The Sinn 156.1 E is a successful synthesis of tradition and modernity, making this historic pilot’s chronograph—limited to 300 pieces—unmistakably appealing. Its special charm lies in its contemporary interpretation of a timepiece that is highly regarded among watch enthusiasts. To appreciate the traditional background of the model 156.1 E, it’s important to note that its predecessor was the model 155. As the successor to that timepiece, Sinn developed the 156 and 156 MILITARY models—watches that have now become true icons.
60-Minute Stopwatch Hand from the Dial Centre:
The modern, innovative character of the 156.1 E is reflected in Sinn’s in-house chronograph movement SZ01, featuring a 60-minute stopwatch hand from the dial centre. The advantage is that stop times can be recorded more easily, quickly, and accurately—resulting in a significant improvement in readability. This movement is integrated into a newly designed case with a screw-in back, aesthetically modelled after its historical predecessors with a 43mm diameter sliding case. However, the 156.1 E model now features a sapphire crystal cover glass, which is more scratch-resistant than the acrylic glass used in the original model. The pilot’s bezel is captively connected to the case and can be smoothly rotated without detent—an innovation being introduced to the SINN range for the first time with the 156.1 model. The TEGIMENT Technology of the pilot’s bezel is also an essential prerequisite for applying the Hard Coating in anthracite, ensuring exceptional durability.
Date Display in the Form of the Kollsman Window of an Aviation Altimeter:
As a striking detail, the pilot’s rotating bezel, unlike historical models, has a luminescent fixed point at the twelve o’clock marking, making it possible to clearly identify the position of the set reference time in the dark. The numerals, as well as the hour and minute hands, are coated with ivory-coloured luminescent material. This contrasting application conveys a stylish vintage look and creates a further visual link to the watch’s historical roots. Enthusiasts of historical pilot’s chronographs will also appreciate the design of the date display at 3 o’clock, reminiscent of the Kollsman window of a barometric aviation altimeter used to set the reference air pressure. Similar to the reference pressure on the altimeter, this display must be manually adjusted to the location for the watch to function fully. The date window’s design emphasises the instrumental character of the watch and highlights the importance of the date for long-haul flights. By continuing proven elements while embracing the potential for innovation, the 156.1 E embodies a chronograph that is both traditional and modern.
