@@ -40,8 +40,7 @@ The main menu contains several settings covering Anton clock in general.
 * **Show Weekday** - Weekday is shown in the time presentation without seconds.
 Weekday name depends on the current locale.
 If seconds are shown, the weekday is never shown as there is not enough space on the watch face.
-* **Uppercase** - Weekday name and month name in the long format are converted to upper case letters.
-This can improve readability.
+**Show Weeknumber** - Weeknumber (ISO-8601) is shown.
 * **Vector font** - Use the built-in vector font for dates and weekday.
 This can improve readability.
 Otherwise, a scaled version of the built-in 6x8 pixels font is used.
