Care Tips

Keep leather straps dry and conditioned using high-quality leather conditioners. Avoid prolonged exposure to water, sweat, direct sunlight, and extreme heat. Rinse rubber straps with fresh water after contact with saltwater or sweat, then dry gently. Air-dry nylon straps away from direct sunlight to maintain their durability.

Measure Lug Width

Use a caliper or ruler to measure the inner distance between your watch’s lugs in millimeters for an exact fit. Accurate measurement helps avoid ordering the wrong size.

Attach & Remove

Gently compress the spring bar with a proper tool to install or remove the strap without scratching your watch. For easiest installation, we recommend using our precision spring-bar tool (available separately).

Water & Sweat Exposure

Rubber and nylon straps are water-friendly—rinse and pat dry after exposure to moisture. Leather straps should avoid prolonged contact with water to prevent damage.

Tool Recommendations

For the easiest installation and removal, we recommend our precision spring-bar tool, sold separately — see Tools collection.

Warranty & Service

All straps come with a Lifetime Warranty against manufacturing defects.
This warranty does not cover damage caused by improper use, accidents, or normal wear and tear.
