The 104 St Sa A G is a classic pilot watch designed to convey a deep-rooted sense of SINN tradition. This timepiece is also characterized by its shimmering metallic-green dial. A total of 500 of these watches are being produced, each with an engraved limited-edition marking on the rotor.
Optimal readability of the date and weekday, along with the time, is ensured on the 104 St Sa A G by its clearly structured design. A special technical feature is the captive pilot’s bezel with minute ratcheting, which can be rotated on both sides and is securely attached to the case.
The crystal made of sapphire crystal is set in a polished stainless-steel case. The transparent back, which is also made of sapphire crystal glass, allows the delicate work of the mechanical movement to be admired in all its intricacy.
The 104 St Sa A G is resistant to low pressure and can withstand pressures of up to 20 bar.
