Dr. Jabbour brings more than 30 years of experience collecting antiques and fine art to his interest in clock and watch appraisal. The precision and aesthetic eye of a retired Plastic Surgeon complements the precision and complexity of the finest clock and watch movements as well as the beautiful cases which house them.

Dr. Jabbour began his clock appraisal training through the National Watch and Clock Collectors Association followed by the Core Course in appraisal studies and the Uniform Standards of Professional Appraisal Practice through the International Society of Appraisers.  He completed the rigorous Watch Appraisal course, again through the National Association of Watch and Clock Collectors and the ISA.  He is an ongoing student in the Clock Repair Course sponsored by The Potomac Clock Guild.

Dr. Jabbour is the President of the Potomac Clock Guild and is also a member of The National Association of Watch and Clock Collectors, The Horological Association of Virginia and The American Watchmakers-Clockmakers Institute of which he is the new Chairman of the Ethics Committee.

Just as he specialized in his medical career, Dr. Jabbour specializes in clock and watch appraisals and not general personal property.  You can be assured that his total concentration is on your clock , watch or collection.  Attention to detail is assured.

Dr. Jabbour's appraisal reports are unbiased and confidential.  He does not purchase any items which he appraises, nor are fees based upon the value of your possessions.  They are based upon a straight hourly fee for evaluation, research and report preparation.

Dr. Jabbour is available for private consultation in your home or office and for preliminary evaluation via email photographs. 

Please contact Dr. Jabbour at email or 845-325-5071.
