The sale, and the column the house kept

Sotheby's Hong Kong's Important Watches sale — sale number HK1766 — ran in three sessions across Friday 18 and Saturday 19 September. Session 1 offered lots 2201 to 2323 from 11:00 HKT; Session 2 lots 2324 to 2457 from 15:00; Session 3 lots 2458 to 2612 from 11:00 on the Saturday. Those three ranges and three starting times are printed on the house's own sale page, which this desk read on 20 September. The same page offers one blue button: View 372 results.

Read further and the results stop. Every one of the 372 lots carries the same marker in the house's own lot data — ResultHidden — in the field where a sold price belongs. The house's own pages ship a single label for that state: "Log in to view results". The lot page for the Cartier Cheich, the object this sale was built around, gives the estimate in full (HK$8,000,000 to HK$40,000,000), the case number, the certificate and the 38 by 27 millimetre case, and no price at all. A day after the last hammer fell, the desk counted 372 lots and not one published result.

This is not a new wall. The desk's Chinese-language sister piece hit the same one in the jewellery department three days earlier, on Sotheby's High Jewelry sale of 17 September, and reached the same conclusion, which is that the estimate column is the half of the record a house cannot gate (蘇富比香港珠寶 185 件收槌).

The ladder, built lot by lot

The house publishes an estimate for every lot it offers. Estimates are not results: they are the house's own judgement, printed in advance, free to read, and checkable one lot at a time. This desk read them for all 372 lots and added them up itself. The sums below are the desk's, not the house's — the house publishes no total for this sale.

The 372 low estimates come to HK$242,615,000. The 372 high estimates come to HK$473,305,000. The median lot carries a low estimate of HK$160,000 and a high of HK$320,000 — exactly double, which turns out to be the house's habit rather than a coincidence: 133 of the 372 bands are set at precisely two times the low figure.

That is a broad catalogue with a thin top. Of the 372 lots, 243 — 65.3 per cent — carry a low estimate of HK$250,000 or less, and 319 — 85.8 per cent — sit under HK$1,000,000 at the low. Fifty-three lots start at HK$1,000,000 or more. Seven start at HK$5,000,000 or more. Twenty carry a high estimate of HK$5,000,000 or better. Rank the catalogue by high estimate and the top ten lots account for HK$191,500,000 of the HK$473,305,000 total: 40.5 per cent of the sale's ambition resting on ten objects.

The three sessions are not the same size. Session 1 lists 110 lots where its printed range of 2201 to 2323 holds 123 numbers; Session 2 lists 122 of 134; Session 3 lists 140 of 155. Forty lot numbers inside the printed range do not appear among the 372 lots the house lists.

Where the house put its uncertainty

Divide each lot's high estimate by its low and you get the width of the band the house drew around its own conviction. Across the sale the median band is 1.82 times wide. The narrowest is 1.25 times — lot 2479, a platinum Cartier Tank Normale retailed in London, banded HK$480,000 to HK$600,000. The widest is 5.00 times.

The 5.00 belongs to lot 2292, the Cartier Cheich, banded HK$8,000,000 to HK$40,000,000. It is the widest band in the sale, and it sits on the lot with the highest high estimate in the sale. Whatever else the catalogue says, the house's own numbers say it did not know what that watch would make — and it wrote that uncertainty into the estimate, at the very top of the ladder.

The desk found the opposite arrangement three days earlier in jewellery, where the widest bands went to the largest stones and the tightest to signed designs. Here the tight bands belong to the assured, catalogue-known objects and the single widest belongs to the one with no comparable.

The named lots

The Cartier Cheich is the object the sale was built around, and the house's own lot page answers it with a history rather than a superlative. Cartier sponsored the Paris-Dakar rally from 1983 and offered a wristwatch — not a cup — as the prize for winning consecutive editions. Gaston Rahier won in 1984 and 1985 and was the first and only recipient. Four Cheich watches were made in that period; in 2010 Cartier made a fifth, a unique white gold example marked "No. 1 of 1", for Giorgio Seragnoli, co-author of the Cartier Bianco book. Quartz and jewelled, 18k white gold, case number No. 1, 3316AF and 62020C, on a brown Cartier leather strap.

Two lots carry the sale's joint-highest low estimate, both F.P. Journe Tourbillon Souverain wristwatches at HK$15,000,000 to HK$30,000,000. Lot 2400 is the pink gold one, circa 2005, with a black mother-of-pearl dial and calibre 1403, which the house's own description says was "produced in a highly exclusive edition of just 5 pieces" to commemorate the 50th anniversary of Sincere Fine Watches, the Singapore retailer. Lot 2579 is its platinum counterpart, circa 2006, also made for Sincere.

The third lot named in advance was lot 2507, a Cartier Crash, reference 2774, in white gold and sapphire-set, circa 2010, which the house calls "possibly unique" and bands at HK$4,500,000 to HK$10,000,000. It heads a six-lot Crash ladder the house built deliberately: lots 2502 to 2506 run from HK$1,600,000 to HK$4,000,000 in overlapping bands, ending at the sapphire example. Cartier is the sale's organising principle — 77 lots carry the name, against 86 for Patek Philippe.

What got reported, and what it is worth

Two trade outlets reported prices from this sale, both on 18 September. Watch Collecting Lifestyle gave the Cheich as "HKD 26,500,000—approx. USD 3.4 million", without stating whether that figure carries the buyer's premium. Hodinkee, under Andy Hoffman's byline, gave HK$26,520,000 "including fees" and attributed the number to a Sotheby's statement. Both described it as a record for the most valuable Cartier wristwatch sold at auction.

The HK$20,000 between them is settled by the house's own premium schedule. Premium on a HK$21,000,000 hammer runs to HK$5,520,000 — 28 per cent on the first HK$15,000,000, 22 per cent on the next HK$6,000,000 — for an all-in HK$26,520,000 exactly. Hodinkee's figure is therefore the purchase price, and the hammer underneath it is a round HK$21,000,000: inside the house's own HK$8,000,000-to-HK$40,000,000 band, above the low. Set against the previous benchmark, the yellow gold Cartier London Crash the house sold in April and reported in its own post-sale release at HK$15,616,000, that is roughly 70 per cent more.

Hodinkee's second price fills in a gap in the house's own listing. It reported a Cartier London Midi Pebble, made in 1973 or 1974, at HK$3.8 million including fees, a record for a Pebble. The house's catalogue holds exactly one Midi Pebble — lot 2242, banded HK$950,000 to HK$1,500,000. The same article reported that lot 2241, a Cartier London Maxi Pebble, was withdrawn after it was found to share a case serial number with another example due at Monaco Legend Auctions in October. Lot 2241 is one of the forty numbers inside the printed 2201-to-2612 range that never appear among the house's 372.

Beyond those, nothing. Neither article gives a sale total, a sell-through rate or a lot count, and neither mentions that the house's own pages withhold every price. Other tallies are circulating, and none of them is the house's: HK$255,992,320 at a 56.1 per cent sell-through has been quoted, while the aggregator page this desk read on 20 September carries HK$423,220,400 at 90 per cent across 410 lots. The two do not agree with each other, neither agrees with the house's own 372, and the desk could verify neither against a primary source.

The three numbers a watch sale runs on

An estimate is the house's published range. The hammer price is the last figure the auctioneer accepts. The purchase price is the hammer plus the buyer's premium, which Sotheby's Hong Kong's own Conditions of Business for Buyers — the July 2026 update, published as a PDF on the house's site — sets at 28 per cent of the hammer up to and including HK$15,000,000, 22 per cent of the next slice up to HK$60,000,000, and 15 per cent of anything above that. The same document defines the reserve as "the confidential minimum Hammer Price at which an auction Lot can be sold". The sale page itself carries the matching caveat, that its results are "inclusive of any Sotheby's Premiums and exclusive of any applicable taxes and costs" — which is why a figure quoted off a sale page and a hammer price are never the same number. Where a lot carries a guarantee the arithmetic gains a second layer, which this desk set out on 17 September (The consignor's contract).

For the Hong Kong collector

If you are deciding whether to bid in November, the useful thing in a gated sale is not the total. It is the shape, and the shape is readable.

The ladder tells you where the house's own confidence thins, and in September it was thinnest at the very top. The single widest band in the sale, 5.00 times, sat on the single most singular object — the house declining to take a position on a watch it had no comparable for. A wide band is not generosity to a buyer. It is the house admitting it cannot price the thing, and the reserve, which the conditions call confidential, sits somewhere inside it.

The floor of this catalogue is unusually deep, and that is where the room is softest. Two-thirds of the lots were banded at a low estimate of HK$250,000 or less and 44 carried no reserve at all, which is where a collector bidding to a real ceiling can still be the last bidder standing. The middle is the harder ground. Between HK$1,000,000 and HK$5,000,000 at the low estimate sit 46 lots — and that is the band where a room that has just watched the top of the market get repriced will test its own nerve first.

The dates to watch

The November calendar is already published, on the houses' own pages, and one date this desk had pencilled is wrong.

Phillips' The Geneva Watch Auction: XXIV runs 7 and 8 November. Sotheby's holds its Geneva Important Watches sale on 8 November under sale number GE2604. Then the Hong Kong watch week arrives earlier than the desk's calendar carried: Phillips' The Hong Kong Watch Auction: XXIII runs 21 and 22 November, not the 23 to 26 the desk had written down. Those dates come from Phillips' own sale pages, read on 20 September, and they are the ones to diarise.

What to watch is not the totals. It is whether the houses publish results at all, since September's watch sale did not, and whether any house draws a band as wide as the Cheich's 5.00 times for an object with no comparable. If Geneva prints tight bands across the top of its catalogue, September's uncertainty was about one watch. If a 5.00 comes back, the uncertainty is about the market.
