Thanks for the response, yes a very ingenious mechanism indeed! Not wanting to be defeated by my clock; I completely disassembled again last night and cleaned everything again and added a little grease to the mechanical (plastic) components in an attempt to reduce the friction, all the fiddling has obviously done something as it hasn't lost a single minute this morning! I will see how I go.
