Wristwatches, in my opinion, is one of the coolest mobile gadget. It comes in all flavors and can be as simple as telling time to Temperature, Barometric Pressure, Moon Phase, Chronometer, Speed, Calculator, Phonebook and lots more...
One of the classic technology is the use of automatic movement (aka mechanical watch) that self-winds and keeps time w/o the use of battery. Such movement typically would cost a watch collector at minimum $500 to get an entry level grade. This is what makes Seiko 5 watches so fascinating.
The Seiko 5 series watches are entry level mechanical watches known for its simple elegance and reliability. The Seiko 5 watches are named as such because of its five basic functionalities: 1. Automatic, 2. Water resistant, 3. Shock resistant, 4. Date, 5. Day. The best part is that they are often a 21 or 23 jewel movement and comes within the range of $60 to $300+. The only challenge is they are hard to find within the U.S.
When I came across this watch from Amazon (actually sold by Amazon which includes free shipping a 3 year warranty), I had to give it a shout-out. This Automatic Black Ion Plated Watch #SNZD15 is considered to be a bit higher end then your typical Seiko 5 watch. It has a slightly larger 40mm face and offers a unique Black Ion finish on its metal casing and bracelet. While it isn't a true diver's watch (water depth up to 99 ft.) it does give that diver's watch style. For anyone who's interested in starting a collection in wristwatch, I would highly consider this model as it offers quite a bit of features and functionality w/o having to pay through the roof on pricing. At the asking price of $262 shipped, you'll get a high quality Japanese Automatic Movement and Seiko endurance.
