The Divecore FKM HP Professional Diving Watch Strap comes standard with OEM Quick-Release Fat Spring Bars that can easily be removed and replaced as needed. Designed for flexibility with a unique mono-accordion pattern that won’t get in the way of the keeper. It also features a flat pin buckle and flat adjustment holes along the strap for easy micro adjustments. The strap’s locking feature ensures it stays secure, even under dynamic pressure.

Spring Bars: ISO-rated Japanese 2.5mm quick-release fat spring bars come pre-installed with this strap, making it compatible with Swiss dive watches. The DiveCore HP spring bars have a 0.9mm tip, slightly thicker than the standard 0.7mm tip. If the strap isn’t compatible with your watch, you can easily swap the fat spring bars for standard ones or contact our team for a free return.

American FKM Rubber: This formula is known for its superior resistance to heat, chemicals, and weathering compared to other rubber materials. It's often used in applications that require durability, such as in the aerospace industry.

What sets American FKM rubber apart from other formulas, like standard FKM or silicone rubber, is its specific chemical makeup, which is formulated to perform better in extreme environments. American FKM tends to offer:

1. Higher Heat Resistance: Can withstand temperatures as high as 300°F (150°C), which is ideal for use in extreme conditions.
2. Chemical Resistance: Resists oils, fuels, solvents, and acids better than many other elastomers.
3. Durability: It tends to have a longer lifespan in harsh conditions, making it ideal for long-lasting products, like watch straps exposed to sweat and moisture.
4. Elasticity: Despite its strength, it maintains flexibility and a comfortable feel, which is great for wearable items.
