A-5 UDT - Blue Sunray

Dive Into Distinction

The A-5 UDT Blue Sunray takes the proven operational design of the original USN BUSHIPS dive watch and adds a modern, vibrant twist. Its sunray blue dial catches light beautifully, paired with light blue luminous indexes that maintain clarity while offering a contemporary flair. Designed for reliability under pressure, the watch preserves the oversized crown and solid case features that ensured WWII Underwater Demolition Teams could safely rely on their timepieces during extended missions. Strap options include the Blue Tropic rubber or a solid stainless steel Beads-of-Rice bracelet, giving versatility without sacrificing field-ready performance.

Precision, Protection & Legibility

Encased in a 38mm sandblasted stainless steel case with 20 ATM water resistance, the Blue Sunray is engineered for serious submersion. A double-domed sapphire crystal with anti-reflection coating protects the dial while maintaining crisp legibility in harsh light. Deeply embossed indexes and raised minute tracks provide dimensional clarity, while the embossed brand and collection name remain subtly visible. Swiss Super-Luminova ensures low-light visibility both above and below the surface, keeping time accurate and readable under demanding conditions.
