That Watch or Collectible Isn't as Liquid an Investment as It Looks

A Rolex tracker shows a price. An auction house gives a handbag an estimate. StockX shows a sneaker's last sale. All three look like a market price you could get today, the way a stock's quote is. None of them are. The gap between a collectible's quoted value and what it actually converts to in cash, fast, is the liquidity risk that gets skipped over in most "watches and collectibles as an investment" pitches.
A stock's quote is a live, executable price: place a market order and you get filled at something very close to that number, in seconds. A collectible's quoted "market value," whether from a price tracker, an auction estimate, or a marketplace's "last sale," is a record of a past transaction or an opinion, not a standing offer to buy from you right now.
To find out what you can actually get, you need a real buyer, and every real buyer takes a cut for taking the other side of an illiquid trade. That cut is the spread, and it is usually much wider than most collectors expect.
Luxury watches are one of the more liquid collectible categories, with active dealer networks and price trackers, so they make a useful floor for how wide the gap gets even in a "good" case.
According to LuxMetrix's 2026 guide to Rolex investment value, verified dealer bid-ask spreads on steel and gold models ranged from about 5.6% to 9.1% in early 2026, and after factoring in transaction costs, insurance and servicing, a Rolex typically needs to appreciate roughly 15% to 25% just for a buy-sell round trip to break even (LuxMetrix, retrieved 2026-08-09).
The wider watch market itself has been close to flat through mid-2026: the WatchCharts Overall Market Index posted a modest +0.2% in July, with Rolex up 0.2% and Patek Philippe up 1.5% that month, after a rougher stretch in May and June (WatchCharts' own July 2026 market update, retrieved 2026-08-09). Over a longer horizon, Knight Frank's 2026 Wealth Report put watches up 5.1% for the year among models with the strongest demand, and up 125.1% over the past decade, ahead of art, wine and coins (Knight Frank Luxury Investment Index, retrieved 2026-08-09). Both can be true at once: the index that measures what watches are notionally worth has done well, while the spread that measures what you would actually net on a fast sale has stayed wide. They are different numbers, and a collector who only checks the first one is missing the one that matters when cash is actually needed.
Auction houses look like the most transparent, price-discovering venue for a rare collectible: a hammer price, in public, in front of competing bidders. But the hammer price is neither what the buyer pays nor what the seller receives.
Sotheby's raised its buyer's premium to 28% on the lowest tier (lots hammering under roughly £1.5m) from 13 February 2026, with a 22% middle tier and 15% on the highest-value lots. Christie's runs a similar structure: 27% on its lowest tier, 22% in the middle, 15% at the top (Antiques Trade Gazette and The Value, both retrieved 2026-08-09). On the seller's side, consignors typically pay a commission of roughly 10% to 15%, sometimes negotiated lower for an especially desirable piece (MyArtBroker's guide to auction fees, retrieved 2026-08-09).
Stack both fees on a single hypothetical lot and the spread becomes obvious: a piece that hammers at $10,000 costs the buyer roughly $12,700 to $12,800 once the lowest-tier premium is added, while the seller nets only about $8,500 to $9,000 after commission. One "sale," one hammer price, and the buyer's and seller's real numbers sit 40% to 50% apart. That gap is the auction house's business model, and it is the reason a single quoted "value" for a collectible almost never matches what either side actually experiences.
Collectibles marketplaces built for faster turnover charge smaller fees, but the pattern is the same, and it applies well beyond watches. On StockX, sneaker sellers pay a tiered fee starting around 9% (down to 7% at the highest volume tier) plus roughly a 3% payment-processing charge, while buyers pay an additional buyer's premium of around 10% on top of the asking price. Between both sides, a typical round trip costs somewhere in the 12% to 13% range even before shipping (SendPayback's and Underpriced's 2026 StockX fee breakdowns, both retrieved 2026-08-09). Trading cards, wine and other collectible categories built around specialist marketplaces or consignment shops tend to sit in a similar range: fast, but never free, and never at the single number a price guide quotes.
For an Indonesian collector who needs cash quickly, the fastest option is often not selling the item at all, it is pawning it, and the numbers there make the same point even more directly.
Pegadaian's Gadai Luxury service accepts branded watches, bags and jewellery as collateral, but values a watch at only 60% to 80% of its secondhand market price, not its full quoted value, before it even calculates a loan against that reduced figure. The rental fee (a daily charge in place of interest) runs 0.09% per day, and the standard term is 30 days, with an administration fee of Rp2,000 to Rp125,000 depending on the loan size (Pegadaian's own product pages, retrieved 2026-08-09).
Worked through on a hypothetical, clearly labelled as such: a watch with a secondhand market value of Rp50,000,000 gets appraised at Rp30,000,000 to Rp40,000,000 (the 60-80% band), and a 30-day loan against that appraisal costs roughly Rp810,000 to Rp1,080,000 in rental fees alone (0.09% per day for 30 days on the loan amount), on top of the admin fee. That is fast cash, secured by an asset the borrower still owns and can redeem, but it is not the item's quoted value, and it is not free.
If you already track watches, art or other collectibles alongside your stocks and crypto, keep the number you use realistic rather than the optimistic tracker figure. NetWort's manual assets on your Holdings page let you record and update those values yourself, so your portfolio reflects what you could actually realise, not just what a price guide says. For the currency side of an international purchase or sale, you can also check the current USD/IDR rate and macro backdrop before you convert a quote into rupiah.
A related illustration of the same gap on a more liquid physical asset: physical gold carries its own round-trip spread, smaller than a rare collectible's, but real for the same underlying reason: someone on the other side of the trade is pricing in the cost and risk of holding an item that does not trade the way a stock does.
