Sinn 556i
Founded in 1961 in Frankfurt am Main, Germany, Sinn has built a devoted following among watch enthusiasts who value engineering substance over marketing noise. The brand is perhaps best known for its instrument watches with genuine technical credentials — and the 556 series has become something of a modern cult classic, widely regarded as one of the finest everyday watches available at its price point.
The Sinn 556i, reference 556i, is a well-executed 38.5 mm satinised stainless steel sport watch with a beautifully clean lacquered black dial featuring painted rectangular luminescent hour indices and sword-shaped hands — a layout directly inspired by cockpit instrument design, with legibility at its absolute core. The date display sits neatly at 3 o'clock with a matching black date wheel, keeping the dial perfectly cohesive. At its heart beats the Sellita SW200-1 top-grade automatic movement, running at 28,800 vph with a power reserve of 38 hours — dependable, proven and easily serviceable. A flat sapphire crystal with anti-reflective coating protects the dial, while the sapphire exhibition caseback reveals the movement. Water resistance is rated at 200 metres. The watch is fitted on Sinn's signature H-link stainless steel bracelet — a uniquely comfortable and highly regarded bracelet design that enthusiasts consistently single out as one of the best in the industry.
This Sinn 556i is from 2024, is in near mint condition and comes as a full set.
