Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A Watchclock is a mechanical clock used by security guards as part of their Guard tour patrol system which require regular patrols. The most commonly used form used to be mechanical clock systems that required a key for manual punching of a number to a strip of paper inside with the time pre-printed on it. Recently, electronic systems have risen in popularity due to their light weight, ease of use, and downloadable logging capabilities. Watchclocks often had a paper or light cardboard disk placed inside for each 24-hour period. The user would carry the clock to each checkpoint where a numbered key could be found (typically chained in place to ensure that the user was physically visiting each point). That key would then be inserted into the clock where it would make an imprint in the disk. At the end of the shift or 24-hour period an authorized person (usually someone in a supervisory position above the patroller) would unlock the watchclock and retrieve the disk.
