Engraving on case back

I've stumbled upon a few watches with engraved case-backs, nothing obviously noteworthy I think. I've wondered if engraved casebacks usually affect the general value of the time piece one way or another. Can the engraving be removed without much affect to value, or is removal of the engraving something to be avoided?

Thanks in advance for all views/insights.

99% of the time I won't buy a watch with an engraving. It would have to be a good deal and something I really wanted. It will affect the value, but how much depends on the rarity of the watch. At the extreme ends of the spectrum, a very rare specimen won't be terribly affected, but a garden variety example might lose a third of it's value.

You can have the engraving filled and then polished. A top notch goldsmith could match the gold alloy color, but it would never look the same as it was new after the work and polishing.

Thanks Denis!

Have a look throughout the attached thread but the specific link is to the treatment of an engraving on a clasp.
