Pocket Watch Marks

How is this pocket watch?

I fell on my pocket watch grandfathers of the date of 1907 given as graduation gift. My Device camera is broken and I have no pictures. It is a gold watch with hours and minutes on the face and a small print subface down with the second hand. it still winds and works, but time is not very accurate. it is in good condition and is very flowery. the rear seat opens revealing my name and grandfathers birthday. ACC is marked with a star and CO crescent between words and trade mark under it. It also has a number identification. I was wondering if you knew anything about this company or how it might be useful. Thank you for any help

I do not know what it's worth, but please do not sell it! You can keep as a family heirloom and pass it through the generations. This will be a worth far more than its monetary value.
