Checking And Adjusting The Rollover Number Setting - Citizen Eco-Drive F150 Instruction Manual

Checking and adjusting the rollover number setting

In order for this watch to correctly process the week information* received from
the satellite, a rollover number for each time period is set. The rollover numbers are
normally updated automatically.
If the rollover number setting is incorrect, the time and date may not be indicated
accurately. Check the rollover number setting and adjust it if it is incorrect.
* Called "Week number". Weeks are represented with numbers from 0 to 1023 (approx. 20-
year cycle).
