Radiation Detector

Measures gamma-radiation with a Geiger-Muller tube, which digitally illustrates Dose Equivalents (DE) and Dose Equivalent Rates (DER).


Digital Display

Electroluminescent digital display illustrates the current time in minute/second format, the date in day/month format, the year and daily alarm in hour/minute format.


Sapphire Crystal (Glass)

Multiple ultraviolet anti-reflective coated layers and a scratch-resistant sapphire glass crystal.


Case & Bands

Solid titanium watch case with your choice of black DLC plating, a sandblasted gray or brushed stainless steel finish.


Glowing Dial & Hands

Specifically designed for easy reading in harsh conditions with tritium gas filled tubes that glow brightly and continuously for 25 years without any external light source. Approved by the US NRC.


The MTM Special Ops RAD is a tactical watch for men that measures harmful ionizing radiation through a Geiger-Müller tube. It is a geiger counter watch that measures single-dose gamma ray levels, as well as cumulative exposure over time. The ultra-sensitive radiation detector within the watch measures and tracks dose equivalents of Gamma Radiation – from 0.0001 to 9999 millisieverts (mSv), and the dose equivalent rate of up to 4000 microsieverts per hour (μSv/h). Users can preset their maximum radiation threshold, up to 9999 mSv, and an alarm will sound when the level has been reached. Radiation levels are displayed graphically and can also be shown on the digital display, which can be switched between dose equivalent rate, accumulated dose, and the time. The time is shown via tritium illuminated analog hour, minute and second hands. The digital display is EL backlit. The MTM RAD is water resistant up to 330 feet and powered by a lithium battery. The watch case is solid titanium with a brushed stainless steel finish. The MTM RAD is a unique technical instrument with a limited edition total of 1500 pieces. The RAD watch is a must have for all radiological technologists, technicians, and professionals and for those familiar with radiology terminology and its implications.


The RAD is also supplied with an IR Adapter and flash drive software, which enables data transfer from an MTM RAD watch to your computer. (Not compatible with Mac computers and Windows 10)


NOTE: The MTM RAD is a serious instrument designed for radiation-related professionals and radiologic technologists. Due to its intended technical purpose and critical readings, the RAD is not necessarily intended for the casual user. The RAD instruction manual is written with the radiation professional in mind. The casual user or watch collector may have detailed in-depth questions as to how to use the RAD watch properly. An explanation of those basic questions is included in the RAD’s operating manual. However, further technical questions regarding data or its interpretation will not be addressed by MTM customer service personnel should they arise by the casual user.
