====== ETA Thermoline ======
**Thermoline** is a family of thermo-compensated [[quartz]] movements from [[ETA]].

ETA boasts that Thermoline offers "twenty times the accuracy of standard quartz movements". They base this claim on their use of thermo-compensation and adjustment terminals, allowing fine adjustment in response to temperature changes as well as by a watchmaker.
