EZM 1 - Der Einsatz-ZeitMesser 1 - The "Mission Timer 1" & Measure Time for operation

 

The Sinn 503 EZM1 (Einsatz Zeit Messer) was specifically designed for the elite German Grenzschutzgruppe (GSG-9) Federal German Border Commandos. The watch is also utilized by the specialized Zentralunterschtutzunsgruppe (ZUZ) Unit.
The GSG-9 was formed after the terrorist attack at the Munich Olympics in 1972. Since that time, the elite unit has been called out to handle many terrorist incidents including the hijacking of a Lufthansa jet by the an offshoot of the infamous Bader Meinhof terrorist group. The EZM watch was designed for functionality under the harshest of conditions, and is actually worn by members of elite units.
The EZM1 has a number of very unique features:
Readability was important, all other aspects were irrelevant. This is why the date function of the EZM is very discretely placed at the "4" o'clock position, it is very small and printed in red.
All other printing on the dial is also done in red, so not to distract from the readability. The elapsed chrono minutes can be read very quickly because the minute pointer is placed central of the dial. The chronograph function can show a maximum elapsed time 1 hour. There are no sub-dials showing the elapsed hours. This would only distract from readability.
This is a typical feature of the Lemania 5100 movement, and this is also one of the main reasons why this movement is so popular with the military watch enthusiasts.
The bezel is bi-directional, like on most watches, the elapsed time, but it is used here as a count-down timer. You can quickly synchronise the normal-time minute hand with the number of minutes you want to count down from, once the normal-time minute reaches the triangel or "0" on the bezel, that number of pre-installed minutes have passed.
A special manufacturing process is utilized, and the entire case is filled with argon gas. The argon gas helps to eliminate any ambient moisture that may be present in the manufacturing environment. The gas also minimizes surface corrosion and helps to keep lubricants from breaking down over time. The gas can prolong the time between service intervals. This exclusive system eliminates condensation under temperature extremes.
Good night visibility is also important on this type of watches. With specific regards to the luminosity of the dials, as of ~2002, the "3H" logo has been replaced by an "Ar" logo (i.e Argon gas filled watch). The hands and dial no longer contain tritium (3H), having been replaced by Luminova (Strontium Aluminate).It is recommended for tactical operations or for any use where a tough and accurate watch are called for.
The Sinn EZM1 is no exception to this as it a watch that exuded German practicality, precise engineering and precision.
History of the Lemania 5100
The chronograph world isn’t what it used to be. Due to escalating manufacturing cost, the Swiss industry has gravitated toward fewer popular calibres. An example of one such basic and functional calibre is the Lemania 5100. Manufactured since 1978, it was once rescued from an untimely demise by the Swatch group and then put to death again by a policy change in the same hands of the rescuer.
In the 1997, Nouvelle Lemania was planning to cease production of the 5100, a particularly rugged but accurate calibre used mostly in military and space applications.
The 5100, due to its construction, is the only chronograph movement that can withstand large shocks without its chronograph seconds hand stopping. This is because its chronograph mechanism is driven directly unlike most other chronographs which use an intermediate wheel. The calibre easily withstands acceleration in excess of 7G without appreciable loss of accuracy. Its ruggedness is legendary; the calibre easily absorbs shocks and blows. The calibre also maintains its accuracy over long periods without servicing. Service intervals from four to seven years have shown to be sufficient.
The lemania 5100 chronograph caliber was discontinued in late 2003 / early 2004.
This is choice for the spec-ops, Navy Seal, UDT, SAS and Australian Divers. Approximately over 20 years, these watches earned them the right to be used by armies such as Czech, Polish, French Navy , German Federal, some Nordic countries, SAS and Australian Divers and also by the US Navy ( SEAL , underwater demolition team , frogman).
