Question

I forgot to wear my watch (or ring), so I wasn't able to measure my skin temperature during sleep. Can my cycle not be predicted?

Answer

[Countries that only support Watch]

• Periods can be predicted based on cycle information entered by the user without measuring the skin temperature. By measuring the skin temperature, the difference in temperatures of the pre- and post-ovulation period can be detected and the ovulation date can be checked. A person's period can be more accurately predicted based on the date of ovulation.
• We recommend wearing the watch for at least 4 hours during sleep at night and at least 5 times a week if possible.
