Question
How do I remove the clock to change the battery in a concept clock, which is mounted in a crystal block like this one?:http://www.ebay.co.uk/itm/Concept-small-glass-chrystal-clock-TR-/201372912082?pt

Any help will be gratefully appreciated, thank you

Hazel, there were many types of these clocks made and the do have different mounting arrangements.  If there is no access from the back I would suggest that you try to pull it out by hand.  Some of these clocks have a small hole in the back that you put a in in to push the movement out, but I don't really remember the crystal clocks having this.  If that doesn't work, use a sharp tool like a knife and carefully slip it between the crystal and bezel of the movement, being careful not to mar the bezel.  The movements are usually held in with a rubber ring or spring clips on the movement.  I happen to have one in the shop right now, waiting for a new movement.  They are called fit-ups or inserts.  I will include a photo of it removed.  It uses the clips to hold it in.

Typo above.  I went back and added the part about the hole in the back.  I should have written that a PIN should be put in to push the insert out.  Again, I don't think the crystals had this.

Expertise

As much as I would like to offer values of clocks, I am not a certified appraiser and will not venture into giving an unresearched guess. There is very little published information on what I consider to be the value of "modern production clocks". Considerations are what the clock originally sold for, the condition of the case and movement, and particularly the area in which you live, the demand and the economy. ALSO, WATCHES ARE NOT MY FIELD. However, I can advise the clock owner on proper maintenance of a clock to keep it running, small corrections and adjustments and how to move a clock without damaging it. I can also advise on obtaining parts for clocks. It helps if you can send any information on the clock movement which is usually found on the back plate of the movement. I have been a clockmaker for about 35 years and was plant engineer in the mid 90's and later operations and engineering consultant at Emperor Clock Company in Fairhope, Alabama. I now have my own clock shop.

Experience

One of my greatest accomplishments was traveling to China to assist a clock factory in building clocks to the standards which we required. With the proper specifications and quality control, some beautiful clock cases were built. The factory people from the wood carvers to the plant manager were very congenial, friendly and I left a lot of wonderful friends when I returned from my trips.
