Why does titanium feel so good on your skin?
There are many articles in watch magazines and forums--or is it fora?--touting titanium as the metal of choice for wearing comfort. In addition to its light weight and easy-care finish, titanium feels pleasant to the touch, never uncomfortably hot or cold like more popular metals, such as stainless steel and gold.
1. DISPELLING THE MYTHS
Let us first dispel the popular myths. It is not the "temperature" of the metal that causes the different feels. Another popular myth is that titanium keeps your body temperature better than other metals because it has a high "heat transfer efficiency." This explanation is also wrong.
2. THE IMPORTANCE OF SUDDEN TEMPERATURE CHANGES
Indoors, watches are essentially at THE SAME TEMPERATURE--the room temperature. But when you put a watch on your wrist, different metals feel very different on your skin: titanium feel neutral, comfortable; steel and gold cold. Likewise, wood furniture or the carpet feels nice, while the sink or marble floor feels cold. Here is why.
The thermal receptors of our skin respond to steady levels of temperature. But they respond more sharply to sudden temperature changes before fading back, in less than a minute or so, to a control level. It is this stimulated response that dictates how a metal feel on our skin. As we put a watch on our wrist, it quickly draws heat from the skin causing the skin temperature to drop: the metal feels cold.
In a nutshell, it is the sudden temperature change, not the steady temperature, that dictates the thermal comfort.
3. HEAT TRANSFER: WHEN EFFICIENCY IS UNDESIRABLE
ALL metals conduct heat efficiently and reach your skin temperature soon after contact. But stainless steel, aluminum, and gold conduct heat 2, 11, and 15 times more rapidly than titanium, respectively. So, unlike titanium, these metals draws heat very quickly from your skin, causing its temperature to suddenly drop, thus creating the cold feel. Heat transfer efficiency causes thermal discomfort.
Under a bright sunlight or in a sauna, the reverse process takes place. Stainless-steel, aluminum, or gold are such effective heat conductors that they absorb heat very quickly from the surroundings. You feel heat, or even pain as these metals become suddenly hotter than the skin. On the other hand, being a less efficient heat conductor, titanium heats up more gradually thus causing only a mild response from your skin. Also, given more time to dissipate the heat, the skin--and the watch movement--is less likely to overheat or burn.
The most vivid illustration of heat conduction efficiency I recall was given by an engineering professor at the University of Fairbanks, Alaska, where good understanding of heat transfer is essential to your health. He asked the following question: when it is-30°F outside, a common occurrence in Fairbanks, Alaska, and you have to go to the outhouse, what would you prefer to use? A Styrofoam seat or analuminum seat? All his students knew the right answer!
Thus, the most comfortable watch metal is the poorest heat conductor--titanium.

Oris 674-7633-4764LS Aviation BC4 Chronograph Automatic Mens Watch
A watch so classic and chic, it’s addicting. This deal of the day is $1349 (74% off the $3775 retail price). Sale ends at midnight tonight (EST).
Um. Okay. I guess the addiction started early on when I was a teenager. I saw my dad with it, even though he tried to hide it, I still saw. Then, when I was old enough and saved up enough money, I bought my first one.
Of what? What did you start with?
Oris.
Ooh! I’ve never heard of that one before. Must be a new thing kids are getting into these days. Tell us about it.
Well, the Oris in particular was a classic Black DLC tone Stainless Steel watch, much like the one my dad wore.
Wait, Oris is a watch? You’re a watch addict?
I still remember the first time I put this baby around my wrist. It was intoxicating. The comforting cool of the stainless steel, the way the sun shimmered off of the black dial and scratch resistant sapphire crystal, the precise automatic movement, and the JomaDeals 2-year warranty. It was the perfect, classic watch. I never wanted to take it off. In fact, it’s water resistant up to 330ft, so I could even shower with it.
And is that where the problems started for you?
Problems? I never really had any problems with it. My girlfriend loves it, all my friends ask me where I got it, my boss says I look sharp, and most of all, I have the approval of my father, which was really the reason I got into this stuff in the first place.
So why are you here then?
I dunno. I’m addicted. This is an addiction help group. It’s Saturday, and I was bored.
That’s it. Meeting adjourned. Pete, we’ll have to address your addiction to Nickelodeon Boy Bands later. No whining. The Jonas Brothers will still be around next week.

Conquest watches deal - Swiss Military Conquest Mens Watch 06-4035-04-001
New Year’s Resolution #82: Conquer something. Now this may surprise some of you, but there are a few people who’s New Year’s resolutions are less than pure. Napoleon, Attila the Hun, Caesar, Hitler, Ashton Kutcher, all made a New Year’s Resolution to conquer something. And they all succeeded (Ashton settled for Twitter). There were also a few who didn’t who have been lost in the annals (teehee…annals) of history, like Dave Bonaparte, Bobby the Hun, and Little Caesar (he got a successful pizza chain out of it, though). So what’s the difference between success and failure? I’d like to think it’s today’s deal of the day, the Swiss Military Conquest Men’s watch. This timepiece was one of the major hits of 2009. Its simple, retro look goes great with jeans and a t-shirt. It’s an everyday watch with a comfortable brown leather strap that will make you look good when you go a’ conquering. And as part of our “Best Deals of 2009” series, we’re giving it a higher discount than before, dropping it to about $39 bucks when before it went for$48. It’s one of the few times in life where it pays to procrastinate. So buy today’s deal of the day, and get all the confidence you need to conquer your own little sphere (but try to conquer something that doesn’t result in the death of millions, like facebook or something).Jomadeals.com does not ship outside the USA and its territories.

ABOUT BRAND
Hans Noll came to Biel in 1961, following a broad-based commercial career, and took over the European sales management responsibility for a mid-sized watch factory. In 1963, following a management changeover, he left this company to set up his own business with his wife. As sufficient capital was not available to buy a brand for himself, he used his imagination and blended the founder's name Hans Noll with the word Watch, giving birth to the brand name Hanowa. Already after only a few years, watches were being produced under own management, giving Hanowa right from the outset a reputation for fantasy watches (ring watches, pendant watches, clip watches, watch sets and much more). For the past 15 years, the company has adapted itself to the changing market trend and converted its production over to sports watches. Thus the "Swiss Military" brand was born. Soon afterwards sister brand "Swiss-Eagle" followed, appealing to the same target audience but offering special, exclusive models.

JomaDeals: Fossil BQ9365 Watch
http://www.JomaDeals.com Deal of the Day
Fossil Multifunction Blue Dial Watch BQ9365
Mon, August 10, 2009
Chic women’s watch with a style only Fossil can deliver. Yours today for only $49 (61% off the retail price). Sale ends at midnight tonight (EST).
Happy Monday everyone! I know Mondays are usually about as happy and chipper as a stapler to the head, so allow me to brighten your day by offering you a chance to do a little shopping in a minimized window while your cubicle-buddy is looking the other way.
Today's deal? A gen-u-ine Fossil Ladies Watch. What can I say? Fossil watches are truly one of a kind. It calls back to the by-gone era when people dressed up to go out to dinner, danced the Waltz with live bands, and actually enjoyed real human interaction (thanks for ruining all of that, TV and internet, of course without the internet we wouldn’t even be here, so maybe I should be careful what I criticize). Fossil's taken that era, while at the same time making it modern and unique. It's modern vintage in its truest form. And with JomaDeals’ satisfaction guarantee, if this deal fails to officially brighten your day, we'll exchange it for one that will (along with a box of donuts for "Pastry Fridays" next week, it's been a while since it was last our turn).
