Tip & How-To about Watches

Changing Watch Batteries
Lots of posters ask "what is the battery in my (name of watch)" with a view to changing it yourself. This is a bad idea for many reasons. You don't have the tools or knowledge to remove a rotary screw on back, or the gasket sealant for a waterproof watch. Some fashion watches have 4 traditional screw and need professional grade jeweler screwdrivers. Also, there are about 20 batteries commonly used in watches, in various sizes and internal technology, Lithium Ion, Silver Oxide and Manganese Alkaline. If you buy them, you generally have to buy 10!

Don't sweat the details. Just take the watch to your local jeweler. They have all the batteries at hand and the tools to remove the back. It is done whilst you wait for $8 to $15!

either method will teach you but hands on under the watchful eye of a watchmaker would be better

ebay lists 7 search results between £30 - £190 I guess it depends on the exact age and model and providence of the particular watch. Only a valuation by someone who is familiar with this market would be able to tell you.

You may want to consider a complete over-haul of your Orient Ultramatic watch. I am Mike D of the RITE TIME BASICS, listed in the Repair Service Directory here at fixya.

As long as the watch is a quartz watch, the battery can still be changed by any store that changes watch batteries of that quality watch.  I would suggest either Tourneau or Precision Time.
