We use the same grading system of watch condition as the Timezone Sales Forum.
LNIB
A pre-owned watch that has been worn, yet is in pristine condition. Accompanied by the factory box(es), tags and documentation. No alterations from factory-delivered condition. The warranty papers must be stamped to establish the authenticity and validity of the watch; TimeZone does not allow sales of watches with “open papers.” No bracelet resizing or marks of any kind. 100%
Mint
A pre-owned watch that is in very nearly perfect condition. Signs of wear are visible with a low powered loupe. May be a watch that is in LNIB condition but not accompanied by the factory box(es) or documentation. May refer to an older watch that has been restored, so long as the restoration returned the watch to very nearly pristine factory original condition. Working perfectly, keeping excellent time, needs nothing. 97-99%
Near Mint
Showing very light signs of wear. Faint scratches on the case, bezel, bracelet or buckle are visible to the naked eye. Completely original in every way. Strap shows light use – may be bent or lightly creased, but not stained. Bracelet may be resized. The watch is working perfectly, keeping very good time and needs nothing. 93-96%
Excellent
Evidence of use is visible to the unaided eye. Scratches are light, but more numerous than “near mint”. If the watch has been restored, all original replacement parts have been used. Strap clearly used but no stains. No dents or dings are detectable, and the bracelet has little wear. Working perfectly, needs no repair or service. 88-92%
Very good
The watch shows what might be considered normal wear by a careful owner who wore the watch regularly. Scratches are evident, but no nicks or dings. May have replacement parts and/or a high quality redial. Running and keeping good time, though may need minor regulation. A sound, attractive presentation overall. 83-87%
Good
Nothing fundamentally wrong with the watch, though it has quite obviously been used. Running and wearable, but may gain or lose a few minutes over 24 hours. Case may show a few dings, nicks, or deep scratches. May have a redial that is not up to high standards. May not have all original parts. 77-82%
