The origin of the all-mechanical escapement clock is unknown; the first such devices may have been invented and used in monasteries to toll a bell that called the monks to prayers. The first mechanical clocks to which clear references exist were large, weight-driven machines fitted into towers and known today as turret clocks. These early devices struck only the hours and did not have hands or a dial.
The Howard Miller Brohman 625-618 Large Wall Clock has a brushed, warm brown finish and metallic undertones. At 34" in diameter with a 22" aged dial this clock will fit just about any decor. With large Roman numerals and black hands this clock will be a favorite for years to come. Highly accurate quartz movement requires one AA battery (Not Included).
This is the number-one selling kid's clock on Amazon, with more than 2,500 reviews. Parents rave about the restoration of their sleep time. Many parents say it "saved me from my early riser! Life changing!" Even parents of older children with developmental delays found the clock very useful in indicating to non-readers when it's okay to get up, and when it's not.
This massive iron wall clock is 49" in diameter and is finished in off-white with an antique nickel outer ring that is moderately distressed and dented for an aged appearance. Black Roman numerals are centered on individual antique off-white panels. Quartz, battery-operated movement requires one AA sized battery. Some assembly is required. One year warranty and Free Shipping.
Until advances in the late twentieth century, navigation depended on the ability to measure latitude and longitude. Latitude can be determined through celestial navigation; the measurement of longitude requires accurate knowledge of time. This need was a major motivation for the development of accurate mechanical clocks. John Harrison created the first highly accurate marine chronometer in the mid-18th century. The Noon gun in Cape Town still fires an accurate signal to allow ships to check their chronometers. Many buildings near major ports used to have (some still do) a large ball mounted on a tower or mast arranged to drop at a pre-determined time, for the same purpose. While satellite navigation systems such as the Global Positioning System (GPS) require unprecedentedly accurate knowledge of time, this is supplied by equipment on the satellites; vehicles no longer need timekeeping equipment.
In Europe, between 1280 and 1320, there is an increase in the number of references to clocks and horologes in church records, and this probably indicates that a new type of clock mechanism had been devised. Existing clock mechanisms that used water power were being adapted to take their driving power from falling weights. This power was controlled by some form of oscillating mechanism, probably derived from existing bell-ringing or alarm devices. This controlled release of power—the escapement—marks the beginning of the true mechanical clock, which differed from the previously mentioned cogwheel clocks. Verge escapement mechanism derived in the surge of true mechanical clocks, which didn't need any kind of fluid power, like water or mercury, to work.

Some predecessors to the modern clock may be considered as "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with the sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels.[1][2][3][4]
The Howard Miller Angelina 625-636 Wall Clock is part of Howard Millers New 91st Anniversary Edition of clocks. This clock has an aged look that is achieved through spatter marks, the use of a rasp, and well placed dents. The Antique White finish features brown undertones on select hardwood and veneers.

The dial has an aged look with black Arabic numerals that look worn and charcoal grey hands behind a glass crystal that is convex. One Year Warranty and Free Shipping.
Who doesn't love an alarm clock that verbally lets you know it's time to get up and start your day? Step aside, Siri, because "Reminder Rosie" is where it's at. You can easily record up to 25 different alarm-reminders at 6 seconds each. So why not wake up to a recording of your kids saying, "Good morning, Mom!"? (Or maybe you don't want that.) We love how you can turn off the alarm by quickly pressing a button or just saying out loud, "Reminder Off." 

Marathon's Atomic alarm clock with temperature and date is packed with features. It has an ambient light sensor, which allows the auto-night light to illuminate the display when necessary. With a soft amber LED, the large digit display is easy to read at night and becomes even brighter if the Snooze/Light button is pressed. At a glance you can easily see the time, date, day and temperature. The controls on the front of the clock allow you to easily set the alarm, switch between Fahrenheit or...
“The alarm is loud with a lower frequency melody which I like since I have high-frequency hearing loss. Guaranteed to wake anyone up when the alarm goes off which is super important to me, especially if I’m using the alarm clock to wake up to catch a flight. … When the alarm goes off, press the large snooze bar on the top to have the alarm go off again in five minutes. Pressing the snooze bar on top at anytime also lights up the numbers and bars on the clock’s face, but the hands are a bit hard to see in the dark since the hands don’t light up. When the alarm on/off switch is turned to the off position, there’s a cute voice that says ‘Good Morning!’ which brings a smile to start the day. We love this clock so much, we plan to buy more to give as gifts. We’re sure the recipients will love it as much as we do.”
