====== ETA 2894-2 ======
{{wst>image_cr|ETA|2894-2}}

The **ETA 2894-2** is an automatic [[chronograph]] calibre by [[ETA]]. It was introduced in [[1996]] and remains in production [[as of 2019]].

===== Overview =====
The 2894 is unusual in that it is not derived from the [[Valjoux 7750]], which is the basis for most of ETA's chronograph movements. Instead, like the [[ETA 2094]], the 2894-2 is a modular design pairing a traditional base with a self-contained chronograph module. In this case, the 2894-2 is based on the low-profile [[ETA 2892-2]].

The 2894 is somewhat smaller than the 7750 family, measuring 12½ [[ligne]]s (28.00 mm) in diameter and 6.10 mm high compared to the typical 13¼ [[ligne]]s (30.00 mm) diameter and 7.90 mm height of the 7750 family.

Unlike the Valjoux, which can be serviced by a watchmaker, the 2894-2 chronograph module is only serviceable by the factory. Repairs typically consist of replacing the module entirely.

Mechanical movement with [[automatic]] winding, ball-bearing rotor, [[hacking seconds]], [[small second]] at the "3", [[chronograph]], date display at the "4" with [[quickset]] feature. It is sold by [[TAG Heuer]] as their "Calibre 17".
