! When fully powered, the watch has a huge 10-day power reserve.  \u003c\/p\u003e\n\u003cp class=\"_1qeIAgB0cPwnLhDF9XSiJM\"\u003e\u003cstrong\u003eThe Strap.\u003c\/strong\u003e\u003cstrong\u003e \u003c\/strong\u003eMost commonly found on aftermarket straps, this has the original leather strap and deployant buckle from Seiko.
