Its defining details are the SW 510 M calibre, a matt black dial, and a tachymeter scale on the interior bezel. Here are the specifications and what they mean in use.
What is the Sinn 103 St Ty Hd?
It is a hand-wound chronograph in Sinn’s 103 pilot-watch series. Sinn describes the 103 as a classic pilot chronograph collection that has been part of its range since the 1960s. The 103 St Ty Hd brings that series format together with a matt black dial and a tachymeter scale inside the bezel.
Sinn’s catalogue for 2025–2026 gives the edition limit as 1,000 pieces. That is the manufacturer’s stated production limit; it does not establish how many have sold or whether the watch will appreciate on the secondary market. Sinn’s 103 St Ty Hd catalogue entry and its English product data sheet provide the model details.
What movement does it use, and is it hand-wound?
Yes. Sinn specifies the SW 510 M, a hand-wound calibre, and describes it as finely decorated. Hand-winding means the wearer winds the movement by turning the crown; it is not an automatic calibre that winds itself through wrist motion.

How do the dial and tachymeter work?
Black dial and luminous details
The matt black dial has faceted applied indices and faceted hour and minute hands. Sinn says luminous elements support legibility in low light. These features define the display; the product sheet does not provide a quantified brightness or legibility test.
Interior-bezel tachymeter
The tachymeter scale is positioned on the interior bezel and is intended for manual speed measurement from 60 to 600 km/h, according to Sinn’s English product sheet. A tachymeter is used with the chronograph: the wearer times a measured distance and reads the scale to estimate speed. It is not an electronic speed sensor or live speed readout.

What are the case and crystal specifications?

What the limited-edition status does—and does not—tell you
The 1,000-piece limit makes the 103 St Ty Hd a defined production edition rather than an unlimited catalogue model. It does not establish current availability, how many examples remain unsold, or future resale value. Sinn’s cited catalogue and product sheet do not state a current price or inventory status, so buyers should confirm both with a seller before making a purchase decision.
