The quartz crisis was the upheaval in the watchmaking industry caused by the advent of quartz watches in the 1970s and early 1980s, that largely replaced mechanical watches around the world. It caused a significant decline of the Swiss watchmaking industry, which chose to remain focused on traditional mechanical watches, while the majority of the world's watch production shifted to Japanese companies such as Seiko, Citizen, and Casio which embraced the new electronic technology.
The quartz crisis took place amid the global Digital Revolution (or "Third Industrial Revolution") which was gaining momentum during the late 1950s. The crisis started with the Astron, the world's first quartz watch, which was introduced by Seiko in December 1969. The key advances included replacing the mechanical or electromechanical movement with a quartz clock movement as well as replacing analog displays with digital displays such as LED displays and later liquid-crystal displays (LCDs). In general, quartz timepieces are much more accurate than mechanical timepieces, in addition to having a much lower sale price.
During World War II, Swiss neutrality permitted the watch industry to continue making consumer time-keeping apparatus, while the major nations of the world shifted timing apparatus production to timing devices for military ordnance. As a result, the Swiss watch industry enjoyed an effective monopoly. The industry prospered in the absence of any real competition. Thus, prior to the 1970s, the Swiss watch industry had 50% of the world watch market.
In the early 1950s a joint venture between the Elgin Watch Company in the United States and Lip of France to produce an electromechanical watch – one powered by a small battery rather than an unwinding spring – laid the groundwork for the quartz watch. Although the Lip-Elgin enterprise produced only prototypes, in 1957 the first battery-driven watch was in production, the American-made Hamilton 500.
In 1954, Swiss engineer Max Hetzel developed an electronic wristwatch that used an electrically charged tuning fork powered by a 1.

In horology, the term electric watch is used for the first generation electrically-powered wristwatches which were first publicly displayed by both Elgin National Watch Company and Lip on March 19, 1952, with working laboratory examples in Chicago and Paris. The Hamilton Watch Company would be the first to produce and retail an electric watch beginning in 1957, before the commercial introduction of the quartz wristwatch in 1969 by Seiko with the Astron.
Bulova is an American timepiece manufacturing company that was founded in 1875 and has been owned by Japanese multinational conglomerate Citizen Watch Co. since 2008. The company makes watches, clocks and accessories, and it is based in New York City. Bulova was founded and incorporated as the J. Bulova Company in 1875 by Bohemian immigrant Joseph Bulova. It was reincorporated under the name Bulova Watch Company in 1923, became part of the Loews Corporation in 1979, and was sold to Citizen at the end of 2007.
is a Japanese multinational electronics manufacturing corporation headquartered in Shibuya, Tokyo, Japan. Its products include calculators, mobile phones, digital cameras, electronic musical instruments, and analogue and digital watches. It was founded in 1946, and in 1957 introduced the first entirely compact electronic calculator. It was an early digital camera innovator, and during the 1980s and 1990s, the company developed numerous affordable home electronic keyboards for musicians along with introducing the first mass-produced digital watches.
Explores the design and scaling of electromagnetic actuators for optimal energy extraction and power output, including considerations for thermal limitations and manufacturing constraints.
It appears that the concerted efforts of the watchmaking industry are leading towards a limit in mechanical watch accuracy. The general consensus in horology is that the time base's quality factor, a dimensionless number that characterizes the oscillator d ...
Scanning Near-field Optical Microscopy (SNOM) technique enables to overcome Abbe diffraction limit of far-field optics as well as to obtain simultaneously optical and topographical images. While the optical resolution of the method is limited by the apertu ...
The aim of this project is to deposit a thin film of aluminum nitride (AlN) or aluminum scandium nitride (AlScN) on a quartz substrate showing good piezoelectric properties for use in tuning fork oscillators. Quartz oscillators are commonly used in various ...
