This is an early ETA 2824-2 powered example, highly regarded by enthusiasts and collectors for its proven Swiss movement and robust reliability.

The watch is in excellent overall condition, reflecting careful ownership with only light signs of use consistent with its age. The sapphire crystal is clean, all functions operate correctly, and the movement runs smoothly.

The Sinn 556 has earned its reputation as one of the benchmark everyday mechanical watches, combining understated German design, exceptional legibility and versatile wearability. At 38.5 mm it is equally suited to casual wear or a business environment and remains one of Sinn's most iconic references.

A complete ETA-powered example with documented provenance and original purchase invoice is becoming increasingly difficult to find.

The watch can be viewed by appointment.
