The 10-4
Product Details
Black zirconium is a metal prized for its natural toughness and featherlight feel — far lighter than tungsten while still standing up to demanding, active shifts. The dark charcoal gray surface is created by heat-oxidizing the metal itself, so the color isn't a plating or coating that can chip or peel over time.
The engraved channels are precision-cut and then filled with Cerakote, the same ultra-durable polymer-ceramic coating used on firearms and tactical gear. This locks vivid color into the design while resisting scratches, chemicals, and the kind of punishment that comes with a life on the job.
The 10-4 takes its name from the ten-code for message received — and the engraved motifs speak directly to those who carry the badge every day. Signals, symbols, and the language of the radio are worked into a ring that says everything without saying a word.
The comfort fit interior features a smooth, gently domed profile that reduces contact with the skin along the inner edges of the band. Whether you're pulling a double or finally off the clock, that rounded inside makes a real difference in how the ring feels after hours of continuous wear.
Clean The 10-4 with warm water and a mild soap using a soft cloth — avoid abrasive scrubbers that could dull the engraved Cerakote fill. The black zirconium body is scratch resistant, but deep scratches or scuffs will show zirconium's natural silver tone underneath. If the ring is exposed to harsh solvents or cleaners on the job, a quick rinse afterward will keep the finish looking sharp.
Getting the right fit is especially important with a comfort fit band since the rounded interior can feel slightly different than a standard fit ring of the same size. Take a few minutes to measure properly before you order — find your size.

The honest answers
Black zirconium is one of the toughest materials in the ring game — it resists scratches, nicks, and everyday abuse far better than softer metals like gold or silver. The dark charcoal finish is created by oxidizing the zirconium itself, so it's part of the metal, not a surface coating that can peel or chip off over time.
Yes — the precision cut engravings filled with Cerakote are crisp and bold in person, with strong contrast against the dark zirconium base. If anything, customers tell us the details read even cleaner on the wrist than they do on screen.
Black zirconium is widely considered hypoallergenic, making it a strong choice for anyone with sensitivities to nickel or other common alloys. It contains no nickel, cobalt, or chromium, so most people with metal allergies wear it without any irritation.
The inside of The 10-4 is smooth and gently rounded toward the edges, so there are no sharp corners pressing against your finger during a long shift. Most wearers stop noticing it's there within the first hour — which is exactly the point.
Cerakote is a polymer ceramic coating originally developed for firearms — it's extremely durable, resistant to heat, chemicals, and abrasion. Here it's applied into precision cut engravings, so the design is recessed and protected, not sitting exposed on the surface where it would take constant wear.
A quick rinse with warm water and a soft cloth is all this ring needs for routine cleaning — avoid harsh chemicals, bleach, or abrasive cleaners that could affect the Cerakote fill. Dry it thoroughly after washing, especially if you're working in wet environments, and it'll stay sharp-looking for years.
The comfort fit interior gives a little extra room at the edges compared to a flat-fit ring, which helps during minor swelling from heat, exertion, or long hours on duty. For significant swelling concerns, make sure you measure your finger at different times of day to get a reading that reflects your finger's natural range.
Getting sized accurately before ordering makes all the difference — ring size can fluctuate with temperature, time of day, and activity level. We suggest using our Manly Ring Sizer to land on the right fit: Find your size.
