About the price index 104 St Sa Sinn
The Sinn 104 St Sa is a pilot's watch that appeared in 2013, conceived in the German Maison's Flieger spirit: immediate legibility, a bidirectional bezel with minute detents, a 41 mm steel case, anti-reflective sapphire crystal, and 200 m water resistance. Powered by a Sellita SW220-1 type automatic day/date movement, it combines daily wear with a very distinctive horological identity. On the European pre-owned market, the Sinn 104 sells well because it offers a clear positioning: a genuine, versatile, robust, and recognised pilot's watch, with sustained demand for German pieces featuring functional design. Its value depends primarily on the condition of the case and bracelet, the presence of the box and papers, the dial version, as well as the bezel and case back finishes. Very clean examples, lightly polished, and the most sought-after series or variants naturally fall into the higher end of the market.

Reading the 104 St Sa Sinn price guide
The range observed for 104 St Sa Sinn runs from €1,300 to €2,500, with a median of €1,750 — a 1.9× gap between entry-level examples and the most sought-after ones. That spread is normal: on this model, condition, material and year weigh more heavily than the reference itself.
In practice, a piece below the median usually shows accepted signs of wear or a common configuration; above it you find rare colours, precious hardware and complete sets with the original box and invoice.
What pushes the 104 St Sa price guide up
- Full set: box, warranty, spare links and original invoice
- Unpolished case, original edges and a dial with no relume
- Exact year and reference (dial transition, calibre)
- Recent service documented by an approved watchmaker
Selling a 104 St Sa Sinn at the right price
We offer two options on this model. Outright purchase, settled within 72h once the piece is authenticated, suits anyone who wants an immediate exit. Consignment aims for the top of the range: the piece is photographed, promoted and sold with a commission that decreases with your membership card.
The pre-owned watch market has normalised since the 2022 peaks: steel sports references keep a premium, while gold and dress models currently offer the best entry points.
How we authenticate a 104 St Sa Sinn piece
Every piece that joins Monogram Paris follows the same protocol in our Paris workshops: no catalogue photography, no supplier imagery, only shots of the actual item.

- Dial, indexes and hands: printing, luminova and any relume documented
- Movement opened by a watchmaker: calibre, finishing, service parts

Care and storage

- Water resistance test after every case opening
- Avoid magnetic fields (speakers, magnetic bags, tablets)
