756 S

The Sinn 756 S is a standout in Sinn’s instrument chronograph lineup, known for its black Tegimented case and aviation-inspired design. Originally developed for pilots seeking maximum legibility and durability, this model’s matte black hard-coated finish and anti-reflective sapphire crystal give it a purposeful, stealthy look that collectors value. Its reputation for uncompromising tool-watch functionality makes it a favorite among those who appreciate Sinn’s technical innovations.

This 43mm chronograph houses the automatic Valjoux 7750 movement, offering reliable chronograph functionality and day-date display. The 756 S differs from the standard 756 by its full black Tegimented case and bracelet, which are more resistant to scratches than the bead-blasted steel of the regular version. Sinn’s Ar-Dehumidifying Technology and 200-meter water resistance add everyday practicality, making it a robust choice for active wear.

When buying a 756 S, condition of the black coating is a key value driver—look for examples with minimal wear, as re-coating is not straightforward. Early models may feature different bracelet options or dial details, but all share the signature left-side crown and pushers. Factory box, papers, and original bracelet boost collectability, while Sinn’s modular construction means authorized service is straightforward. This model rarely lingers on the market, especially in excellent condition.
