The Mechanical Dive Watch – Perfect for Field and EDC.

If you’re under 40 years old, the odds are that you don’t wear a watch, “I have a phone, what do I need a watch for?”. Well, if you never venture beyond your cubicle or apartment you’re right, you probably don’t need one. But, if you’re a hunter, you not only need a good watch, I’m going to suggest you buy a rugged dive watch with a good automatic mechanical movement of Swiss or Japenese design. Let’s take a look at your options for a quality Automatic Mechanical Dive watch for EDC and field use.

Watch Movements

First, we need to look at the movements. Movements are essentially the engine of the watch. There are two basic types of watch movements Quartz and Mechanical and they both have their merits.

Quartz Watch Movements

Quartz is one of the most common minerals on Earth. The interesting thing about quartz is that it’s piezoelectric. That means if you apply pressure to a quartz crystal, it generates a tiny electric current. Conversely, if you pass electricity through quartz, it will vibrate at a precise frequency.

Inside a quartz watch, the battery sends electricity to the quartz crystal. The quartz crystal oscillates (vibrates back and forth) at a precise frequency. The circuit counts the number of vibrations and uses them to generate regular electric pulses, one per second. These pulses drive a small electric motor that turns gear wheels that spin the clock’s second, minute, and hour hands.

There’s a couple of big benefits to quartz movements:

  • Accuracy. Watches with quartz movements are among the most accurate that you can find. A $200 quartz watch will actually keep better time than a $5,000 automatic movement watch.
  • Cost. Quality Quartz watches usually will cost significantly less than a similar watch with an automatic mechanical movement.

Quartz watches also have a couple of drawbacks.

  • Batteries die at inopportune times. I can remember several occasions where my watch battery died when I’ve been on a trip.
  • The only way to replace the battery is to open the case and break the watertight seal. Most places that replace watch batteries do not properly reseal and pressure test.
  • Quartz watches do not typically have the longevity that mechanical watches enjoy.

Mechanical Watch Movements

The Mechanical movement preceded quartz technology by close to one thousand years. Unlike quartz or digital watches, which require a battery to run, mechanical movements harness the energy stored in a wound mainspring. There are two types of mechanical watches, manual and automatic. A manual mechanical watch requires the wearer to wind the watch on a daily basis. In automatic watches, there is a flat blade positioned in the back of the movement that swings back and forth as the wearer naturally moves his or her wrist throughout the day. As that blade swings and spins around it winds the mainspring of the watch.

Benefits of an automatic mechanical movement:

  • Longevity. An automatic mechanical watch will stay wound as long as you wear it, and can keep working with minimal maintenance for decades. You can pass down a high-quality mechanical watch for generations
  • You’ll never have to replace the batteries.

Mechanical watches also have a couple of drawbacks.

  • Initial Cost. Automatic mechanical watches use expensive materials and require highly skilled labor to manufacture. That makes them more expensive than your typical quartz watch.
  • Maintenance. Automatic watches are not completely maintenance free. When they do require maintenance you typically have to send them to the factory for a tune-up than that can run a few hundred dollars.

Why a dive watch?

Even though occasional snorkeling is as close as I come to diving, I have a strong preference for the dive watch style for a few reasons:

  • They’re tough. Dive watches are built to withstand the high pressure of deep dives. This translates to a really rugged design.
  • A common feature of the dive watch style is the rotating bezel that is usually marked in minute increments. It’s easier and faster to spin the bezel around to use as a timer than pulling out my phone.
  • I personally like the look, and their larger case size is a better fit for my wrist.
  • Luminescence. If I hit my watch face with a flashlight before I leave camp, I can read the time until first light without having to pull out my phone and light up the woods.
