A military watch should always be a part of your tactical gear such as a tactical knife. It is one of the most multifunctional timekeeping devices. Not only does it keep an accurate record of the time, but a military watch also offers you loads of other features that are essential to your survival in the untamed wilderness, forest, and urban jungle.
How to Choose the Best Military Watch
Types of Watches
Military watches come in 3 types. Field watches, such as the Isobrite ISO100 Ultra Bright Dive/Tactical T100 Tritium Watch, have basic features and are ideal for general law enforcement or military use.
A navigator watch, such as the Casio G-Shock Rangerman GW-9400 Military Watch, has high-tech features that suit specialized tactical operations. Diving watches, such as the Marathon, Invicta, or Luminox watches, are designed for marine professionals.
Durability
A military watch should have water-resistant stainless steel or tough resin case and a bracelet or strap with a securely closing clasp, buckle, or button. The display window should be made from a shockproof and scratch-resistant material. Mineral glass is a good material but sapphire glass crystal is considered to be a highly superior material.
Analog or Digital Display
While many military watches have either an analog or digital display, some watches offer you both such as the Casio GA100-1A1 Military Watch.
Standard and Military time
A military watch may display the time in a standard 12-hour format or offer standard 12-hour and military 24-hour time modes.
World Clock
Having a world clock on your military watch is a great feature. Wherever you go in the world, you will have instant access to accurate global time at just the press of a button.
Compass
A compass is a vital tool for hiking in the wilderness, engaging in tactical desert operations, or search and rescue sea missions. It can help you to navigate your journey until you reach base camp or dry land.
Chronograph
The chronograph, or stopwatch, is usually displayed with 1 or 3 dials that have seconds, minutes, and hours. You can use the chronograph to calculate speed and distance.
Altimeter
An altimeter provides elevation data so that you can accurately monitor ascent and descent throughout your climb.
Barometer and Thermometer
A barometer can be used to predict weather changes by showing short-term trends in air pressure. A thermometer accurately records temperature shifts and is especially important in snowy terrain or in areas that experience rapidly changing weather patterns.
GPS
GPS provides a high level of on-demand satellite accuracy when compared to using a compass. However, if you do struggle to get a signal on your watch, especially at sea, you can default back to the compass to get safely back to civilization.
Smartphone Capabilities
Some high-tech military watches allow you to receive e-mails and texts. One of the downsides of using a smart tech watch is that you may have to calibrate the watch or download updates from the manufacturer’s website to keep the watch functioning properly.
Movement Mechanism
Military watches that utilize an internal mechanism such as a Swiss Ronda or Japanese quartz movement are known as the most precise and accurate timekeeping movements.
While there may be some hand-wound watches around, most military watches have an automatic or “self-winding”, movement that generates energy from the natural movement of your arm. If you stop wearing the watch for some time, you will have to wind it again.
Battery Type
Some watches may use a rechargeable lithium battery that can last up to 2 years, an extra powerful lithium battery Button cell that lasts up to 10 years such as the Isobrite ISO100 Ultra Bright Dive/Tactical T100 Tritium Watch.
Other watches, such as the Casio G-Shock Rangerman GW-9400 Military Watch, have a built-in solar battery which eliminates the nuisance of replacing batteries or resetting the time. Users never have to reset the time.
Screen Illumination
Backlit screens and illuminated hands and hours allow you to quickly read the screen at night time. If the screen is too bright, it may not be ideal for covert operations where you need to be invisible to the enemy.
