556 Altherr

Striking lines, a minimalistic dial design and clear readability – with these typical SINN characteristics, the 556 Altherr special edition clearly demonstrates its affinity to on-board timekeeping instruments and consciously dispenses with the second hand and date display. The focus is on a heterogeneous California dial, which is exclusively available in the Altherr special edition. It is emphasised by the choice of colour of the luminous material and dial, which reflect the contrast of the Californian deserts by day and night.

Thanks to its 38.5 mm case, the 556 Altherr fits on every wrist. The satinised stainless-steel case underscores the sporty yet elegant appearance and is waterproof and pressure-resistant to 20 bar.

This exclusive timepiece features a crystal and transparent back made of sapphire crystal, allowing the delicate mechanical movement to be admired in all its intricacy. Just like the engraved limited-edition marking on the rotor.

With a production of just 100 pieces, this limited edition embodies the love of freedom.
