THE DESIGN STORY: THE ORIENT TRITON DIVER
Engineered for rugged aquatic performance and everyday wearability, the Orient Triton RA-EL0001B (frequently designated as the Orient Neptune) is a JIS Class 1 Diver compliant 200-meter professional mechanical dive watch. Drawing inspiration from Orient\'s legendary 300m Pro Saturation Diver, the Triton packs high-tier specifications into a versatile 43.4mm stainless steel case featuring a signature offset 4 o\'clock screw-down crown for enhanced wrist mobility.
The high-contrast matte black dial features bold applied hour markers heavily filled with Orient\'s bright luminous material for optimal underwater legibility. Subtle silver accents along the hands, marker surrounds, or bezel rim add an elevated tool-watch finish. Positioned at 1 o\'clock is Orient\'s signature fan-shaped 40-hour power reserve indicator, balanced by a date calendar display at 4 o\'clock. Protecting the dial is a flat, scratch-resistant sapphire crystal with anti-reflective coating, surrounded by a crisp 120-click uni-directional rotating dive bezel.
