CODE41 has detailed the technical specifications of the movement powering their Open Heart project. The watch features the Sellita SW200-2 AJ Power+, a Swiss mechanical movement known for its reliability and robustness. This specific version has been enhanced to provide a 65-hour power reserve, allowing the watch to continue running for several days without being worn. The brand selected an Elaboré version of the movement, which offers a regulated accuracy of +/- 7 seconds per day. According to CODE41, this movement was chosen to strike a balance between high performance and value, ensuring improved technical specs without unnecessarily increasing the price point. The open-heart design is intended to showcase this mechanism while maintaining long-term endurance.
