How to remove this battery clip

[P.C.]

I'm having trouble in knowing how to remove the battery clip from a small Casio Casiotron mens dress lcd watch. i cannot see any obvious slots or holes to insert a small pin etc . also not sure which is correct side to 'attack" Any suggestions please?

just kidding..take a sharp needle and pull the side metal piece (biggest hole...left on the picture) outward.

[P.C.]

Thanks Kasper , that worked! don't suppose you can name to module? I'm having trouble finding the correct method of setting the time, date etc.

Because I cannot tell exactly the number of the module from Your picture, You may try this (uncommon) setting instructions for an early Casiotron:
