This is simply the best, most functional watch I own. I own a couple of "jewelry" type watches, but for the most part, this is the watch I wear day-in and day-out. I have taken the watch diving, into sub-zero temps, alpine environments, and extreme heat. It gets pounded on rocks when climbing; it's been buried in the snow for hours, and it has never missed a beat. I have had this watch about five years, and I use it all day, every day.
My P6506 is slightly different than the picture in that it has military time printed under the main numbers (i.e. there is a small 13 under the 1, a 14 under the 2, etc.). Also, the "traser" is not printed on the dial. Otherwise, this is the same watch: sapphire crystal, titanium case, and carbon fiber bezel make this a lightweight watch that is also tough. It is a quartz movement, so it keeps accurate time, and never really needs to be adjusted. I move time zones a lot, so I am constantly changing the time, but for a non-atomic watch it's accurate.
After five years of hard use, the bezel has started to wear a bit at the edges, and the case has a few scratches. The crystal is perfectly clear, as it is very difficult to scratch sapphire with anything but sapphire or a diamond. I have changed the band a few times, but it takes a standard 22mm band, so it's easy to find them at Walmart or watch store.
Of course, the draw of this watch over others is that the hands and dots glow extremely bright. I find that most watches are useless after several hours in the dark. When you have 12 or more hours of darkness during winter camping, most watches won't let you see the time without a flashlight. This watch glows bright and does not need recharging like other forms of hand and dial illumination.
Overall, this is a great watch and well worth the money. It's it's too pricey, try one of the cheaper trasers. You can get a steel case and mineral coated glass for much less.
