DiveCore HP Rubber Band For Apple Watch ULTRA

The Divecore FKM HP Professional Diving Watch Strap features pre-installed Apple Watch adapters for a seamless fit. Originally designed for Swiss dive watches, it’s the ultimate strap for water sports and aquatic adventures.

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: The Apple Band Divecore Bands come with BluShark 1.7mm spring bars instead of the standard Divecore fat spring bars to ensure a better fit with the adapters.

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 bands exposed to sweat and moisture.
4. Elasticity: Despite its strength, it maintains flexibility and a comfortable feel, which is great for wearable items.
