SunUs brand Established in 2000

Spirit of innovation and R&D like sun running keeps moving forwards day after day.

The company began with Tungli Gear Works. The company founder set up its own brand, SunUs, until 2000, and recalled that he went back and forth at home and abroad in his early days to expand the business. Different time zones let his watch read late at night while the scene outside of the plane was still daytime, which made him deeply impressed. To deliver brand orientation and spirit, SunUs brand logo was born. The design was inspired by the planets continuing running around stars from ancient times as the Sun is always shining on us — passing a mission of sustainable operation.
