Clocks, Watches/Seikoasha Regulator Clock

Question
I bought a Seikosha (sp) regulator wall clock at a thrift store.  After cleaning the movement in a soap and water bath (it felt like it had seen a fire) and oiling the movement with clock oil (obtained earlier for use on other clocks) the clock works run.  However, even with the pendulum adjustment as short as possible the clock loses about 2hr every 12 hrs.  Is there another adjustment that I can make or should I look into another deeper cleaning of the works?

Answer
Mike, 10 minutes per hour is a major regulation problem.  A normal pendulum adjustment would not be able to correct this.  My first question is it the original pendulum to the clock?  Does the pendulum bob center in the front window?  If you could send me a photo of the clock showing the pendulum hanging I migh be able to help you further.  My clock shop email address is below.  I have a couple of clocks which I think might be similar to yours, one being a Seiko and I am not sure of the other right now.

As far as cleaning, a clock should be cleaned throughly and we recommend proper cleaning solutions, not soap and water.  Some soaps will leave residue, but if yours was cleaned throughly it might be okay.  When we clean a clock we dismantle it to insure all areas are covered, such as mainsprings, centershaft and hour tube, bushings and levers.

If it is running, the cleaning and oiling would have nothing to do with the problem of running slow.  If a suspension spring is too thin, the pendulum will swing further, slowing down the clock.  But not the rate you mention.   Right now I just don't know.  If it is running too fast, there are more common causes for that.

Send me a photo.

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.
