Tips and Recommendations

• Try to clean the watch body as often as possible
• Use a soft-bristled toothbrush to clean those hard to reach places on the watch
• Please avoid using any direct chemicals (bleach, non-diluted cleaning agents, etc) to clean the watch
• Do not use any photo or light-emitting disinfectant/cleaning products as this may damage the watch screen or sensors
