The Octopus Kraken OCT-0025 is a compact mechanical dive watch designed for enthusiasts who appreciate precision engineering and balanced proportions.

With a 37mm stainless steel case, the watch delivers the classic dive-watch presence while remaining comfortable on smaller wrists or for those who prefer vintage-inspired sizing.

Inside the watch beats either the PT5000 automatic movement or the Swiss SW200 automatic movement, both known for their reliability and smooth high-beat operation.

The watch features a 120-click unidirectional dive bezel, sapphire crystal with anti-reflective coating, and strong Swiss luminous material for excellent legibility in low-light conditions.

With 200 meters of water resistance, the OCT-0025 is built for everyday wear, swimming, and recreational diving.

Key Features

Precision Automatic Movements

The OCT-0025 is available with two proven mechanical movements:

• PT5000 Automatic Movement – a high-beat automatic movement operating at 28,800 vibrations per hour
• Swiss SW200 Automatic Movement – a Swiss-made movement widely used in premium microbrand watches

Both movements provide reliable timekeeping and smooth sweeping seconds.

Compact 37mm Dive Watch Case

The 37mm diameter case and 45.5mm lug-to-lug length create a balanced profile that fits a wide range of wrist sizes.

The slim 11.2mm thickness keeps the watch comfortable under sleeves while maintaining the durability expected from a dive watch.

Professional Dive Bezel

The watch features a 120-click unidirectional rotating aluminum bezel, allowing divers to track elapsed time safely during underwater activities.

The bezel provides precise tactile feedback and reliable alignment.

High-Visibility Swiss Luminous Material

The OCT-0025 uses Swiss luminous compound on the dial and hands.

Depending on the model, the watch features:

• BGW9 blue luminous
• Retro yellow luminous

This ensures excellent visibility in dark environments.

Sapphire Crystal With Anti-Reflective Coating

The watch uses a sapphire crystal with anti-reflective coating, improving scratch resistance and reducing glare.

Sapphire is significantly harder than mineral glass and is widely used in high-quality dive watches.

Solid Stainless Steel Bracelet

The watch is paired with a 316L stainless steel bracelet featuring:

• quick-release system
• solid construction
• secure folding clasp

This allows easy strap changes and reliable daily wear.
