          BUILD GUIDE

          Compare the three build levels

          The main differences are power reserve and exterior finishing. Choose the level that matches your priority.

          Japanese movement

          Best value

          Reliable everyday performance with an approximate 24-36-hour power reserve.

          • Approx. 24-36-hour power reserve
          • Clean, practical finishing
          • Best for value-focused buyers
          Swiss movement

          More refined

          A higher-level option with an approximate 48-72-hour power reserve and improved exterior details.

          • Approx. 48-72-hour power reserve
          • Longer overall power reserve
          • More refined exterior finishing
          • Best balance of performance and detail
          Original appearance

          Top appearance

          The highest-level appearance version, made for customers who prioritize visual detail.

          • Top exterior version
          • Highest-level visual detailing
          • Best for appearance-first buyers

          Quick guide: Japanese movement is approximately 24-36 hours, while Swiss movement is approximately 48-72 hours, so Swiss delivers a longer power reserve across the range. Original appearance is the top version for exterior finish. Approximate figures may vary by model.
