Key Features
- Automatic Self-Winding Movement: Driven by the Seagull ST1901 caliber, this movement delivers consistent accuracy and requires no battery. It stores energy through daily wear and offers a 40-hour power reserve when fully wound, ensuring reliable timekeeping even during periods of inactivity. The mechanism charges naturally as you move, making it an ideal choice for regular wear.
- Chronograph Functionality: Equipped with a functional stopwatch feature, the chronograph allows precise measurement of elapsed time using subdials on the dial. To reset the chronograph hands safely, always stop the timer first—this prevents unnecessary stress on the internal components and helps maintain long-term accuracy.
- Sapphire Crystal Glass: The watch face is protected by scratch-resistant sapphire crystal, offering exceptional clarity and durability against daily wear. This high-grade material resists scuffs and maintains its polished appearance, ensuring the dial remains pristine over years of use.
- Genuine Leather Strap: Features a high-quality leather strap with a folding clasp and double safety push-buttons, providing secure closure and a comfortable, breathable fit. The design balances refinement and practicality, making it suitable for all-day wear in both casual and business environments.
- Luminous Display: The watch hands and hour markers are treated with luminous material, enabling clear visibility in low-light conditions such as dimly lit offices, evening commutes, or nighttime activities—without sacrificing the watch’s classic appearance.
- Unique Identification Code: Each watch case is engraved with a unique code that corresponds to the included after-sales card. This feature ensures authenticity and simplifies future warranty claims or service requests, giving you peace of mind with your purchase.

Important Notes
To begin using the watch, gently rotate the crown clockwise until you feel slight resistance—this indicates the movement is fully wound. Do not continue turning beyond this point, as overwinding may damage the mechanism. Always stop the chronograph before resetting to protect the internal components and ensure smooth operation. The watch comes with a unique engraved code on the caseback that matches the after-sales card; retain this card for warranty purposes. For detailed warranty information, refer to the manufacturer’s official policy. The package includes the watch, leather strap, and documentation. To maintain optimal performance, avoid exposing the watch to extreme temperatures, moisture, and impacts. Regular care and proper handling will help preserve its appearance and functionality for years to come.
