SEIKO PREMIER KINETIC PERPETUAL 7D48 - DATE ISSUE

After a dropping, the date display malfunction

Another watch with date malfunction 

Dial removed, ready for repairing work

Repair done and cased up

Recently two customers brought in their Seiko Premier Kinetic with Perpetual Calendar function because the date did not work after the watches dropped on the floor. Both watches are using the same movement caliber 7D48. I heard that this date issue after a drop is quite common for this caliber.
