SPB381J1
Explore two time zones with confidence with the Seiko Prospex SPB381J1 Automatic GMT Diver's Watch.
This exceptional timepiece combines Seiko's legendary dive watch heritage with sophisticated GMT functionality and a striking green dial. Built for serious divers and global travelers, the SPB381J1 delivers professional-grade 200-meter water resistance, a premium ceramic bezel, and the robust 6R54 GMT movement, creating a watch that performs flawlessly whether you're exploring coral reefs or crossing time zones.
Key Features:
• Stunning green dial with date display at 3 o'clock
• Seiko 6R54 automatic GMT movement - 72 hours power reserve
• 42.6mm stainless steel case with superior build quality
• Ceramic unidirectional rotating bezel - scratch-resistant and durable
• GMT hand for tracking a second time zone simultaneously
• Lumibrite hands and markers for exceptional low-light visibility
• Sapphire crystal with anti-reflective coating

Why This Watch Stands Out:
Built on Seiko's storied Prospex dive watch legacy, the SPB381J1 elevates the platform with GMT functionality for travelers and professionals who need to track multiple time zones. The 6R54 calibre delivers an impressive 72-hour power reserve, while the ceramic bezel ensures lasting beauty and scratch resistance.
The vibrant green dial creates a distinctive aesthetic that stands out from traditional dive watches, while maintaining the professional-grade performance Seiko Prospex is known for worldwide.
Perfect for divers, frequent travelers, GMT watch enthusiasts, and anyone who values professional dive watch capability combined with dual time zone functionality.
