Key Features
- Seagull ST2557 Automatic Movement – A self-winding mechanical movement that harnesses the motion of your wrist to keep time. This eliminates the need for battery replacements and ensures consistent performance over time. The movement is entirely mechanical, requiring no external power source, and is designed for long-term reliability with proper care.
- 45mm Stainless Steel Case – A bold, masculine size crafted from durable stainless steel, providing strength and resistance to corrosion. The 45mm diameter makes a strong visual statement on the wrist, suitable for medium to large wrists, while the 15mm thickness adds a solid, substantial feel without being overly bulky.
- Sapphire Crystal Glass – Highly scratch-resistant and optically clear, this premium material protects the dial from daily wear, including exposure to keys, screens, and other common surfaces. Sapphire is one of the hardest transparent materials used in watchmaking, ensuring long-term clarity and durability.
- 10ATM Water Resistance (100M) – Rated for depths up to 100 meters, this watch is suitable for swimming, snorkeling, and other surface water sports. It can withstand accidental splashes, rain, and brief submersion. However, it is not intended for high-impact water activities like scuba diving or deep-sea diving.
- GMT Functionality – Track a second time zone using the dedicated GMT hand, which completes one full rotation every 24 hours. This feature is especially useful for frequent travelers, remote workers, or anyone coordinating across multiple time zones. The ability to monitor home and destination times simultaneously enhances practicality in a globalized world.
- Super Luminous Dial – The hour markers and hands are coated with luminous material that absorbs light and glows in low-light or dark conditions. This ensures readability during nighttime, early mornings, or in dimly lit environments such as airplanes, offices after dark, or outdoor adventures.
- Date Display – A practical calendar function positioned at the 3 o’clock position, providing quick and easy access to the current date. The date window is clearly legible and complements the overall dial layout without disrupting the watch’s symmetry.
- Pin Buckle Closure – A secure and adjustable stainless steel pin buckle ensures a comfortable and reliable fit on the wrist. The buckle is easy to fasten and designed to stay in place during active use, offering both safety and convenience.
- Multiple Color Variants – The S8441 is available in five distinct dial and bezel combinations: Black-Black-Blue, Silver-White-White, Silver-Blue-Green, Black-Black-Khaki, and Silver-Black-Blue. These options allow for personal expression, whether you prefer a classic monochrome look or a more dynamic, multi-tone design.
