SINN 103 Sa B E

The 103 Sa B E is a traditional pilot chronograph watch loaded with high-tech features typical of a SINN watch. Its stainless steel case with polished finish houses a blue dial featuring sunburst decoration. This timepiece takes inspiration from historical pilot watches with its luminous ivory-coloured coating on the hands, numerals and indices.

The blue dial with sunburst decoration and the anodised aluminium pilot’s bezel in blue gives the pilot chronograph a modern feel, without detracting from the functional character of the watch.

The profile of the highly curved sapphire crystal glass is similar to traditional acrylic glass. This sapphire crystal glass is ground out from an approximately 5 mm solid blank with five different curvature radii, and carefully polished. The grinding tools required to produce it have been made especially. The result of this complex process not only preserves the classic look of the glass, it also makes it highly resilient.

The 103 Sa B E is limited to 500 pieces, which is documented by the ‘Eine von 500’ (one of 500) engraving on the rotor.  The watch is resistance to low pressure and pressure resistance up to 20 bar.
