20 years of mission timers

An accurate timekeeping tool

EZM 12
The EZM 12 is the latest member of our family of mission timers. Designed as a tool for emergency service doctors, the EZM 12 enables optimum readability and measurement of critical times. The reasoning behind this is that critical decisions are made and life-saving measures performed upon arriving at the scene of an accident.


Since the company’s foundation in 1961, we have focused on making navigation cockpit clocks and wristwatches designed to ensure maximum functionality and precision. Careful consideration goes into all of our timepieces, as functionality is always at the forefront of every concept and design. For the last 20 years, this philosophy has been implemented to perfection in our mission timers.

The EZM 1, which in 1997 was the first mission timer we developed for the special units of the German police department and customs authority, marked the dawn of an impressive era. As reliable, robust and accurate as an instrument, our mission timer is now available for a whole host of professional users, always specially developed to meet the requirements of the application. These include pilots, divers, firefighters, emergency doctors, rescue workers, special units of the German police department and armed forces such as the GSG 9, Germany’s commando frogman force KSM (Kommando Spezialkräfte der Marine), and the special unit of the German Central Customs Support Group ZUZ (Zentrale Unterstützungsgruppe Zoll). Despite all their differences, these users all have one thing in common: they rely on the exceptional performance of our watches on a daily basis – particularly in critical situations.
