The Right Materials Make a Watch Tough Enough for Anything

When you build a watch meant to be worn every day, durability is more than a feature, it's a philosophy. That philosophy is central to VERO Watch Company. Every material choice, from the crystal to the movement, to the colorfully coated cases is selected with long-term wear and honest aging in mind.

We’ve gotten some great questions over the years about each key component of our watches. Here is an overview with some interesting facts peppered in. 

Sapphire Crystal: Built to Resist Time (and Scratches)

One of the most noticeable upgrades in a well-built watch is the crystal. A sapphire crystal is the most durable watch crystals on the market and have changed the game when it comes to lengthening the lifespan of a good field watch.

On the Mohs hardness scale, which ranks materials from 1 (talc) to 10 (diamond), sapphire sits at a 9. Only a diamond ranks above it in hardness. This makes a sapphire crystal exceptionally durable for daily wear. It’s significantly harder than mineral glass (typically around 5–6), and it resists impact and scratches from daily wear around the home or office, or out on the trail.

Synthetic sapphire used in watches is chemically identical to natural sapphire gemstones. It’s grown in controlled environments to ensure optical purity and structural consistency. Our sapphire crystals also come with an internal AR (anti-reflective) coating, which keeps your watch legible in bright, direct sunlight.

Stainless Steel: Strength with Staying Power

Most VERO cases are crafted from 316L stainless steel, often referred to as “marine grade” steel. It’s highly resistant to sweat, humidity, and saltwater exposure, making it ideal for daily wear across varying climates. It also has a natural ability to be refinished, meaning light surface wear can often be restored.

For watches, another benefit is that it’s easy to finish in different ways. You’ll see brushed surfaces, polished surfaces, or a mix of both. Over time the case will pick up small marks, but stainless steel can often be refinished to clean those up.

Bronze Watch Cases: Controlled Oxidation as a Protective Layer

Bronze cases are typically made from copper-based alloys such as copper-tin bronze, or aluminum bronze. Though brass and bronze are both copper-based alloys, they differ in composition and properties. Brass is comprised of copper and zinc, while bronze is primarily copper and tin, which gives the material that warm brown tone over time. 

Unlike the steady appearance of stainless steel, the bronze watch cases of the Smokey 80th Edition watches have a “living patina” that evolves with wear. This patina acts as a protective barrier, slowing deeper corrosion, and will eventually develop a rich, warm tone. The watch case changes in appearance over time due to exposure to humidity, salinity, and the oils in our skin. This makes the Smokey 80th Edition watches unique in that each watch will visibly tell the story of it’s adventures on your wrist.

Some of VERO's watches have a deep black finish created with something called DLC coating, which stands for Diamond-Like Carbon. The result is a dense, matte black, protective layer over the stainless steel components of our watches, as seen on the VERO SW-Q Sports watches, as well as our Limited Edition Hooligan Nightfall, and our latest release, the VERO X Realtree Tide Tracker in Midnight Black. 

This coating is applied in a vacuum chamber using a process called physical vapor deposition. A super thin layer of carbon bonds to the surface of the metal and creates an extremely hard outer layer.

The structure of the coating is partly similar to diamond at the atomic level, which is where the name comes from. The result is a finish that’s much more scratch resistant than bare steel and has a really clean matte black appearance. DLC coatings are also used in things like automotive engine parts and aerospace components where durability is important.

Cerakote (Ceramic Coating): Thin-Film Ceramic Polymer Protection

Another protective coating you’ll sometimes see on VERO watch cases is Cerakote.

Cerakote is a ceramic-based coating that’s sprayed onto metal and then cured in an oven. It was originally developed for firearms and industrial parts that need protection from corrosion and wear.

Once applied, it forms a thin protective layer over the metal. It’s not quite as hard as DLC coating, but it does a great job protecting against corrosion, scratches and abrasions, and environmental damage. It also allows for a wide range of colors and matte textures, like on the VERO Forest Service Edition watches, and the recent VERO X Scout Motors Limited Edition Workhorse Chrono’s.

IP (Ion Plating) Coating

Ion plating (IP) is a process used to give stainless steel a tough, long-lasting outer layer. The VERO Smokey Campfire Edition watches have a gunmetal IP Coating that mirrors the rich gray shade of its dial. Not only does it add an overall darker aesthetic to the watch, the IP coating also acts as added protection against the elements.

Each case is placed in a sealed vacuum chamber where a metal (often titanium) is heated into a vapor and turned into tiny charged particles. These particles are drawn to the watch case and bond tightly to its surface, building up a very thin but durable layer. Unlike regular coatings that sit just on the surface, this one fuses at a microscopic level, making it much more resistant to scratches, wear, and fading while also giving the watch its distinct dark finish.

When a watch is meant to go beyond the office, the materials start to matter a lot more. Scratches, sweat, weather, bumps against rocks or gear… all of that adds up.

We make modern field watches built with materials known for durability in the real world. Each component plays a different role- some resist scratches and knicks, some fight corrosion, and others are built to keep running reliably for years.

Put together, they create watches that are ready for whatever the day turns into—planned or not.
