Inside our factory




What we bring
Hardware, chipset and software under one roof
We cover the work between an idea and a watch on the shelf, so your team deals with one partner instead of several.
01
Hardware platforms
Industrial design, mechanical structure, antenna and RF, battery and sensor integration, with whole-device reliability testing in our own lab.
02
Chipset partners
We work with chipset partners to bring cellular, satellite and precise positioning into a watch-sized product.
03
Software platforms
Firmware, health and activity algorithms, and integration with distributed OS platforms and your own back-end systems.
Engineering
Four R&D centres in China
Our engineering teams are spread across four R&D centres.
