Hazard 4 Titanium Bracelet for Heavy Water Diver Watch

***Estimated Lead Time: 3-4 weeks

*Due to the nature of this product, returns/exchanges cannot be accepted”

The Hazard 4 Titanium Bracelet is a Grade 2 titanium watch band custom-designed for the Heavy Water Diver tritium watch, fitting 24mm lugs and weighing just 3.2 oz at its longest configuration. That figure is roughly half the weight of a comparable steel bracelet for a 50mm watch, and the Grade 2 titanium construction is 100% hypoallergenic — eliminating the skin irritation common with stainless steel on extended wear. Available in Black and Silver, the bracelet ships in a presentation box with pillow, bracelet retainers, and removable pin covers stored in a flask insert.

Who this is for

  • Heavy Water Diver owners who want a purpose-matched metal bracelet that complements the watch's 50mm case without adding the mass of a steel option.
  • Active and water-sport wearers who need a hypoallergenic, corrosion-resistant band suitable for diving, salt water, and daily sweat exposure.
  • Detail-oriented collectors who appreciate reversible titanium pin-cover tubes, user-laser-engravable links, and a deployant clasp with a 3-position micro-adjust.

Compatibility with the Heavy Water Diver

The bracelet attaches via custom Hazard 4 clover-pins designed specifically for the Heavy Water Diver's 24mm lug spacing. Watch pins are sold separately; installation requires a Torx 6 screwdriver or bit, not included. Blue Loctite solution is included and must be applied to the screws during installation to maintain secure long-term assembly. Follow the included installation instructions precisely — the Hazard 4 Heavy Water Diver Changing Strap Instructions document covers the full procedure.

Link design and fit system

The curved-H link profile distributes flex across the natural contours of the wrist rather than pivoting at a single flat plane, which keeps the bracelet seated flush against varied wrist shapes. Three removable hairpin links on each side of the deployant clasp allow wrist-size adjustment across a wide range of wearers. The deployant clasp itself adds a further 3-position micro-adjustment for fine-tuning fit between link increments. Side-release buttons and a thumb safety bar on the clasp provide confident, snag-free operation.

Materials and personalization

The main bracelet body is Grade 2 titanium. The deployant clasp uses steel construction for fatigue resilience under the repeated open-close cycle of daily wear. All machined edges are slightly rounded to remove sharpness without producing a visually soft or over-polished appearance. The removable pin-cover tubes between the lugs are marked "TITANIUM" on one face and blank on the reverse, so the wearer chooses which face shows. The tubes accept user-applied laser engraving and can be coated or anodized in accent colors. The clasp carries an etched Hazard 4 logo on its face and the word "TITANIUM" on the underside.

Frequently asked questions

Does this bracelet fit any watch other than the Heavy Water Diver?

It depends. The bracelet uses a 24mm lug width, so any watch with 24mm lug spacing and compatible spring-bar geometry can accept it physically. One reviewer fitted it to an Apple Watch Ultra 2 using 24mm adapters. The clover-pin attachment system is custom to the Heavy Water Diver, so direct pin-to-lug installation works natively only on that watch. For other watches, compatible adapters may be required.

What tools do I need to install this bracelet?

A Torx 6 screwdriver or bit is required to seat and secure the screws. The tool is not included. Blue Loctite solution is included in the packaging and must be applied to the screws during assembly. The Hazard 4 Heavy Water Diver Changing Strap Instructions document covers the full installation procedure step by step.

Can I shorten the bracelet myself?

Yes. Three removable hairpin links on each side of the clasp handle most wrist-size adjustments. For wrists smaller than the minimum link configuration, a watch repair shop can remove additional links — one reviewer did exactly that without issue. The 3-position micro-adjust on the deployant clasp handles fine incremental fitting between link steps.

Is the bracelet safe for water and skin contact?

Yes. Grade 2 titanium is 100% hypoallergenic and highly corrosion-resistant, making it suitable for prolonged skin contact, sweat, and salt-water exposure. The deployant clasp is steel, which carries more corrosion risk in persistent salt-water conditions, but it handles the open-close fatigue cycle better than titanium in that application.

Can I personalize the pin-cover tubes?

Yes. The removable pin-cover tubes between the 24mm lugs can be reversed to show a blank face instead of the "TITANIUM" marking, laser engraved by the user, and coated or anodized in accent colors. Changing the tubes does not require any special tools beyond what is used for normal strap installation.

How does this bracelet compare in weight to a steel bracelet?

At 3.2 oz in its longest configuration, the Grade 2 titanium bracelet weighs approximately half what a comparable steel bracelet for a 50mm watch would. On a large-case dive watch worn all day, that difference is noticeable. Reviewers specifically cite the low mass as a positive factor for all-day and diving use.

The Bulletproof Zone Promise

When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.

1. Authorized dealer of every brand we carry

Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.

We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.

2. Best price, guaranteed

If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.

Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.

3. Free fitment consultation

Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.

4. Trusted by thousands of customers

Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.

Price Match Guarantee — Terms

  • You must have purchased the item from our website before requesting the price match.
  • Discounted items and "free with purchase" items are not eligible.
  • The item must be in stock on the competitor's website at the time of your request.
  • The price match is valid for six months from the date of your purchase.
  • The competitor must be an authorized dealer of the product. Auction sites (eBay, Overstock), discounters, and gray-market resellers do not qualify.
  • The competitor must operate an online store. Brick-and-mortar-only retailers do not qualify.
  • Price match applies to the item price plus shipping. Sales tax is excluded.

To request a price match, email us a link to the product on our site and the same product on the competitor's site within six months of purchase. We'll process the refund.
