(6) Very Good
Overall, the watch gives a sound, attractive presentation of what would be considered regular light worn watch from as former careful owner. Light scratches and hairlines are evident, but only a very few nicks or dings. If the watch has been restored, only original parts have been used. The dial can be in the range from near perfect condition to very fine and with even patina.

Though the watch has quite obviously been used, there is nothing fundamentally wrong with the watch. Case may show use and has dings, nicks, or surface scratches. May have a very fine to even or odd patina.
A wearable watch that runs smooth, but it may gain or lose a few seconds over 24 – 48 hours. 77-82%
Even an untrained eye could tell the watch is close to become worse for wear. A well-used watch that may look used, but it still is working well although its dial and case my look rough. May require restoration of dial as the patina has erased some original features from the dial original design. The watch has all is part intact but they may not be in super perfect condition. Some might call it a roughly used watch which has seen better days.
A watch that may be running erratically, but the mechanics and appearance could be in a far bette state. 66-76%
The watch shows abuse, requires service and/or restoration. May have major cosmetic flaws, missing parts, may not run at all. A speculative piece, but a ‘fix-up’ may be too generous to bear.
The watch is not junk, but it requires lots of work to be made wearable. It may not add up. 55-65%
(2) Scrap / Parts
This is more a collection of parts than what at one time may have been a functioning timekeeper. Missing parts, may have rust/ corrosion, only worth restoration if your grandfather had it in WWI.
The watch does not work, and most people would call it junk. Probably you should let it go 54%-
Your watch description must be explicitly stated in a full or intermediate grade as set out above.
If your watch does not fall precisely into one of the grade categories, you may use an intermediate indication such as “Good +” and provide a description of why an intermediate grade was used, for example
“Cosmetically rough, but just received a full mechanical overhaul (service, oiling & adjustment), a new strap, and the watch runs perfectly.”
