With BST coming to an end this weekend I decided with some trepidation to risk it and remove the clock to turn back the hour.
Couldn't have been simpler,just pulled it out,it is a moderately tight fit,altered the time and pushed it back.
No loose pieces or anything else to impede progress.
I was quite surprised how cheap and flimsy the clock was,must have cost all of about £2.
Still it looks OK and does the job so no complaints.
