he new EZM 1.1 S model, celebrating the 25 years of Sinn’s mission timers, has everything it takes to stand its ground even under the most adverse conditions. The German brand has equipped it with the technology necessary for the most demanding of missions: such as Ar-Dehumidifying Technology for greater functional reliability and freedom from fogging and Temperature Resistance Technology for reliable function in temperatures of –45°C to +80°C.

The bead-blasted surface of the stainless-steel case has also been hardened using Tegiment Technology, which forms the basis for the Black Hard Coating. This gives the chronograph a high-quality, modern and professional feel. This combination is the most durable form of black coating that is feasible according to the latest advancements in technology.

To complete its core mission of unhindered and accurate time measurement, the EZM 1.1 S must have taker qualities and be able to function with instrument-like precision. The top priority is the need for outstanding readability at a glance – a prerequisite in time-critical situations – and even under the most adverse conditions.

The EZM 1.1 S therefore features the chronograph movement SZ01. Based on the tried-and-tested Concepto C99001, the SZ01 is designed in such a way that the watch has a jump 60-minute stop hand from the dial centre. This enables stop times to be recorded more easily, quickly and accurately. Firstly, 60 rather than 30 minutes are counted in one sweep of the hand. Secondly, the minute stop scale covers the entire diameter of the dial.

Another useful instrument for recording cumulative time, besides the chronograph function, is the captive countdown pilot’s bezel with minute ratcheting, which can be rotated on both sides. Its captive design makes it virtually impossible for it to become detached from the case. In the interest of readability and timekeeping, all markings on the dial not relevant to the mission are muted in red. The crown and push-piece are also carefully positioned on the left side of the case to prevent pressure on the back of the hand and keep the watch from getting caught, even in time-critical situations.

Created for optimal readability, the design of the EZM 1.1 S stands on the shoulders of tried-and-tested models. This chronograph is actually a special limited edition (500 pieces) to mark the 25th anniversary of Sinn’s mission timers. It all started in 1997 with the now legendary EZM 1 – a chronograph that set benchmarks in terms of functionality and clarity.

Unsurprisingly really, considering it was designed for professional users who have to rely implicitly on their watch because the success of the mission and sometimes even human lives depend on it. Professional users such as the German Central Customs Support Group, ZUZ (Zentrale Unterstützungsgruppe Zoll), a special unit assigned to the German Customs Investigation Bureau – much like a special police commando unit.

This founding watch created the design DNA for all subsequent mission timers: the design should be based exclusively on its intended function, i.e. form follows function. Whether pilots, divers, firefighters, emergency doctors, rescue workers, special units of the German police force such as the GSG 9 and Germany’s commando frogman force KSM (Kommando Spezialkräfte der Marine), each mission timer is designed precisely according to this principle, based on individual requirements.

The key is in working with the experts – in other words, with those who actually use the watches. Especially since the conditions in which Sinn’s mission timers have to prove themselves are as varied as they are challenging: including wetness, magnetism, extreme heat and cold, major changes in temperature, vibrations, impact and knocks as well as aggressive liquids such as salt water or disinfectant. And often, everything at once. Basically, mission timers have to withstand a great deal – especially when the going gets tough.

Since each mission timer is equipped with the relevant functions for the operation’s specific requirements, no two are the same. Yet they are united by one common principle of construction and design: focus on the key essentials in terms of outstanding readability and rapid time recording. Incidentally, these are virtues that also please watch lovers who do not necessarily have to cope with life-threatening missions in their everyday lives. People who appreciate the fact that a watch like the EZM 1.1 S is an accurate, reliable and extremely robust timepiece.
