+====== Swissonic ======
+{{wst>author|[[Foskett, Stephen|Stephen Foskett]] ([[https://grail-watch.com/|Grail Watch]])}}
+**Swissonic** was the marketing name used by [[ESA]] for their early [[electric]], [[tuning fork]], and [[quartz]] watch movements between [[1968]] and [[1977]].
+===== Overview =====
+[[Ebauches SA]] embarked on a number of different programs in the 1960s to develop alternative watch movements. These were advertised as "Swissonic" starting in [[1968]] and given various "levels" based on their technology
+  * Swissonic 10 [[Electric]] movements (e.g. [[ESA 9190|"Dynotron" 9190]])
+  * Swissonic 100 [[Tuning fork]] movements (e.g. [[ESA 9160|"Mosaba" 9160]])
+  * Swissonic 1000 First-generation [[quartz]] movements (e.g. [[ESA 9220]] and [[Beta 21]])
+  * Swissonic 2000 Second-generation [[quartz]] movements (e.g. [[ESA 9260]])
+Later, ESA simply used the term "Swissonic" to refer to any of their quartz movements, dropping the numbers. Many Swissonic movements were manufactured by ETA subsidiary [[Derby]], which also marketed complete watches and clocks using the [[Derby Swissonic]] name.
+This naming proved confusing, since it combined various technologies under one umbrella term. The "sonic" name also caused confusion, since it was often assumed to refer to [[tuning fork]] technology specifically. The company abandoned the term in [[1977]] as quartz movements became mainstream and well after production of electric and tuning fork movements ceased. ESA and [[ETA]] later turned to terms describing the dimensions of the movement, such as [[Flatline]] and [[Gabarit]]. In the 1980s, ETA coined a similar term to differentiate its mechanical movements, [[Mecaline]].
+===== History =====
+The most basic was the [[electric]] range, which used a battery and motor instead of a [[mainspring]] to power a conventional balance wheel movement. The production models were the compact [[ESA 9190]] and [[ESA 9200]] and larger [[ESA 9154|ESA 9154 and 9158]]. These would become known as "Dynotron" or **Swissonic 10**.
+ESA licensed the [[Bulova Accutron]] technology in [[1968]], producing their own "[[Mosaba]]" [[tuning fork]] movement that same year. It operated at 300 Hz, slightly slower than the Accutron, but was otherwise similar. These movements were branded **Swissonic 100** and included the [[ESA 9160|ESA 9160, 9162, and 9164]] as well as the [[chronograph]] [[ESA 9210]].
+The most advanced range of Swissonic movements were the [[quartz]] models, available in analog, [[LED]], and [[LCD]] versions. Analog movements include the compact [[ESA 9220|ESA 9220 and 9240]], rectangular [[ESA 9170]] ([[Beta 21]]), and round [[ESA 9180]], all of which were marketed as **Swissonic 1000**. ESA later developed the 11.5 ligne [[ESA 9362]] and [[ETA]] created the 12.5 ligne [[ETA 940.111]]. ESA's LCD movements began with the [[ESA 9260]] developed with Texas Instruments (marketed as **Swissonic 2000**) and later included the compact LED [[ESA 9376]] and 11.5 ligne LED [[ESA 9380]]. ESA also produced the LCD [[ESA 9315]].
+A new generation of quartz movements appeared in [[1976]]. These were simply called "Swissonic", even though they did not share much with the previous movements. All used a 32 KHz quartz oscillator imported from Japan, a Swiss-made Lavet stepping motor originally patented by [[Léon Hatot]] of Paris, and an integrated circuit from [[Faselec]] in Zurich. [[ESA 9362|Cal. 9362]] was based on the mechanical [[ETA 2870|Cal. 2870]], while [[ETA 940.111|Cal. 940.111]] was based on the then-new [[ETA 2892|Cal. 2892]]. The latter was commercialized by [[ETA]] and would be the basis for their [[ETA Flatline]] quartz family. The next year, ETA stopped using the Swissonic name.
