Sinn 203

Origin and development

Since the company was founded, Sinn has focused on instrumental wristwatches and pilot's watches. Right from the start, quality and value for money have been convincing in every respect. Sinn's high-precision timepieces were particularly in demand in the aviation industry. When the diving watch "Sinn 203" was launched, the collection was an excellent addition to the company's instrument watches.

Special Editions

In the meantime, in addition to the original model, other special editions such as the 203 Arctic became available on the market. Depending on availability, it is worth taking a look at the second-hand market. As the name suggests, the 203 Arctic is once again a jubilee model in the collection to mark 45 years of the company's existence. It is limited to just 450 pieces and has a titanium case. The dial is anthracite.

The Sinn 203 Arctic with temperature resistance technology

The Sinn 203 Arctic is the first diving chronograph with innovative temperature resistance technology. However, the timepiece is also visually impressive thanks to its polished stainless steel case and blue galvanized dial. This is UV-resistant so that the colour does not fade. This variation of the Sinn 203 scores like the other models with Ar-Dehumidifying Technology. In this way, the watch is extremely temperature-resistant. Thus, the 203 easily withstands fluctuations between 45 °C and +80 °C.

Features of the Sinn 203 Arctic

  • Diver's rotating ring with minute detent
  • Sapphire crystal cover glass
  • Solid or visible sapphire crystal back
  • Pressure resistant up to 30 bar or 20 bar with a sapphire glass back
