			The workhorse of the ETA mechanical line is the ETA 2824-2, The 2824 is an automatic winding, twenty-five jewel movement, available in four executions or grades: Standard, Elaborated (improved), Top and Chronometer.[4] The key components which differ at the line of demarcation between Elaborated and Top are the shock protection system (Elaborate=Etachoc/Top=Incabloc), balance wheel (Elaborate=Brass/Top=Glucydur) and the hairspring (Elaborate=Nivaflex 2/Top=Anachron). In contrast, since the addition of the "-2" at the end of the movement number, there has been no difference between the standard and the chronometer grades in terms of the regulator mechanism, both being Etachron. To illustrate the differences in accuracy garnered by the successive grades, consider the following specifications:

	The Valjoux 7750 uses a three-plane cam system, the coulisse-lever escapement, rather than the traditional chronograph mechanism, the column wheel. It is constructed of a mainplate, calendar plate, and chronograph top plate. Levers push a cam back and forth, driving the stopwatch mechanism of the Valjoux 7750. In the 1980s, many companies began using the Valjoux 7750 because it was easier to mass-produce and distribute in high-volume. The system and movement were developed by Edmond Capt in 1970, as a fully integrated self-winding mechanism with quick-set day/date based on the Valjoux 7733.
