How to repair CASIO MDV-106 or MDV-107. Replace Miyota 2115

In the video tutorial I show you how you can repair 90% of the faults that you may have with your CASIO MDV-107 or MDV-106 (Marlin hard), simply by changing its movement. It is a very simple repair and it only costs €5, so it is highly recommended to keep a Miyota 2115 movement in case one day our Casio MDV begins to fail.
