Eval for purchase question

[monastic]

How do most small watch sales/repair shops evaluate used quartz watches for purchase? Do they charge a test fee for time and resources to install a battery and test the watch, or is that considered a basic cost of operation?

Does anyone know where a precedent for this might be posted online? I did a search but could not find any shops that outline policies for this.

That is up to each shop, there is no set practice. As a buyer you should be able to evaluate by yourself for the few cases you buy in person. Most transactions are made online anyway.
