The Zenith Men's Defy Xtreme Tourbillon Titanium Chronograph Watch or


Z.M.D.X.T.B.T.C.M. as I like to call it, is by far the most awesome watch. Chuck Norris riding into the Super Bowl on the back of Godzilla and round house kicking the crowd is no where near as awesome as this priceless poon magnet. When I was just moments from sending my $100k to some needy neo-hippie help group, I stumbled onto this gem. It was like the heavens opened and Jesus himself appeared with this same watch on. I mean how can you not follow Jesus when he's rocking a watch of this caliber. So I asked "What would Jesus do?" Jesus pimp smacked me and said "Forget those hippies, buy the watch!" I was like "HECK YEAH." I busted out my Discover card and bought this rocking piece of art. I mean its art but its also practical too. Like when I take my summer trips to the Marianas Trench, I have no more worries that I am going to miss Tea Time back on the yacht, because water ruined my watch again. It can withstand the immense pressures of the deep due to the wicked awesome titanium. Deep seas, cant beat this. Bullets cant beat this. Heck, I can deflect cruise missiles and the apocalypse. With a watch like this you don't need to tell time, you tell people what time it is.

Discussion
This watch looks great. Unlike other self-winding or kinetic watches, this one is compact. In the best tradition of Japanese product development they thought hard on how this watch should function and say about the wearer. The hands are easy to reading, even for those of use with failing eyesight. The second sweep hand has a read tip allowing easy setting of the time.

Unlike some Japanese product, they provided a short, simple instruction on winding the watch. Here, I am comparing them to Citizen's ecco-drive watch, which I also own. Just gently work your arm back and forth for three minutes and the self-wind watch will charge; or, you could wear it for a day.

Okay, now for the negatives. First, this is not your quartz watch. The original self-winding mechanism was invented, according to Wikipedia, by a Swiss watchmaker in 1770. Since then it has gone through several improvements but is not as accurate as the quartz mechanism popularized starting in the 1970's. Sieko warns that this watch could be off by as much as 10 seconds a day. One days use indicates that my watch runs about 10 seconds fast.

The great watchmaker Harrison, who invented the first chronometer accurate enough to track longitude, said that consistency is more important than accuracy. (A poor copy of one of Harrison's chronometers was carried by Captain Cook on his circumnavigation of the globe. He had nothing but good things to say about it.) I have another self-winding watch, an Armitron, which runs consistently 15 seconds fast on days that I wear it.

From my measurements of quartz watches, their accuracy, while dazzling when compared to old hand-wound watches, are less accurate than my old German pendulum clock. So I am told, the longer the arm, the more stable the swing and the more accurate the timepiece. I compare everything to atomic time. And, because the quartz mechanism is battery-driven, it seems to suffer from inconsistency. I carefully measured my collection of six quartz watches over a 2 year period. While the battery was new, the error was consistent. As the battery burned out, the error became difficult to predict. Sometimes a positive error (adding time) would become a negative error (losing time) as the battery died. This dying period was also hard to predict.

The accuracy of the quartz mechanism is not as good as my pendulum clock. They all lost or gained approximately 2-3 seconds, on average, per month.

Based on a week of measurements with the Armitron, I would say that it is shockingly inaccurate but consistently so. Assuming that the Sieko error continues to be consistently 10 seconds fast this will mean that I will have to reset it every week. This is a small price to pay for an otherwise beautifully crafted and honestly-priced handiwork.

Setting time
The date and day are fairly easy. I suggest turning the watch arms until the click past a day so you won't be twelve hours off.

Setting the time is another matter. What works best is to set the hour and minute hands, then gently hold the second hand. It should pulse a little as it tries to force itself forward. Once the seconds are accurate, release and the second hand should be accurate. It takes a little practice at first and don't set the time until you pump the watch 3 minutes to charge the spring.

Seiko Men's SKA347 Kinetic Silver-Tone Watch
It was at the 1986 Basel Fair that SEIKO unveiled its first Kinetic prototype. Introduced under the trial name of 'AGM', it was the first watch in the world to convert kinetic movement into electrical energy. It was the first step in a development that, 20 years later, has made Kinetic synonymous with environmental friendliness, high performance and long-lasting convenience to a generation of users worldwide. From the launch in 1988 of the first commercially available watch (then under the new name AGS) until today, over eight million Kinetic watches have been sold (as of 2007).





The Seiko SNDC47 is a very nice/sporty watch that is also classy. All the functions work as described and I really enjoy wearing the watch. The only problem with the watch is that it can be difficult to read in low light settings. The silver hour/minute hands
