The EZM 12 (Einsatzzeitmesser 12) is a wristwatch from Sinn.

This model was developed specifically for air rescue services.

Technical features include:

• Upward-counting inner bezel for quick reading of the “Platinum Ten Minutes” and the “Golden Hour”
• Downward-counting outer bezel with a black hard-coating on a tegimented base
• Pulse Rotor with Pulse Rotor scale for determining heart rate
• Special design of the strap system and rotating bezel, allowing for easy cleaning and disinfection
• Ar dry-seal technology, ensuring enhanced reliability and resistance to fogging
• Magnetic field protection up to 100 mT (=80,000 A/m)
• Temperature-resistant technology, ensuring reliable operation from minus 45°C to plus 80°C

Every rescue mission by emergency medical personnel is a fight for human lives—and against the clock. After all, the “Platinum Ten Minutes” and the “Golden Hour” dictate the course of action. This means a patient should arrive at a hospital no later than one hour after the accident. A critically ill patient should even be treated and transported within 10 minutes.

For this life-saving mission, Sinn has developed the EZM 12 emergency timer. With the upward-counting inner rotating bezel, emergency medical personnel can keep the aforementioned time categories in view at all times. The downward-counting outer rotating bezel can be used, for example, to monitor medication administration times. The integrated pulse scale— in combination with the rotor-shaped second hand—allows for quick determination of heart rate in 15-second intervals. With the EZM 12, emergency responders have a powerful tool that can make a significant contribution to saving lives.

The watch was honored with the “Excellent Product Design 2020” award at the German Design Award and with the Red Dot Product Design Award 2019.
