This model is no longer available in our current range.
103 St Sa E

The classic pilot watches in series 103 are amongst the most traditional watches to be developed by our company. Their aesthetic design was and remains style-defining.

The 300-piece limited-edition 103 St Sa E is reminiscent of historical pilot watches with its luminous ivory-coloured coating on the hands, numerals and indices. Although classic in appearance, this SINN watch is every bit contemporary thanks to its high-tech features. For example, the 103 St Sa E has a captive pilot’s bezel with minute ratcheting, which is securely attached to the polished stainless-steel case. It is resistant to low pressure and can withstand pressures of up to 20 bar. The crystal and transparent back are made of curved sapphire crystal glass.
