Octopus Kraken OCT-009 GMT Automatic Dive Watch — Hangzhou 6460, 39mm, Sapphire, 200m

The Octopus Kraken OCT-009 is a GMT automatic dive watch built around the Hangzhou 6460 GMT movement, in compact 39mm proportions. It pairs a 316L stainless steel case and rivet-style bracelet with a sapphire AR-coated crystal, a bi-colour luminous ceramic bezel, and a 24-hour GMT hand for tracking a second time zone. Rated to 200m with a screw-down crown and caseback, it is a versatile travel and dive watch that reads as comfortable in both casual and formal settings.

Key Specifications

Compact Proportions, GMT Function

At 39mm in diameter with a 47mm lug-to-lug measurement and an 11mm case profile, the OCT-009 sits in versatile, easy-wearing proportions that suit average wrists well and move comfortably between casual and formal wear. The GMT layout adds a 24-hour hand and a matching 24-hour bezel scale, so a second time zone can be read at a glance — a practical feature for travel or for anyone keeping track of more than one zone.

Hangzhou 6460 GMT Automatic Movement

The OCT-009 runs on the Hangzhou 6460 GMT automatic mechanical movement, self-winding through the natural motion of the wrist. Its dedicated 24-hour GMT hand allows a second time zone to be tracked alongside local time, making it the functional core of the watch’s travel-focused design.

Sapphire Crystal with AR Coating

The front crystal is genuine sapphire — highly scratch-resistant — with a blue anti-reflective coating that improves dial visibility and cuts glare under direct light.

Bi-Colour Ceramic GMT Bezel

The bezel uses a bi-colour blue and red ceramic insert, fully filled with luminous material across the 24-hour scale. Ceramic resists scratching and fading better than aluminium over long-term wear, and the luminous numerals keep the GMT scale readable in low light.

Dial, Hands, and Lume

The black dial uses bar and circle markers for a clean, high-contrast layout, paired with silver GS-style hands. Both markers and hands carry BGW9 luminous coating, delivering a strong, long-lasting glow in dark conditions for clear reading at night and underwater.

Rivet Stainless Steel Bracelet

The bracelet is a 316L stainless steel rivet-style design with a solid band and a push-button folding clasp, finishing the watch with a retro-leaning, substantial feel that complements the case.

200m Water Resistance

Rated 200m (20ATM) via a screw-down crown and caseback — suitable for swimming, snorkelling, and recreational diving. Always ensure the crown is fully screwed down before water exposure, and avoid operating the crown underwater.

Weight and Wear

At approximately 150g, the OCT-009 has a solid, substantial presence on the wrist without becoming heavy or cumbersome — a balance that suits both daily wear and more active use.

Warranty

Every OCT-009 is backed by a 2-year warranty.
