Key Features
- Automatic Mechanical Movement with Manual Winding – Powered by a mechanical movement that winds itself through natural wrist motion, the watch maintains timekeeping accuracy with regular wear. For added convenience, it can also be manually wound by rotating the crown clockwise, allowing users to restart the watch easily after it has stopped.
- Self-Sustaining Operation – As long as the watch is worn regularly, the kinetic energy from arm movement keeps the mainspring wound, ensuring continuous operation without the need for battery changes. This makes it an eco-friendly and low-maintenance choice for daily use.
- Manual Winding via Crown – If the watch has stopped due to inactivity, simply turn the crown clockwise to wind it. The movement engages only in this direction—turning the crown counterclockwise will not wind the watch and should be avoided to prevent unnecessary strain. Once the seconds hand begins moving, the time and date can be set accurately.
- Over-Winding Protection – The internal mechanism is engineered to prevent damage from over-winding. Even if the crown is turned beyond full wind, the mainspring will not break, offering long-term durability and peace of mind for the wearer.
- Timeless Black Dial Design – The black dial provides excellent legibility and a sleek, versatile aesthetic that pairs well with a variety of outfits. Its minimalist layout ensures clarity while maintaining a classic watchmaking appeal suitable for both casual and semi-formal occasions.
- Robust Everyday Wearability – Built to withstand regular use, this watch is ideal for active lifestyles. Its automatic movement eliminates concerns about battery life, while the manual winding option ensures readiness even after periods of non-use.

Benefits & Use Cases
The SRPK99K1 excels as a daily-wear timepiece thanks to its automatic winding system, which keeps the watch running smoothly with regular use. It’s an excellent option for those who prefer mechanical movements over quartz, offering a tangible connection to traditional watchmaking. The inclusion of manual winding makes it practical for occasional wearers—simply wind the crown before setting the time to resume operation. Its lightweight construction and compact dimensions ensure comfort throughout the day, while the black dial provides a refined, adaptable look that complements both jeans and a button-down shirt or business-casual attire.

Important Notes
To restart the watch after it has stopped, wind the crown clockwise slowly until the seconds hand begins to move. Once the watch is running, set the correct time and date before wearing. Do not attempt to wind the crown counterclockwise, as this will not engage the winding mechanism and may cause resistance. The watch contains one internal product-specific battery (a mechanical component), which is not designed for user replacement. For warranty details, customers should refer to the provided link.
