5 Best Underground Mining Watches


Mining is one of the most challenging industrial sectors. The workers employed in mining have to undergo most extreme conditions like working in underground caves and tunnels, underwater and other treacherous terrains. Moreover, miners have to work regularly with heavy machinery and enormous tools. Mining watches are so important.

Working in a mining site is entirely different from the other industrial activities. So the clothing and other accessories typically worn by miners should be able to withstand the harsh conditions in the underground mines. Generally, such products are manufactured by following strict specifications to ensure excellent durability. These standard specifications are applicable to wristwatches also. A wristwatch is a necessary tool for miners. You will find a lot of sturdy and rugged watches in the market but not all of them are suitable for underground miners.

Desirable Features of an Underground Miner’s Watch

A miner’s job demands lots of physical work and the timepiece he wears should be sturdy enough to protect it from physical damages. Therefore watches made with durable materials like stainless steel and titanium are more preferred in this sector. The glass should be made from sapphire crystal, which is exceptionally scratch-proof. The watches with excellent shockproof features are more ideal to avoid damages while working with large scale machinery and tools. 

Frequent exposure to magnetic fields can adversely affect the accuracy of a mechanical timepiece. In the mining sector, you will come across several types of machinery with intense magnetic fields. If your timepiece is anti-magnetic, it can naturally resist such potential interferences. In some Mining sectors, quartz watches are not allowed due to potential fire hazards. Hand-wound movements are also inadvisable as it is difficult to wind them frequently, especially if you are wearing gloves or any other protective gear. So a perfect watch for underground miners should be equipped with an automatic (self-winding) mechanical calibre with excellent anti-magnetic and shock-proof features. The wearer’s hand movements are enough to keep the automatic watch energized for long periods.

While working in the mines, the wristwatches can come in direct contact with dirty water, mud or oil. So a Miner’s watch should have outstanding water resistance and dust/mud resistant features. The timepiece should be easily washable so that its user can properly clean it without much hard work. Metal bracelet, rubber and silicone strap are generally water-resistant and they can be easily cleaned. 

Leather straps are not advisable for miner’s watches. The dial readability is an important aspect when you work in areas with less light. So, always get a piece with the simplest dial details and the best luminous technology. Bulky watches are undesirable as they are vulnerable to physical damages.

Keeping the above specifications in mind, we have shortlisted five most suitable wristwatches for underground miners:

1. Omega Seamaster Aqua Terra > 15,000 gauss
