Clocks, Watches/Urgos moon dial gears


John, I read your response to an earlier question on Urgos UW03xxxx movements regarding the moon dial. My movement is UW03012 and the third gear for the moon dial (with the pin that moves the moon dial) has worn to the point it no longer consistently moves.  Is there a company that handles replacement gears for this moon dial?  This particular gear is plastic and about 1 1/2 inches in diameter.

Cal, I apologize for the delay in my answer.  I am using a temporary email program, and had briefly lost some of my pending emails.

It is very difficult to obtain parts for dials.  The suppliers just don't stock them.  Clock companies that build clocks and put their names on them obtain the components from other companies and sometimes they will change the supplier, or the supplier will change the design.  The components can be different but they work the same and appear similar from the outside.  To resolve your problem, there are a couple of ways to do this.  First, I would need a clear closeup photo of the gear, the exact diameter, and the number of teeth on the gear.  It would help if you can give me the measurement from the center of the gear to the pin.  This is a rather precision setup and everything has to be exact for it to work.  The second option would be to send me the gear and I can look to see if I have on in my stock or send an inquiry to my Internet Clocksmiths Group.  

Reply to my shop email address below (with the photos if you can) and I will give you more details.

Note concerning questions not related to Allexperts:  Because of my commitment to answering Allexperts questions within a prescribed time limit and the large backlog of clock work at my shop, I regret that I cannot answer personal email questions on a timely basis, other than Allexperts follow up questions.  I will try to answer these emails as soon as I can. Thank you for your patience.

As I am not a certified appraiser I do not give values of clocks over the Internet. There is very little published information on what I consider to be the value of "modern production clocks". However, 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. As clock case model label numbers are difficult to relate to the movements, it is helpful if you can give me the information usually found on the movements themselves. Modern clock movements usually have the information on the back plate of the movement. I have been a clockmaker for about 40 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 in Prattville, Alabama.


One of my greatest accomplishments was traveling to China to assist a clock factory in building clocks to the standards which we required at Emperor. 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.
