Underground mining is one of the riskiest jobs in the universe. Not only is it dangerous for the ground to collapse and cover or bury miners inside a hole, but the continuous extractive work in a sunlight deprived area means the miner’s health is going to be highly affected. Moreover, radiations from rocks can be even life-threatening, causing complete gene mutation to the underground workers. What I want to share with you are the best watches for underground mining – the kind of watches approved for underground mining activities. We will also see how to pick a durable and a near indestructible miners watch.

Before the mine wars that turned the coalfields of southern West Virginia into a blood-soaked war zone, coal was the engine for the American prosperity. As many as 700,000 men were working up to 10 hours daily to provide coal that operated the steel mills.

Today, mining does more than just provide coal. Some mined minerals include diamond, gold, iron, copper and more. In turn, some of these mined substances are later used by the watchmaking industries to produce wrist watches. Which watches are approved for underground mining business?

Although underground mineral exploitation is a risky job, it nevertheless has safety rules that can prevent Miners getting trapped underground.

Topping the list of safety gears approved for  the people working for mining companies to extract mineral deposits, is a wrist watch. Just as a helmet is of great use to a miner to work effectively , a good under ground watch is a must-have wearable in a mining site.

Why an underground miner’s watch is different

Wearing a wrong wrist watch when extracting natural renounces from under the rocks is as dangerous as going without a timepiece into a deep cast mining ore. First, Watches with batteries can be potentially dangerous for gas mines.

An electric spark can cause an havoc if it ignites flammable ores or gaseous mines. Secondly, miners may lose track of time when they descend underground where to remove earth minerals and ores. Third, wearing an watch that is not designed to endure mining environments means it can easily get beaten and broken.

It is more challenging to work in extreme conditions inside underground caves and tunnels, underwater and physically remote and treacherous terrains. Despite this, miners operate heavy machinery and tools. Mining watches is as important as these mining tools.

It is important to note that an Underground mineral extraction job is more dangerous than surface mining and other industrial activities. So wearables, gears and other accessories for miners should be able to endure the harsh conditions in the underground mines. Thankfully, watches manufactured for miners comply with government and industry strict specifications to ensure a reliable durability.

A wristwatch serves as a tool for miners and one that is designed sturdy and rugged, wins the favor of serious underground miners. There are many qualities to consider when shopping for a good durable below ground watches. The same for miners above ground mining.


Tips on how to choose a miner’s watch

Underground is a unique and often unfamiliar environment with so much wrist of being buried there alive. People who work there may lose track of time if they have no wrist watch with them.

However, Miners sometimes regret picking the wrong watch when it easily gets broken from beatings from underground explorations.

With help of an underground mining expert, we have several tips that might guide you to selecting a durable, unbreakable and best underground mining watch for yourself. We also considered some mining safety rules in our guide


Watch movement

When working underground in a coal mine, a battery-powered watch may cause ignitions and flames which is intrinsically not safe for any there. So a watch with mechanical movement or any wrist watch that is intrinsically designed with safety in mind can be a better option for miners.
No miner would want to have a broken piece of the battery-powered watch in a coal or gaseous mine.


Anti-magnetic features

Magnetic fields negatively affects the accuracy of a mechanical watches. Metallic internal watch parts especially the balance spring, get magnetized when exposed to these fields.

Metalliferous mines can be extremely magnetic and filled with magnetic fields. Watches are made of metallic gears, case, disc, etc and these metals have a certain tendency to move when exposed to magnetic fields.

If the balance spring becomes magnetized, the watch oscillates faster, and run fast in timekeeping. This is a very big error in situations where precise timing is expected.

So mining Watches without anti-magnetic properties will immediately lose track of time and may eventually break or stop working. All underground miners should pick the best anti-magnetic watches.


Waterproof, mud and dustproof properties

A serious worker in a mine will make sure his watch is water-resistant, dustproof, dirtproof, and mudproof. If you have never been to an underground mine, then know that it is filled with mud, sometimes water, dust, and debris from rocks. Some mines are even acidic and there is a need to protect a wrist watch mechanism from being affected by these. Dust and waterproof sealed watches are the best options. If a miner intends to store the watch for a long time, a replaceable seal is one important accessory to take along.


The watch case

From resin material to plastic to stainless steel casing that protects the watch’s internal gears, not many of these case materials work perfectly for underground miners.

Stainless steel case miners watch is durable, corrosion-resistant, shiny, and does not wear out easily for long. Although metallic steel watches may be heavy on the wrist, and some steel may produce nickel allergies, they remain durable, tougher, harder even inside the mud.

Titanium made watches are also durable and constitute most favorite watches for people who do heavy lifting like construction, weightlifting and mining. The advantage here is that titanium watches are very lightweight on the wrist, yet the titanium case remains super hard like steel.

Carbon fiber cased watches are also durable. These timepieces are very lightweight, very strong, and unfortunately expensive.


Watch lume – backlighting in the dark

Underground environments are always in the dark and a suitable mining watch should glow brightly to allow visibility on the watch face.

Super-lumiNova, Lumibrite, and tritium tubes are some luminous pigments used in watchmaking but they don’t give the same luminescence. Some of them glow brightly, some are radioactive and dangerous, some are electrically powered. Whatever, is the intensity of the watch lume, make sure it glows and makes the watch dial to be more readable in the dark.

One thing to note is that most luminous watches automatically turn off the backlight after some number of seconds. However, for underground mining, the best luminous watches approved for mining must be able to remain illuminated for the entire working day, several hours in a single shift.

Watches with durable lume are even more helpful for people who get trapped down the mine or tunnel for several days, weeks or months.
The best luminous watch for miners is one with lume that can last several years to come.

The best recommendation is you should look for a watch that can keep the dial clearly visible and illuminated for several hours or days.


Other Underground physical conditions

There are also other physical conditions that a your mining watch should be able to withstand. The watch must resists, Vibrations, mud, dust, chemical attacks(acids, rusting, oxidation). They must also tolerate extreme temperatures in the range from -15°C to +50°C. Check out these watches with thermometer -temperature sensor


Precision or Accurate timekeeping

Precise timekeeping is highly expected for an underground watch or surface mining watch. To keep track of shifts and work schedules, serious miner’s particularly won’t want to have a timepiece that needs constant rewind in the midst of extractive activities.

This is where the calibre and the quality of the watch’s movement made by the watchmaker truly counts. Certified chronometer watches tells accurate time.

Besides, US Military standards, it is also known that the Contrôle Officiel Suisse des Chronomètres (COSC) is one of the bodies that checks a watch under a range of conditions, and certifies its accuracy.


The watch crystal

To keep a mining watch durable, unbeatable, and unbreakable, the dial of the timepiece must be covered by a tougher and more durable glass crystal. An underground watch with a dial covered glass that won’t easily get scratched or destroyed is the best choice.

Sapphire watch glass is been known in the watch industry as the strongest, toughest, and most durable crystal used to protect the watch dial window. This sapphire is used in the most expensive, high-end watches from luxury brands like Rolex, Tag Heuer and more others.

Sapphire is practically indestructible, unscratched and in addition to being anti-reflective, a sapphire watch is a nice timepiece to use in underground mining operations.


But how do you know a watch has sapphire crystal?

The story of a Coal miners Rolex Submariner

Valudable timepieces never lose their value for those who know it. In 2016, a Rolex Submariner with an ultra-rare 3-6-9 dial is said to have been sold for £227,000 at Gardiner Houlgate auctioneers.

David Hare, the director at Gardiner Houlgate describe this miners Rolex watch as “holy grail of vintage watches” which, he had expected it would sell for more than £200,000.

Amazingly at the time of auction, the watch was almost in its original condition. The experts called the dial a Crown-62’ variation which is even rare to find and even at that high price, the watches remain ought after by collectors worldwide. This particular watch has a version of the dial that experts call a ‘Crown-62’ variation, which is even rarer.

As to story goes, the Rolex Submariner 5512 was first bought by a medical attendant(the original owner) at a Nottinghamshire coal mine, for £70 in 1964. After 56 years, the vintage watch is still in its original condition. No scratch or any mark could be found in its bezel, glass or band. What surprises most people is that the Rolex vintage is still in its original package or box.

This watch was sold by the daughter of the original owner after the watch has been in the same family for over 50 years. Just imagine the financial support such a little but valuable(because the family discovered the possible value) wrist watch has brought to the family year of just seeing it as a watch.
