What distinguishes it
Look beyond the reference.
Its 4 Hz rate and 25.60 mm casing diameter make it a useful comparison with the ETA 2824-2. The movement execution and the watchmaker’s regulation matter when judging timekeeping.
For the enthusiast
The suffix matters: do not transfer reserve figures from later SW200 versions onto the SW200-1. Shared dimensions also do not guarantee every part is interchangeable.
