A successful synthesis of tradition and modernity is what makes this historic pilot's chronograph, limited to 300 pieces, so unmistakably appealing. Its special charm lies in its contemporary interpretation, which takes a timepiece that is very popular with watch enthusiasts as its model. To better understand the traditional background of the model 156.1 E, it is important to know that the original predecessor is the model 155 (see below). As the successor to this timepiece, our company developed the 156 and 156 MILITARY models (see below) - all watches that are now true icons.
60-minute stopwatch hand from the dial centre
The modern, innovative character of the model 156.1 E is reflected in our in-house chronograph movement SZ01, which features a 60-minute stopwatch hand from the dial centre. The advantage: stop times can be recorded more easily, quickly and accurately - a clear gain in terms of clear readability. This movement is integrated into a newly designed case with a screw-in back, which is aesthetically modelled on its historical predecessors with a 43 mm diameter sliding case. However, the 156.1 E model now has 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 rotated smoothly without detend - another innovation that is being introduced to the SINN range in this form for the first time with the 156.1 model. The TEGIMENT Technology of the pilot's bezel is also an important prerequisite for the application of the Hard Coating in anthracite, which proves to be extremely durable as a result.
Date display in the form of the Kollsman window of an aviation altimeter
As a striking detail, the pilot's rotating bezel, unlike the historical models, has a luminescent fixed point in the marking at twelve o'clock, which makes 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 covered with ivory-coloured luminescent colour. This type of contrasting application conveys a stylish vintage look and creates a further visual link to history. And lovers of historical pilot's chronographs will also be delighted: The design of the date display at 3 o'clock is reminiscent of the Kollsman window of a barometric aviation altimeter, which is used to set the reference air pressure. Similar to the reference pressure on the altimeter, this display must be manually adjusted to the location in order for the watch to function fully. Similar to the reference pressure on the altimeter, this display must be manually adjusted to the location in order for the watch to function fully. The design of the date window thus emphasises the instrumental character of the watch and at the same time the importance of the date for long-haul flights.
Continuing proven elements while utilising the potential for change: With the 156.1 E model, this design philosophy has created a chronograph that is both traditional and modern.

![Looking back: In the beginning was the Model 155](https://www.sinn.de/out/pictures/ddmedia/gravity/155_Bw_Archiv_scan_300dpi_Graustufen_ret.jpg?width=640&height=360&quality=100)
The historic Model 155 - a ‘wristwatch with double stop mechanism’ (the original designation used by the Bundeswehr - the German Armed Forces - in the 1960s) sold in very small numbers in the 1980s and early 1990s - is today one of the most sought-after collector's watches from our company. At the time, the company acquired decommissioned watches from the stocks of the Bundeswehr (Heuer-Leonidas SA 1550 SG, or Heuer 1550 SG for short) and sold them as the ‘Bundeswehr Chronograph for Pilots’ model 155 Bw.
![The successors: the 156 and 156 MILITARY models](https://www.sinn.de/out/pictures/ddmedia/gravity/Sinn156MILITARYohne24h.jpg?width=640&height=360&quality=100)
In the successor models 156 and 156 MILITARY - the latter with the corresponding lettering above the window for the day of the week and date - the case design was initially adopted in the form of an sliding case. Later, the chronograph was also offered with a traditional case design. The readability of the stopped time was ensured by the Lemania 5012 movement with the minute stop display from the centre, or later by the Lemania 5100 with 24-hour display and minute stop display from the centre. It was precisely this legendary movement that later served as the model for the new design of the SZ01 and which today performs its work reliably in the 156.1 model. Screw-in back, acrylic glass, shortened pushers and crown (in contrast to the predecessor model 155), which moved closer to the case and thus minimised damage in the event of impact, were further characteristics of the model series at the time.
