Key Features

• Automatic and Hand-Winding Movement – Powered by Orient’s reliable in-house caliber, this watch winds automatically with the motion of your wrist but can also be manually wound for immediate power when needed, offering flexibility and consistent accuracy. This dual functionality ensures the watch remains operational even during periods of inactivity, making it ideal for those who rotate multiple timepieces or prefer the tactile experience of manual winding.
• 40mm Diver-Style Case – The case size strikes a balance between modern wearability and classic proportions, fitting comfortably on most wrist sizes while maintaining a confident presence. Its diver-inspired design includes a unidirectional rotating bezel for tracking elapsed time underwater. The bezel’s precise markings and tactile feedback enhance usability, supporting safe time monitoring during brief submersion or recreational water activities.
• Sapphire Crystal – The front crystal is made from scratch-resistant sapphire, offering superior clarity and long-term durability compared to standard mineral or acrylic glass. This ensures the dial remains legible and protected from daily wear and tear. Sapphire’s hardness makes it highly resistant to scratches from everyday contact with surfaces like desks, door frames, or keys, preserving the watch’s appearance over time.
• Unisex Design – Engineered to suit both men and women, the watch features a neutral aesthetic and proportional dimensions that appeal across genders, making it a versatile choice for shared collections or gift-giving. The clean dial layout, balanced lugs, and moderate case thickness contribute to its broad appeal, ensuring it complements a variety of personal styles and wrist sizes.
