Pre-Sale Viewing — The Days When the Lots Are on the Tables
Pre-Sale Viewing — The Days When the Lots Are on the Tables
The public exhibition before an auction, where serious bidders examine the catalogued lots in person
The pre-sale viewing is the public exhibition of catalogued lots held in the days immediately before an auction sale, during which prospective bidders may examine the gemstones, jewellery, watches, or other items in person, request condition reports, and consult specialists. For jewellery and watch sales at the major houses — Christie's, Sotheby's, Bonhams, Phillips, Dorotheum, MacDougall's, Heritage — the viewing is an essential part of the bidding process. Catalogue photographs and condition reports cannot fully convey clarity characteristics, colour nuances, fluorescence behaviour, setting condition, or the tactile and visual quality that determine whether a lot is worth its estimate or whether it carries a hidden problem that the catalogue description has glossed.
How viewings are organised
The standard viewing pattern for a major jewellery or watch sale runs three to five days in the city of the auction, typically opening on a weekend or early in the week before a Wednesday or Thursday sale. Lots are displayed in glass cases or, for higher-value pieces, brought out individually on request. Viewings at Sotheby's New York Magnificent Jewels and Christie's Magnificent Jewels run on dedicated multi-day schedules with appointment options for serious bidders, while smaller specialised sales (single-owner collections, watch-only sessions, regional sales) typically have shorter viewings of two to three days.
Major sales also tour key cities before returning to the saleroom for final viewing and the auction itself. A Christie's Geneva Magnificent Jewels sale typically tours New York, Hong Kong, and other major centres in the weeks before the Geneva viewing, allowing collectors in different markets to examine highlights without travelling to the sale city.
What to do at a viewing
Serious examination of a jewellery lot at viewing involves: handling the piece, ideally outside its display case under good lighting; examination under 10x loupe and bench microscope (the major houses provide both); checking measurements and weight against the catalogue description; confirming that any laboratory report referenced in the catalogue is the current one and that the report number matches the stone (girdle inscriptions on diamonds should be visible at 10x); inspecting setting integrity, prong wear, solder joints, and any past repair work; and examining the piece in different lighting conditions, including incandescent, fluorescent, and natural daylight where possible.
For watches, viewing extends to confirming reference and serial numbers against the catalogue description, examining the case for polishing or refinishing, opening the caseback (if the auction permits) to verify the movement and any service history, and operating the complications to confirm function. Auction houses' watch specialists are normally available during viewing to discuss specific lots and provide additional condition information.
Condition reports and specialist consultation
Beyond the catalogue description, the major houses provide formal condition reports on request, typically free of charge. The condition report is a more detailed written description than the catalogue entry, addressing wear, repair, restoration, and any concerns the cataloguing specialist has noted. For serious bidders the condition report is essential reading; the catalogue description is an introduction, and the condition report is the working document.
Specialist consultation during viewing is similarly important. The auction house's gem and jewellery specialists are available to discuss provenance, treatment status, comparable sales, and the cataloguer's reasoning for the estimate. These conversations are confidential and do not commit the bidder to any particular bidding strategy. Specialists also handle requests for additional laboratory reports, third-party appraisal, or extended viewing arrangements.
In the trade
Attending a pre-sale viewing in person is the standard practice for any bid above the casual range. Telephone and online bidders also benefit from arranging a representative to view the lot — many specialist dealers offer this service for clients in other cities. Bidders who buy without viewing or without commissioning a representative inspection are working from less information than the underbidder who attended in person, which is a significant disadvantage at the upper end of any bidding range.
The auction house's bidder registration process is normally completed during viewing days, simplifying the bidding mechanics on sale day. Major houses require credit references and identity verification for new bidders, particularly at the higher value tiers; arranging this in advance avoids last-minute complications.
