Introduction: 6 Wrist Watch Survival Hacks
No one sets out to get lost, but when it happens you need to make the most of what you have on hand...or on your wrist.
Though the humble wristwatch is something that many of us might take for granted, did you know that there's a few tricks up your sleeve with this tiny timepiece? For example, there's ways to start a fire, tell direction, and even a way to make an emergency blade...all from an unassuming wristwatch!
Follow along as we explore several uses to help you survive in the wild with your wristwatch.
Step 1: Tell Direction
Before dismantling your watch, you can actually use it as a simple compass to help tell direction. This trick will require any analog clock or watch and be preformed during daylight hours.
The process is slightly different depending on which hemisphere you're in, but both follow the same steps:
Lay the watch flat on your hand with the clock facing upwards, then rotate the entire watch until the hour hand is pointing in the direction of the sun. The point midway between the hour hand and the 12 on the watch will be South.
Lay the watch flat on your hand with the clock facing upwards, then rotate the entire watch until the 12 hand is pointing in the direction of the sun. The point midway between the hour hand and the 12 on the watch will be North.
From here you can determine the rest of the compass directions.
Step 2: Dismantle Watch
Watches contain loads of smaller components that can be used in a variety of survival situations.
Most watches are easily opened up from the back. Look around the back plate for a small notch that can be used to pry off the backing with a sharp knife. Be careful here, as the watch back is fitted very tightly.
With the back of the watch removed, the remaining components can be easily removed from the watch housing. The glass front of the watch is also pressure fit in place, and can be carefully knocked out of the metal housing with a blunt stick, or rock wrapped in cloth.
Step 3: Start a Fire
Many watches use a convex lens as the glass cover over the watch face, this makes reading the time easier. The lens is perfect for focusing the sun to start a fire.
Wipe the lens clean of any smudges and hold it about 6 inches from your dry tinder. You'll want to hold the lens perpendicular to the sunlight and move the lens to focus the sun into a point of light. Move this point to the tinder and hold for a few seconds, the intense focused beam of light is incredibly hot and should easily ignite your tinder and start your fire.
Step 4: Primitive Sundial
It might seem silly to make a sundial from a watch, but if you're stranded and your watch runs out of batteries then this is a pretty good use.
Though sundials might seem primitive, they are actually carefully designed based on where they are manufactured as the sun casts different shadows based on where you are located latitudinally. To compensate for shadow length the arm that extends out from the dial plate and casts the shadow is set at different angles, this arm is called the gnomon. To tell correct time the gnomon needs to be parallel with the earth's axis and should point towards True North (see the step about using your watch as a compass).
It would help if you knew your approximate latitude before you set out, this will be the approximate degree that your gnomon should be set at. For example, if you're camping somewhere in Northern California you could approximate your latitude as 40º, therefore your gnomon angle for your sundial should be 40º.
Obviously this isn't going to give you precise time, but can help you keep track of the day while you are stranded. Start by aligning the sundial to the 12 when the sun is at its highest above you. By spending more time with your sundial you can refine it slightly to get more accurate time. Knowing that the sun travels 15º westwards in one hour you can easily start marking hours and minutes.
Step 5: Reflector
The solid back of watches are perfect reflectors to get attention of people far away, or passing aircraft.
Even if your watch back has a matte finish, it can likely still be used as a reflector. Try buffing the watch back with any cotton cloth to really shine it up, then point the watch back facing the sun and try and reflect the sunlight. Practice directing sunlight to somewhere nearby first to dial in your reflecting technique.
When you're ready, you can easily signal people very far away by flashing the reflector towards them to get their attention. If you're feeling really confident, you can even flash out Morse code and send a message!
Step 6: Hone a Knife
Many watches have a leather strap which not only makes for a comfortable fit, but also gives us a great material to make survival things from.
The leather strap can be used just like a strop to hone a blade. Fasten one end of the watch strap to secure it, then gently run the edge of your knife along the leather strap with the sharp edge trailing the stoke. Though the strap might be small, it'll still work to remove any burrs on the knife edge and bring back an edge to your knife.
Step 7: Make a Blade
If you're a savvy in the outdoors, you probably already have a knife. But, in a survival situation you might need another blade for different uses: perhaps you want to preserve your good knife for things that need a refined and sharp edge, or maybe you lost your knife.
In survival situations you can use your watch to create a blade. Covering the glass front of the watch with a leaf, gently tap on the glass to fracture and create glass shards. You'll easily find a few pieces that are super sharp and can easily be made into a blade.
Use your glass shard to cut a long continuous strip of leather from your watch strap, this will be used to lash the glass shard to a handle. To make a handle find a a sturdy stick with an opening on one end, then insert the glass shard to it's seated securely in the opening and lash it tight with the leather strip.
While it's certainly not as sturdy as a real knife, this blade can easily cut fabric and flesh.
