Product Overview
The RATIO Pilot Skysurfer Series Watch brings a fresh take on classic flight watch design with a compact, versatile build that works just as well in the office as it does on casual outings. Hailing from Singapore, this analog timepiece stands out with its 38mm case—significantly smaller than traditional Type A pilot watches, which typically measure 48–50mm. This makes it an excellent choice for professionals seeking a refined, wearable accessory that doesn’t overwhelm the wrist. Powered by the reliable Japanese Caliber NH38 automatic movement, it delivers consistent performance without a date complication, ensuring clean functionality and smooth operation. Whether you’re dressing up for a formal occasion or keeping it casual, the Skysurfer blends heritage-inspired styling with modern practicality.









Key Features
- Compact 38mm Pilot Watch Design: Unlike bulkier aviation-style watches, the Skysurfer’s 38mm stainless steel case offers a balanced, wearable profile ideal for everyday use. Its smaller size makes it particularly suitable for individuals with slender wrists or those who prefer a more understated look without sacrificing style.
- Japanese Automatic Movement (Caliber NH38): Equipped with the dependable NH38 movement from Japan, this watch provides self-winding functionality with no date window—eliminating the common “ghost date” issue found in many budget automatics. It ensures accurate timekeeping and requires no battery, relying solely on motion to stay powered.
- Sapphire Crystal for Scratch Resistance: The dial is protected by genuine sapphire crystal, one of the hardest transparent materials available, offering exceptional resistance to scratches and maintaining clarity even with daily wear.
- Superior 200M Water Resistance: With a water resistance rating of 200 meters, this watch exceeds typical expectations for a pilot-style timepiece. It’s suitable for swimming, snorkeling, and other water-related activities, reflecting tight manufacturing tolerances and a well-sealed construction.
- High-Visibility Luminous Display: The entire dial and hands are coated with luminous material that charges quickly under light and glows brightly in dark conditions. This ensures excellent legibility at night or in low-light environments—critical for a functional pilot watch.
- Premium Leather Strap: Paired with a genuine leather strap, the watch delivers a classic, refined aesthetic that complements both casual and formal attire. The strap enhances comfort while maintaining durability over time.
- Screw-Down Signed Crown: The crown is screw-down type and features the brand’s signature, contributing to the watch’s water resistance and adding a touch of authenticity and precision to the overall design.

Benefits & Use Cases
The RATIO Skysurfer is designed for men who value both form and function in a single timepiece. Its 38mm case makes it ideal for office wear, business meetings, or dinner outings where a smaller, more refined watch is preferred. The absence of a date window gives the dial a clean, symmetrical appearance that appeals to minimalist tastes. Thanks to its 200M water resistance, it’s also a reliable companion for weekend adventures—whether you’re swimming, boating, or caught in the rain. The luminous dial ensures you can check the time in any lighting condition, making it practical for travelers, night workers, or outdoor enthusiasts. The leather strap adds a touch of sophistication, allowing seamless transition from day to evening wear.
