Seiko is a Japanese brand of watch manufactures a wide variety of watches and many of them quite interesting, as presented earlier Spring Drive Moon Phase . Presented here model costs a lot less b0 around 700 Euro.
envelope is made of stainless steel - 40mm diameter and 12mm thick. On the face of the indication of the time there is a leap year indicator, disputes date stamp, an indicator of the month and 24-hour period. Shield is covered by scratch-resistant sapphire glass. Watch
is nominally Kinetic Perpetual caliber, unfortunately, based on quartz, but with a mechanism for charging batteries rotor driven by the flow of movements of your wrist - just like in automatic watches (Kinetic) there is no need to replace batteries. The mechanism has the additional interesting feature - Auto Relay, may be discontinued for a long time (up to 4 years) then goes into sleep mode, but changing the date, and after re-moving wakes up and is immediately
ready for action. Calendar recognize leap years, and will function properly without the need to adjust the dates to the year 2100. Seiko produces quite interesting mechanisms, more information about them on the manufacturer's website (in angelskim). http://caliber.seikowatches.com/ Waterproof order of 100 meters.
