Setup and Installation

Follow these steps to correctly attach the steel bracelet to your watch case. It is recommended to use appropriate watchmaking tools to avoid scratching the bracelet or watch.

1. Prepare Your Workspace: Ensure you have a clean, well-lit area. Place a soft cloth or mat on your work surface to protect the watch and bracelet from scratches.
2. Identify Spring Bars: Locate the spring bars on your watch case lugs and on the bracelet end links. These are small, spring-loaded pins that secure the bracelet.
3. Attach First End Link: Insert one end of a spring bar into the lug hole on one side of the watch case. Using a spring bar tool, compress the other end of the spring bar and guide it into the corresponding lug hole on the opposite side. Ensure it clicks securely into place.
4. Verify Secure Attachment: Gently pull on the bracelet to confirm it is firmly attached to the watch case and does not wobble.
5. Repeat for Second End Link: Attach the second end of the bracelet to the other set of watch lugs following the same procedure.
6. Adjust Length (if necessary): If the bracelet is too long, links can be removed. This process typically requires specialized tools and is best performed by a qualified watchmaker to prevent damage.

Operating the Clasp

The bracelet features a butterfly deployment clasp for secure and comfortable wear.

1. To Open: Locate the two small push-buttons on the sides of the clasp. Press both buttons simultaneously to release the clasp and open the bracelet.
2. To Close: Bring the two ends of the bracelet together. Align the clasp components and press them firmly until you hear a distinct click, indicating that both sides of the clasp are securely engaged.

Maintenance and Care

Proper care will help maintain the appearance and functionality of your steel bracelet.

• Regular Cleaning: Wipe the bracelet regularly with a soft, lint-free cloth to remove dirt, oils, and perspiration.
• Deep Cleaning: For a more thorough clean, use a mild soap solution and a soft brush (like a toothbrush) to gently scrub the links and clasp. Rinse thoroughly with clean water and dry immediately with a soft cloth. Ensure no moisture remains in the crevices.
• Avoid Harsh Chemicals: Do not expose the bracelet to harsh chemicals, solvents, or abrasive cleaners, as these can damage the steel finish.
• Storage: When not in use, store the bracelet in a clean, dry place, preferably in a soft pouch or watch box to prevent scratches.

Troubleshooting

If you encounter any issues with your bracelet, consider the following common solutions:

• Bracelet Feels Loose After Installation:

  Solution: Ensure the spring bars are fully seated in the lug holes. Gently pull on the bracelet to confirm it is secure. If it remains loose, the spring bar may be bent or damaged and require replacement.

• Clasp Not Closing Securely:

  Solution: Check for any debris or foreign objects lodged within the clasp mechanism. Clean the clasp thoroughly. If the issue persists, the clasp mechanism may be bent or worn and might require professional adjustment or replacement.
• Bracelet Links Are Stiff:

  Solution: Dirt and grime can accumulate between links, causing stiffness. Perform a deep clean as described in the Maintenance section. If stiffness persists, lubrication with a tiny amount of watch oil (applied by a professional) might be necessary.
