About This Watch:
The Sinn 556 A is the go-to entry point into German tool watches. At 38.5mm it wears smaller than the spec suggests thanks to the short lugs and sits flat on the wrist. The "A" denotes Arabic numerals versus the "I" version with indices. Built in Frankfurt with proper tool watch specs: 200m water resistance, antimagnetic protection, and shock resistance. The Sellita SW200 is a proven workhorse — same architecture as the ETA 2824 with easy serviceability. This example comes as a full kit with both the NATO and leather straps.
