A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps, or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain.
A timer or countdown timer is a type of clock that starts from a specified time duration and stops when reaching 00:00. A simple timer is an hourglass. Commonly, a timer triggers an alarm when it ends. A timer can be implemented through hardware or software. Stopwatches operate in the opposite direction, upwards from 00:00, measuring elapsed time since a given time instant. Time switches are timers that control an electric switch.
A stopwatch is a timepiece designed to measure the amount of time that elapses between its activation and deactivation.
A chronograph is a specific type of watch that is used as a stopwatch combined with a display watch. A basic chronograph has an independent sweep second hand and a minute sub-dial; it can be started, stopped, and returned to zero by successive pressure on the stem. More complex chronographs use additional complications and can have multiple sub-dials to measure seconds, minutes, hours and even fractions of a second. In addition, many modern chronographs use moveable bezels as tachymeters for rapid calculations of speed or distance. Louis Moinet invented the chronograph in 1816 for use in tracking astronomical objects. Chronographs were also used heavily in artillery fire in the mid to late 1800s. More modern uses of chronographs involve aircraft piloting, auto racing, diving and submarine maneuvering.
The G-Shock is a line of watches manufactured by the Japanese electronics company Casio, designed to resist mechanical stress, shock and vibration. G-Shock is an abbreviation for Gravitational Shock. The watches in the G-Shock line are designed primarily for sports, military and outdoors-oriented activities; all G-Shocks have a chronograph feature, 200 metre water resistance and an alarm, with either a digital display, analogue display or a combination of analogue and digital displays. Other features such as a countdown timer, world clock, and a backlight are included in most models. Newer high-end models in the line also feature GPS, directional, pressure and temperature sensors, radio-controlled time adjustment and Bluetooth time adjustment achieved by connecting the watch to a smartphone via a dedicated application.
A soft key is a button flexibly programmable to invoke any of a number of functions rather than being associated with a single fixed function or a fixed set of functions. A softkey often takes the form of a screen-labeled function key located alongside a display device, where the button invokes a function described by the text at that moment shown adjacent to the button on the display. Soft keys are also found away from the display device, for example on the sides of cellular phones, where they are typically programmed to invoke functions such as PTT, memo, or volume control. Function keys on keyboards are a form of soft key. In contrast, a hard key is a key with dedicated function such as the keys on a number keypad.
The Canon EF is a manual focus 35mm single-lens reflex camera produced by Canon between 1973 and 1978. It was compatible with Canon's FD-mount lenses. The EF was built as an electro-mechanical version of Canon's top-of-the line wholly mechanical Canon F-1. The shutter is mechanical at all speeds ½ second and faster, but at 1 second and longer the shutter is all electronically controlled, allowing AE exposures from 1/1000 to 30 seconds. The EF shares the F-1's rugged construction and tough metal body. Unlike the F-1, the EF does not support any motor drive for film transport. Neither does it provide any interchangeable viewfinder.
The Casio FX-7000G is a calculator which is widely known as being the world's first graphing calculator available to the public. It was introduced to the public and later manufactured between 1985 and c. 1988. Notable features are its ability to graph functions, and that it is programmable. The calculator offers 82 scientific functions and is capable of manual computation for basic arithmetic problems.
The Casio F-91W is a digital watch manufactured by Japanese electronics company Casio. Introduced in June 1989 as a successor of the F-87W, it is popular for its low price and long battery life.
The Motorola F3, frequently known as the Motofone, is a candybar style GSM mobile phone from Motorola, released on 28 November 2006. It was the first mobile phone to use an electronic paper display.
The R-Zone is a portable game console developed and manufactured by Tiger Electronics. The R-Zone was shown at the American International Toy Fair in February 1995, and was released later that year. The R-Zone was panned by critics, and was also a commercial disaster, with its lifespan lasting only two years before being discontinued in 1997. Although the R-Zone was not designed to compete directly with any other handhelds, it marked Tiger Electronics' first multi-game entry into the portable electronic game market.
Timex Datalink or Timex Data Link is a line of early smartwatches manufactured by Timex and is considered a wristwatch computer. It is the first watch capable of downloading information wirelessly from a computer. As the name implies, datalink watches are capable of data transfer through linking with a computer. The Datalink line was introduced in 1994 and it was co-developed with Microsoft as a wearable alternative to mainstream PDAs with additional attributes such as water resistance, that PDAs lacked, and easy programmability. The watch was demonstrated by Bill Gates on 21 June 1994 in a presentation where he downloaded information from a computer monitor using bars of light and then showed to the audience the downloaded appointments and other data. The early models included models 50, 70, 150 and model 150s. The model numbers indicated the approximate number of phone numbers that could be stored in the watch memory. These early models were, at the time of their introduction, the only watches to bear the Microsoft logo. The watches have been certified by NASA for space travel and have been used by astronauts and cosmonauts in space missions. There had been an evolution over the years as to the number and type of entries that can be stored in the various watch models as well as the mode of data transfer between computer and watch. At the time of its introduction the watch was considered high-tech.
The Samsung SGH-U600, introduced in 2007, is a mobile phone manufactured in South Korea by Samsung and is part of the Ultra Edition II series of Samsung phones.

The Rubik's Revolution is a handheld electronic game invented, designed, developed and patented by Rehco, LLC, a Chicago toy and game inventing firm. The Rubik's Revolution was formerly distributed by Techno Source and received the 2008 TOTY Game of the Year Award. 11-12 years later, it would be revamped by Techno Source's parent company, Super Impulse and be regarded as one of the many toys that would help battle boredom in the Covid-19 Pandemic according to Time To Play Mag Designed to resemble the classic Rubik's Cube puzzle, the device is a single rigid cube; it is about as large as a Professor's Cube, with each face subdivided into 9 square sub-faces. The center square of each face features a recessed LED-lit button colored to correspond with the stickers on the remaining squares. Gameplay involves pressing the buttons when they light up, or when directed to by the game's recorded voice.
