Sinn’s commitment to instrument, pilot and military watches is obvious. The brand is one of the fundamental experts in this field, with a full scope of straightforward, powerful and successful watches at sensible costs. References, for example, the 103, the 140 or the 356 need no presentation any longer. In any case, 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 made 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 security, 36-hour power save, flyback work and hacking highlight. It was recognized as a Heuer-Leonidas development and would ultimately be supplanted by the comparable type 230.
The watch included two pushers for the chronograph capacities with two subdials. The counter at nine o’clock showed constant seconds while the dial at three o’clock was a 30-minute counter. Curiously large Arabic numerals, straight hands and a “Concorde”- molded tip for the chronograph clear seconds hand all combined to make an especially neat watch.
However, the mark plan component was the bezel. The watch had an unmistakable, incredibly 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 in the wake of reconditioning with, bury 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 signify the change. A few adaptations of the dial additionally incorporated a little “t” on top of the 6 o’clock record that likewise alluded to the presence of tritium.
All watches were fitted with a “Bund” style twofold layer lash, which was intended to ensure 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 index, for the most part with the 103St (truth be told, 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-release of the Bundeswehr watch for the Japanese market. The assembling discovered 200 extra cases proposed 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 2008, Sinn made a second 272-piece restricted release reverence to the Bundeswehr watch, this time utilizing a programmed Valjoux 7750 for German vendor Manufactum. 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, together with watch magazine Revolution, Sinn relaunched a watch motivated by this military/pilot chronograph, the 155 Bundeswehr “Dim Star”. Obviously, this extremely restricted watch was, indeed, the base for the official adaptation done by the brand, the accompanying Sinn 158 Chronograph.
Bund 2020 – the Sinn 158 Chronograph
Gauging the accomplishment of the 2019 Revolution rendition, it was simply a question of months before Sinn dispatched its own variant of the “Bundeswehr Chronograph”. In any case, let’s not conceal our delight, as indeed, 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. Above all else, the case holds the 43mm measurement of the original watch – curiously large in those days, more customary on the current market. The watch isn’t slender either. It has a case thickness of 15.15mm because of the advanced programmed development inside. All the rest is devoted to the 1550 chronograph, which means a completely dab impacted hardened steel case, a dark covered matte pilots bezel, bi-directional and with hour long scale – with a similar format 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 specialists have advanced radically since the 1960s, the new Sinn 158 Chronograph holds its dial design, with a bi-compax show with little seconds at 9 o’clock and 30-minute counter at 3 o’clock. As an admission to advancement and day by day wearability, a date work has been included a window situated at 6 o’clock – a more non military personnel model than the original, no doubt.
This new model, nonetheless, feels more contemporary, sportier and less “military oriented” than the original. While the huge Arabic numerals look natural – same textual style as the 1550 – the rest has been refreshed. The matte dark dial includes a more point by point seconds track and various hands, completely covered in white glowing paint (hours and minutes) or painted in red (for the chronograph signs). No vintage needle hands and fauxtina here.
Powering this Sinn 158 Chronograph is a dependable, solid, effectively functional and available programmed chronograph dependent on the Valjoux 7750 design, and fabricated by Sellita. This type SW 510 beats at 28,800 vibrations/hour and stockpiles to 48 hours of force save. It is covered up under a plain steel caseback.
