Key Features
- Automatic Self-Winding Movement: No battery required—this watch winds itself through the natural motion of your wrist. For initial use, manually turn the crown 15 full rotations to fully charge the mainspring. Once worn regularly for more than 10 hours a day, manual winding becomes unnecessary as daily activity keeps the mechanism powered. All functional sub-dials and hands operate correctly, ensuring accurate timekeeping and calendar functions.
- Skeleton Dial with Tourbillon Display: The transparent dial reveals the complex inner workings of the mechanical movement, including the rotating tourbillon, offering a mesmerizing view of the watch’s engineering. This open-heart design highlights the precision of Forsining’s Tiny Equipment Composing Technology, a proprietary innovation that ensures each component functions in harmony.
- Premium Stainless Steel Construction: Features a stainless steel case, crown, and caseback, providing durability and resistance to corrosion. The matching stainless steel band includes a secure clasp for a comfortable and reliable fit throughout the day, making it suitable for extended wear in both professional and casual environments.
- Water-Resistant Design: Engineered with a water-resistant structure to protect against splashes and brief exposure to moisture. However, it is not suitable for swimming, diving, or showering—avoid submersion to maintain long-term performance and protect the mechanical movement.
- Patented Mechanical Technology: Incorporates Forsining’s proprietary Tiny Equipment Composing Technology and patented mechanical innovations, ensuring precision and longevity in timekeeping performance. These advancements reflect over a decade of expertise from a company founded in 2006 and recognized as a global leader in automatic and mechanical watch manufacturing.
