I have set the watch to London time and set the date month and year correctly. However the day sun dial does not record the correct day of the week. Hiw can I resolve this issue

You might have to adjust the hand zero position of your subdial. Press the a button for about 6 seconds (two beeps) and the screen should read "SUB". Adjust the position of the day hand using the B and D buttons and finish the process pressing the A btn.
