There will be 7 movements but only the central one will have a battery. The others will be set to times for prayers, which vary according to sunrise/sunset.More to the point - will you be using 1 or 7 clock movements? we need to see the back as well as the face.
It's for a mosque. There are 6 prayers whose time varies with the seasons so the outer faces show when those prayers happen. The middle one shows the time of day. It will go somewhere on the facing wall in the photo. It is replacing the aesthetically challenged clock you can see to the lef of the doors!Are you having 7 clocks set at different time zones ?
Ah ... That begins to make sense. On first noting the 7 movements I was minded of the 7 face clock of Giovanni de' Dondi which showed the positions of the known planets at the time (1340-50 ish)The others will be set to times for prayers, which vary according to sunrise/sunset.
