Andy, as with most of succulents, once a day watering is too much. It can go for about a week or more for next watering, as long as you water thoroughly, till water drains out, and leave it alone to dry. Considering it is growing indoors, it will be taking a bit longer to dry at the root zone, compared to those we grow outdoors in part sun/part shade with all sorts of wind, and heat affecting it. It has very succulent leaves, that holds water very well.
Just give it some more interval in watering, so far it still looks okay to me, but be very careful in watering, they are not tropical plants that likes to be too moist.
