Calibre C01.211 is an inexpensive automatic chronograph movement made by ETA for Tissot since 2008.


The Lemania 5100 was a legendary workhorse of a movement, constructed from stamped steel, delrin plastic, and other simple materials. It was designed to compete with emerging inexpensive movements from Seiko and others, and to be cheap to assemble and service. It features a "6-9-12" arrangement of subdials but moves chronograph minutes to the central axis, giving watches using this movement a distinctive "four-handed" look. Although quite successful, the Lemania 5100 was not suitable for display casebacks and did not adapt well to additional complications. It went out of production in 2002, replaced by the more attractive and conventional predecessor Cal. 1350.

In 2008, Tissot requested a low-cost mass-produced chronograph movement for entry-level Swiss watches. ETA created this Cal. C01.211 based on the Lemania 5100 design. It was simplified and re-worked to be more attractive, with plates and bridges finished in a more refined manner. Additionally, jewel count was reduced to 15, operation slowed to 21,600 A/h, and the minute counter was moved to the 12:00 position. This made it a more conventional movement, functioning similarly to the common ETA 7750.

Variations on this movement design include:
