The 104 St Sa A is a classic pilot watch in the SINN tradition.

The dial is clearly structured, with its three hands providing optimum readability of the time, date and day of the week down to the second. The pilot's bezel with minute ratcheting can be rotated on both sides and is securely attached to the case. It has a luminous triangle as key mark at the 12 o'clock position. The instrument watch has a polished stainless steel case and a crystal made of sapphire crystal which is also used for the transparent back. The transparent back allows the filigree work of the mechanical movement to be admired in all its intricacy. The 104 St Sa A is low pressure resistant and can withstand pressures of up to 20 bar.
