Chronos Digital Chess and Game Clock

I have tried many different kinds of chess clocks and these are simply the best. Every chess player who I know agrees: there is simply no other clock that is equal to the Chronos.I have two Chronos chess clocks that I have had for about 5 and 8 years respectively. These clocks are extremely sturdy. One of the clocks has been kept in my car for years so that I always have it there during my weekly visits to my chessclub, etc. This clock has endured extreme summer heat and winter cold over the years without any noticeable effect on it. I have dropped one of the clocks onto a concrete floor from a height of well over a yard without any detectable damage to the clock at all.The clock case is made of aluminum that seems to be about 2 mm in thickness. The internal workings are solidly attached to the inside top of the clock case in a manner that makes it unlikely that they will be damaged by jostling or dropping the clock. The battery pack is attached to the inside bottom of the case and the batteries last for about 3 years of pretty heavy use (it will also turn itself off after a certain length of time to preserve the batteries if you forget to do so).Note that there are several different versions of the Chronos clock. You can get these clocks with different kinds of buttons: with touch buttons and also with click buttons (and you can even find a variety of colored replacements for the click buttons). Both types of buttons are quite nice, albeit I personally prefer the click version since I like tactile confirmation that I have successfully punched the clock and I also like the option of punching the clock with a captured piece which does not work on the touch version since it must sense the conductivity of the skin on your finger. Note that the touch version is super sensitive and your finger barely has to graze the button to punch it and some players prefer the touch version because of this.One of the great strengths of the Chronos is that it has very few movable parts (nothing moves but the buttons) that can break down. You turn the clock on by holding the middle button on top for a moment and you freeze it by hitting the same button once. All the other functions of the clock are programmed through different combinations of hitting the buttons, and you turn the clock off by hitting either side button five times.You can custom program the clock for twelve different presets variations of time and time delays. In addition, it comes with a variety of preset standard blitz and tournament times. The clock is extremely flexible, but you have to spend some time learning how to program it. It took me awhile to learn to program the clock and for the first few months I was always referring back to the manual for how to program different things on it. Once you get the hang of it though, it is quite intuitive and I have not looked at a manual for years now.Note that the latest version of the Chronos has one single time display window that stretches the entire length of the clock (not two small separate windows like shown on the picture here).You should also know that the price listed here seems rather high and you should be able to find this clock for about $90 from a variety of different online vendors.
