A traditional pilot watch designed in true, traditional SINN style. Accordingly, our 104 St Sa I MG model presents a clear structure, thus offering optimum readability of the time, date and day of the week.
For this model, we chose a distinctive colouring with a shimmering metallic-green dial. The instrument watch features a polished stainless-steel case. The crystal and transparent back made of sapphire crystal allows the accuracy of the mechanical movement to be admired. The pilot’s bezel with minute ratcheting can be rotated on both sides and is securely attached to the case. Its key mark is a luminous triangle.
The 104 St Sa I MG model is resistant to low pressure, waterproof and can withstand pressures of up to 20 bar.
