The oldest surviving clock in England is that at Salisbury Cathedral, which dates from 1386. A clock erected at Rouen, France, in 1389 is still extant, and one built for Wells Cathedral in England is preserved in the Science Museum in London. The Salisbury clock strikes the hours, and those of Rouen and Wells also have mechanisms for chiming at the quarter hour. These clocks are large, iron-framed structures driven by falling weights attached to a cord wrapped around a drum and regulated by a mechanism known as a verge (or crown wheel) escapement. Their errors probably were as large as a half hour per day. The first domestic clocks were smaller wall-mounted versions of these large public clocks. They appeared late in the 14th century, and few examples have survived; most of them, extremely austere in design, had no cases or means of protection from dust.
Wall clocks can be anything to anyone. Sure, they are made to tell time and they do that well, and if that was the only reason people wanted a wall clock for their home, there wouldn't be thousands of them offered by Wayfair. From kitchen wall clocks that are functional and decorative to oversized wall clocks to be placed over a grand fireplace paired with high ceilings for strictly decor - there are all kinds of wall clocks in the selection available from Wayfair. Their utility doesn't stop just because they are based on the principle of telling time; in fact, that reality has become a secondary attribute. Considering the array of designs that wall clocks come in, from theme clocks, kitchen wall clocks, clocks with timeless messages, starburst clocks, and so many others, it would take an entire page just to list them! Here are some great styles and uses for them to help guide you through your shopping.
This looks like a Death Star droid out of a Star Wars movie, but it gets the job done with the tricks up its sleeve. Charge your phone and your tablet at the same time with two power outlets and two USB ports. The alarm clock feature is simple, and while it also projects your tunes via Bluetooth audio, it comes with a surge protector. That’s right; no freak lightning storm is allowed to hold you back. CubieBlue Charging Bluetooth Speaker is still going to work when you plug it back in (even if you threw it across the room).

In Chinese culture, giving a clock (送鍾/送钟, sòng zhōng) is often taboo, especially to the elderly as the term for this act is a homophone with the term for the act of attending another's funeral (送終/送终, sòngzhōng). A UK government official Susan Kramer gave a watch to Taipei mayor Ko Wen-je unaware of such a taboo which resulted in some professional embarrassment and a pursuant apology.
The word horologia (from the Greek ὥρα, hour, and λέγειν, to tell) was used to describe early mechanical clocks, but the use of this word (still used in several Romance languages)  for all timekeepers conceals the true nature of the mechanisms. For example, there is a record that in 1176 Sens Cathedral installed a ‘horologe’ but the mechanism used is unknown. According to Jocelin of Brakelond, in 1198 during a fire at the abbey of St Edmundsbury (now Bury St Edmunds), the monks 'ran to the clock' to fetch water, indicating that their water clock had a reservoir large enough to help extinguish the occasional fire. The word clock (from the Celtic words clocca and clogan, both meaning "bell"), which gradually supersedes "horologe", suggests that it was the sound of bells which also characterized the prototype mechanical clocks that appeared during the 13th century in Europe.
"Stripe Clock" is a modern metallic design created by the artist, Belle. Measured at 24 inches on each side, this metal art is made from a single sheet of metal expertly grinded and tinted and made in to a functional clock. It is mainly characterized by the bright stripe in the middle of the sheet of metal. Each stroke and grind pattern on this piece accentuates the beauty of the plain sheet of metal. The glimmer coming from the shallow grinds are like street lights illuminating the city in the...

Islamic civilization is credited with further advancing the accuracy of clocks with elaborate engineering. In 797 (or possibly 801), the Abbasid caliph of Baghdad, Harun al-Rashid, presented Charlemagne with an Asian Elephant named Abul-Abbas together with a "particularly elaborate example" of a water clock. Pope Sylvester II introduced clocks to northern and western Europe around 1000AD
The most accurate mechanical timekeeper is the Shortt pendulum clock; it makes use of the movement described above for electric master clock systems. The Shortt pendulum clock consists of two separate clocks, one of which synchronizes the other. The timekeeping element is a pendulum that swings freely, except that once every half minute it receives an impulse from a gently falling lever. This lever is released by an electrical signal transmitted from its slave clock. After the impulse has been sent, a synchronizing signal is transmitted back to the slave clock that ensures that the impulse to the free pendulum will be released exactly a half minute later than the previous impulse. The pendulum swings in a sealed box in which the air is kept at a constant, low pressure. Shortt clocks in observatories are kept in a room, usually a basement, where the temperature remains nearly constant, and under these conditions they can maintain the correct time to within a few thousandths of a second per day.
Strong, durable, super large time display makes the model perfect for those who either want a big number clock, or for visually impaired individuals who need extra-large numerals, The red LED display on a black background, makes the contrast ideal for easy viewing.

“This was a gift for my elderly, cognitively impaired mother. She was very often confused as to which day it was, the time of day, etc. She would show up at appointments on the wrong day, or think it was morning when it was evening. This clock is fantastic! It has made such a difference. Now she always knows what day and time it is. The clock is also very nice-looking. This was an excellent purchase and highly recommended. I can’t say enough good things about it.”
