Sinn’s commitment to device, pilot and military watches is irrefutable. The brand is one of the primary experts in this field, with a full scope of straightforward, vigorous and successful watches at sensible costs. References, for example, the 103, the 140 or the 356 need no presentation any longer. Be that as it may, if there was simply one to remember, this would be the “Bundeswehr Chronograph for Pilots”, known under the references 1550 SG (when it was made by Heuer) or 155 Bw (when fabricated by Sinn). This watch, delivered during the 1960s, and later during the 1980s and mid 1990s, is a legend among military chronographs… And today, it’s back! Meet the new Sinn 158 Chronograph.

1960s-1990s – The Original Bundeswehr 1550 SG and the Sinn Model 155 Bw

The Bundeswehr watch was intended for military pilots and made for the West German Federal Defense Force (Bundeswehr). It was at first made by a company called Leonidas, which was subsequently bought by Heuer. It was driven by a Valjoux manual-wind type 222 with Incabloc stun assurance, 36-hour power hold, flyback work and hacking highlight. It was recognized as a Heuer-Leonidas development and would ultimately be supplanted by the comparative type 230.

The watch highlighted two pushers for the chronograph capacities with two subdials. The counter at nine o’clock showed continuous seconds while the dial at three o’clock was a 30-minute counter. Larger than average Arabic numerals, straight hands and a “Concorde”- molded tip for the chronograph clear seconds hand all combined to make a remarkably intelligible watch.

However, the mark plan component was the bezel. The watch had an unmistakable, very wide, dark bi-directional bezel with a semi-matte completion, an enormous, white triangle at its zero point and Arabic numerals at 15, 30 and 45.

Sinn’s job in this story happened during the 1980s and mid 1990s when Mr Helmut Sinn bought eliminated watches from the inventories of the Bundeswehr and sold these subsequent to reconditioning with, entomb alia, added SINN lettering on the dial under the mark “Bundeswehr Chronograph for Pilots” as the Model 155 Bw.

It was during this period that the glowing materials were transformed from the previous radioactive substance to something more secure, henceforth the dials with “3H” (Hydrogen-3) to indicate the change. A few renditions of the dial likewise incorporated a little “t” on top of the 6 o’clock file that additionally alluded to the presence of tritium.

All watches were fitted with a “Bund” style twofold layer lash, which was intended to secure the pilot’s skin on account of extraordinary temperatures. They were delivered from 1967 to 1990 when Germany was reunified, and the Bundeswehr was restructured.

2005, 2008, 2019 – The Sinn Bundeswehr Re-Editions

While the German brand actually has some military-propelled pilot’s watches in its inventory, for the most part with the 103St (indeed, it is a mark model), the genuine Bundeswehr watch was just re-altered twice by the brand, in exceptionally restricted batches.

In 2005, Sinn made a 200-piece re-version of the Bundeswehr watch for the Japanese market. The production discovered 200 extra cases expected for military watches and set up them with a hand-wound Valjoux 7760 development. The watch included similar dark dial with radiant hands and numerals (Super-LumiNova) and an indistinguishable Bund strap.

The 2005 Sinn 155 Bundeswehr made for the Japanese market ref. 155.020 (200-piece Limited Edition) 2008 Sinn 155 Bundeswehr made for Manufactum ref. 155.030 (272-piece Limited Edition)

In spite of the fact that the case, bezel and hands were indistinguishable from the military watches, this time the dial included a day and a date window at 3 o’clock.

In 2019, along with watch magazine Revolution, Sinn relaunched a watch enlivened by this military/pilot chronograph, the 155 Bundeswehr “Dim Star”. Obviously, this extremely restricted watch was, indeed, the base for the authority rendition done by the brand, the accompanying Sinn 158 Chronograph.

Bund 2020 – the Sinn 158 Chronograph

Gauging the accomplishment of the 2019 Revolution variant, it was simply a question of months before Sinn dispatched its own adaptation of the “Bundeswehr Chronograph”. Yet, let’s not shroud our delight, as by and by, this is a serious cool watch that has recently been released.

The plan of the Sinn 158 Chronograph Pilot is with regards to its archetype. As a matter of first importance, the case holds the 43mm distance across of the original watch – curiously large in those days, more conventional on the current market.

All the rest is dedicated to the 1550 chronograph, which means a completely globule impacted treated steel case, a dark covered matte pilots bezel, bi-directional and with hour long scale – with a similar design as the original – and a domed stun safe acrylic glass on top. As a piece of gear for military pilots, the watch is likewise impervious to pressure drops and water-impervious to 100m.

Even however the technicians have developed definitely since the 1960s, the new Sinn 158 Chronograph holds its dial format, with a bi-compax show with little seconds at 9 o’clock and 30-minute counter at 3 o’clock. As an admission to innovation and day by day wearability, a date work has been included a window situated at 6 o’clock – a more regular citizen model than the original, no doubt.

This new model, nonetheless, feels more contemporary, sportier and less “military oriented” than the original. While the enormous Arabic numerals look recognizable – same textual style as the 1550 – the rest has been refreshed. The matte dark dial includes a more definite seconds track and various hands, completely covered in white radiant paint (hours and minutes) or painted in red (for the chronograph signs). No vintage needle hands and fauxtina here.
