An object in a dream often represents the characteristics you attribute to that object—what that objects usually brings to mind when you think of it. Meaning, if you dream about your watch that has been stopping a lot lately, your watch may represent your feeling that you're life has felt "stopped" or held-up or interrupted lately.
Also, the significance of an object in a dream may not be what it is, but it's context—how it is placed or being used, where it appears. For instance, an object that's out of place or in an unusual place can mean that whatever that object represents in real life feels "out of place" or off right now. Pay attention to what stands out about the object, as well as what the object itself symbolizes to you.
