Xbox Series X and Series SThe Xbox Series X and Xbox Series S are, collectively, the fourth generation of the Xbox series of home video game consoles developed and sold by Microsoft. Released on November 10, 2020, the higher-end Xbox Series X and lower-end Xbox Series S are part of the ninth generation of video game consoles, which also includes Sony's PlayStation 5, released the same month. They superseded the Xbox One. In early 2019, rumors emerged of a fourth generation of Xbox consoles (codenamed "Scarlett") that consisted of a high-end model ("Anaconda") and a lower-end model ("Lockhart").
Balance wheelA balance wheel, or balance, is the timekeeping device used in mechanical watches and small clocks, analogous to the pendulum in a pendulum clock. It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, known as the balance spring or hairspring. It is driven by the escapement, which transforms the rotating motion of the watch gear train into impulses delivered to the balance wheel.
Xbox OneThe Xbox One is a home video game console developed by Microsoft. Announced in May 2013, it is the successor to Xbox 360 and the third console in the Xbox series. It was first released in North America, parts of Europe, Australia, and South America in November 2013 and in Japan, China, and other European countries in September 2014. It is the first Xbox game console to be released in China, specifically in the Shanghai Free-Trade Zone. Microsoft marketed the device as an "all-in-one entertainment system", hence the name "Xbox One".
Astronomical clockAn astronomical clock, horologium, or orloj is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the Sun, Moon, zodiacal constellations, and sometimes major planets. The term is loosely used to refer to any clock that shows, in addition to the time of day, astronomical information. This could include the location of the Sun and Moon in the sky, the age and Lunar phases, the position of the Sun on the ecliptic and the current zodiac sign, the sidereal time, and other astronomical data such as the Moon's nodes for indicating eclipses), or a rotating star map.
