Antiquorum Grading System for Timepieces & Experts Overall Opinion

With a view to always provide a higher standard of service to its clientele, Antiquorum has introduced a watch appraisal grading system within its watch auction catalogues, providing immediate and detailed information on the condition of each lot offered for sale.

With the assistance of the Antiquorum Grading System, clients will have immediate answers to their questions regarding the condition of each lot, and will no longer need to request condition reports. In addition, with the Experts’ Overall Opinion, clients will benefit from the advice of Antiquorum’s experts, as each lot is given a grade based on its overall appreciation.

Although every effort has been made to remain objective, clients are nonetheless advised that any grading or condition report will, of necessity, be subjective. Clients are reminded that all statements made in the Antiquorum Grading System, in the Experts’ Overall Opinion or in any other condition report for any lot, are provided for information only and should not be considered a guarantee of any sort. Such information is given as an opinion for which Antiquorum cannot be held responsible. Furthermore, Antiquorum cannot be held responsible for any misrepresentations or incomplete information regarding the condition of any lot.


The lots described in this catalogue have been carefully examined and valued by Antiquorum’s experts and watchmakers, taking into consideration the esthetic, historical and technical interest, age and rarity, as well as the technology available at the time of production of each timepiece.

For such judgment to be as objective as possible, it must rest on a number of criteria, particularly with regards to the age of a lot. Indeed, a wristwatch of less than 50 years old cannot be judged with the same criteria as a Renaissance watch. This is the reason why some of the grades will only qualify for certain types of watches and will never be used for others.

For example, if, as a general rule, watches can be attributed grades from 1 to 4 for the case, the dial and the movement, watches less than 100 years old can be given grading 1 (as new), 3 (in very good condition), or 4 (in good condition). The latter, (grading 4), will be followed by one or more grading numbers to justify why the lot cannot be considered “in very good condition.” On the other hand, watches over 100 years old, of similar condition, would indeed be considered “very good” because of their age and would therefore qualify for grading 3. Needless to say, watches over 100 years old, even in the best state of conservation for their age, are unlikely to ever be considered “as new” and would therefore never be eligible for grading 1; for this reason, we have introduced grading 2 (in perfect condition).

At the end of each lot description, before the estimate, you will find a condition report box, with letters and numbers, divided into 3 sections: these are the grades given the lot with reference to the condition of its case, its dial and hands, and its movement.
