Generale Ressorts high-quality Swiss-made mainspring (GR3197X), compatible with ETA 2670, 2671, 2678, 2681, and Tissot 2381.

The ETA 2671 and similar movements were the Swiss "workhorses" used in classic Swiss ladies automatic watches. If you're servicing a 2671 (or similar) movement, you want to use a high-quality mainspring from a reputable manufacturer. Why take chances with a no-name mainspring that might cause fitment issues with the arbor or barrel, or which might not provide a strong amplitude? Generale Ressorts, of Switzerland, is the highest-quality maker of aftermarket mainsprings. 

Amplitude Watch Parts ships from the USA, so there's no need to worry about long shipping delays or tariffs.
