Sinn’s Latest Limited Edition: Purposeful, Blacked‑Out, and Surprisingly Priced

100 pieces. €3,990. Frankfurt’s Sinn keeps its tool‑watch brief short and strict: the 936 S is a pared‑back, all‑black bicompax chronograph that favours function over flash.

Design and case: stealth with Sinn’s tool‑watch DNA

The case is 42.5 mm of bead‑blasted stainless steel with a matte black Tegimented PVD finish for scratch resistance and low reflectivity. At 13.6 mm thick it slips under a cuff. Sinn fits a double‑domed sapphire crystal with anti‑reflective coatings on both sides and a smoked sapphire display back to show the movement. Water resistance is 100 metres. A tapered black leather strap with quick‑release spring bars completes the package.

Movement: Sinn’s in‑house bicompax calibre

The 936 S houses Sinn’s new in‑house automatic calibre, the SZ‑936. It uses a column‑wheel and a vertical clutch for crisp start/stop action, runs at 4 Hz (28,800 vph) and stores 60 hours of power thanks to an optimised mainspring barrel. The bicompax layout places a 30‑minute totaliser at 3 o’clock and running seconds at 9. Sinn also applies shock protection and anti‑magnetic measures consistent with its practical engineering.

“No gimmicks, just a focused execution of a modern, chronograph,” says the watch’s brief — and the watch delivers exactly that.

Dial, legibility and the blacked‑out aesthetic

The dial keeps the monochrome look purposeful: matte black surface with slightly recessed subdials, luminous baton hands and hour indices treated in muted Super‑LumiNova to preserve the stealth feel at night. Seconds and minute tracks are printed in darker grey to maintain low contrast while still allowing quick reading. The overall effect reads tactical and restrained, not novelty noir.

Market significance and availability

Limited to 100 individually numbered pieces, the 936 S is positioned as an attainable collector’s item within Sinn’s range. Distribution will run through Sinn’s Frankfurt boutique and select authorised dealers, with online orders opening in April 2026. At €3,990 and a manufacture column‑wheel chronograph inside, expect keen interest — decide quickly if you want one.
