This movements connects to GPS satellites, so it automatically adjust to the local time zone, ensuring you are always in sync with the world, regardless of your location. Powering this is done by the integrated solar cells, that can charge the watch up to 6 months with a full charge. Of course the movement has a plethora of features, such as a perpetual calendar until 2100, power reserve indicator, world time (39 timeszones), dual timezones, automatic hand alignment and a power save feature.  Putting all these features in a watch is one thing, but to make it look good and comfortable is another challenge and Seiko has definitely pulled it off, by combining to notch materials and great design. To begin, the watch is made from titanium, which ensures the watch isn't too heavy (105 grams with all links) and lends the typical titanium look to the watch. The case and bracelet have a durable black coating.  The case has a modest diameter of 42.7mm and 12.2mm thickness, which both ensure a very comfortable wearing experience, despite packaging so many features under the hood. The gorgeous dial has a unique asphalt pattern and is of course protected by sapphire glass, which has a truly Super-clear coating, that makes it seem like the glass isn't there and allows you a clear view of the wonderful depth of the dial.  The SSH145J1 has a a unique blend of styles at a quality and finishing level that feels more grand than the price tag demands and is limited to just 1200 pieces worldwide.  Specifications Movement Solar Calibre Seiko Cal. 5X53 Power reserve 6 months Hand winding No Automatic No Glass Sapphire crystal Date Yes Width (without crown) 42.7mm Thickness 12.2mm Lugs 14mm Lug to lug 48mm Water resistance 100m Dial Blue Coating Super hard coating Case material Titanium Band material Titanium End links Solid Caseback Solid Limited edition Yes, 1200 pieces Country of manufacture Japan Warranty 2 years
