How to Value Your Watch Collection in 2026

Most collectors have a rough idea of what they paid. Far fewer know what their collection is actually worth today.

That gap matters more than it might seem. If you needed to insure your watches tomorrow, what figure would you put on the form? If a piece you bought five years ago has doubled in value, would you know? If you were approached with an offer on your Datejust, would you have any way of knowing whether it was fair?

Valuing a watch collection isn’t as complicated as it sounds, but it does require a method. This guide covers three approaches that work in practice, the factors that move the number up or down, and how to maintain an accurate record of value over time instead of doing a frantic estimate whenever you actually need the figure.

Why Valuing Your Collection Matters

There are three situations where accurate valuations become genuinely important.

Insurance. Standard home contents policies typically have per-item limits of £1,500–£2,000 for jewellery and valuables. A single mid-range Swiss watch will often exceed that. If you’re not carrying specialist watch insurance, or haven’t listed pieces individually on a scheduled items policy, you may be significantly underinsured without realising it. Insurers require a current market value to set premiums and pay out claims, and that figure needs to be yours, not something you’ve guessed at.

Selling or trading. The grey market for watches moves quickly. A reference that was trading at a discount to retail two years ago might be at a premium now, or vice versa. Knowing the current value of what you own lets you time decisions: when to sell, when to hold, whether an offer you’ve received is reasonable. Without that baseline, you’re negotiating blind.

Estate planning. For significant collections, watches are real assets with real value that needs to be properly documented. If you haven’t left a clear record, the people who come after you will struggle to establish what anything was worth, and may accept far less than the pieces deserve.

Method 1: Chrono24 Completed Sales

This is the most reliable method for most watches and the one professional appraisers use as a starting point.

Chrono24 is the world’s largest secondary market for watches, and it shows both active listings (asking prices) and completed sales. The distinction is important: asking prices reflect seller optimism. Completed sales reflect what buyers actually paid.

To use this method: go to Chrono24, search for your specific reference number (not just the brand and model, the actual reference number), and filter for sold listings. Look at the last three to six months. Discount outliers at both ends. What remains is a realistic range for your piece in current market conditions.

Be precise with your filters. A Rolex Submariner 126610LN is not the same as a 116610LN. The references are different, the values are different, and conflating them will give you meaningless numbers. Similarly, the same reference in steel and gold will have a different market, and the same reference with and without box and papers will sit at noticeably different price points.

If your watch has had modifications (refinished dial, replaced hands, aftermarket bracelet) then adjust down. Collector communities are serious about originality, and non-original parts reduce value by more than most sellers realise.

When Chrono24 data is thin

For less common references, rarer independent brands, or older pieces with limited recent sales, the Chrono24 data may be sparse. In these cases, use the available sales as a floor rather than a definitive number, and cross-reference with the other methods below.

Method 2: Dealer Quotes

A reputable watch dealer, one who actually buys and sells pre-owned watches rather than just retailing new, will typically give you a buying quote for nothing, or a market estimate for a small fee.

The key is understanding what a buying quote represents: it’s what the dealer will pay you, not what the watch is worth in the open market. Dealers need margin. A piece they’ll buy from you at £4,000 might be listed on their website at £5,200 a month later. The difference funds their business, not an error in your valuation.

For insurance purposes, you want replacement value: what it would cost you to replace the piece in the current market. That’s closer to the retail ask than the dealer’s buying price. When getting dealer quotes for valuation purposes, it’s worth asking specifically for an insurance replacement value rather than a buying price, and noting which you’ve received.

The advantage of dealer quotes over market data is that an experienced dealer can assess the specifics of your piece in person (condition, originality, dial quality, bracelet stretch) in a way that raw market data can’t. For pieces with significant variation in condition, this matters.

Method 3: Auction Results

For the top end of any collection (high-value independents, vintage pieces, limited references) auction results provide the most defensible valuations, particularly for insurance and estate purposes.

The major auction houses (Phillips, Christie’s, Sotheby’s) publish their results, and these are accepted by insurers and courts as authoritative evidence of market value. For a watch that trades in auction regularly, the last two or three hammer prices (plus buyer’s premium, which is typically 25–28%) give you a solid current range.

The limitation is coverage. Most everyday collector pieces don’t appear at auction. The data is most useful for watches valued above approximately £10,000–15,000, vintage references with an established auction track record, and pieces by smaller independent makers whose market exists primarily at auction.

For the bulk of most collections, Chrono24 completed sales plus a dealer quote will be more relevant and more current than auction data.

What Actually Affects the Value

Once you have a benchmark, several factors will move the real value of your specific piece above or below it.

Box and papers

This is the single biggest variable for most collectable references. A Rolex Submariner with original box and papers will sell for noticeably more than the same reference without them. The gap narrows over time as watches age, but for modern pieces (say, anything from 2010 onwards) it’s significant and worth quantifying.

Keep box and papers in a safe place. If you’ve lost them, it’s worth contacting the dealer or AD you bought from. Some can reissue documentation. It won’t be original, but any paperwork that evidences purchase provenance has some value.

Service history

A documented service history (records showing who serviced the watch, when, and what was done) adds real value, particularly for watches where mechanical condition is hard to verify externally. A buyer who knows a movement was serviced by a reputable watchmaker two years ago has more confidence in the piece than one buying blind.

For watches you’ve owned for some time, maintaining service records as you go is far easier than reconstructing history later.

Condition

Condition grades in watch sales tend to be: unworn/mint, excellent (minimal wear), very good (light wear), good (visible wear), and fair (significant wear). Each step down reduces value, and the reduction is non-linear. Moving from excellent to good is a bigger drop than moving from unworn to excellent.

Case condition matters most: heavy polishing that has rounded lugs, significant scratches or dents, and replaced or refinished dials all reduce value substantially. Bracelet condition matters, but is viewed more charitably since stretching and clasp wear are expected and a bracelet can often be replaced.

Market timing

Watch values move with broader market sentiment. The 2020 to 2022 period saw dramatic appreciation across the sports watch market; 2023 to 2025 saw correction. Individual references also have their own cycles. A model that appears in an influential film, gets worn by a prominent figure, or appears in a major auction can shift in weeks.

Valuations are a snapshot, not a permanent figure. For insurance purposes, updating annually is good practice. For active trading, you want to be checking current market data regularly.

Keeping Track Over Time

A one-off valuation is useful. A maintained record of valuations over time is much more useful.

For each piece, you want to know what you paid, what it was worth at various points, and what it’s worth now. That information tells you whether you’ve made a good investment decision, whether your insurance coverage is keeping pace with the market, and what your collection is worth as a portfolio rather than a list of individual items.

CurateMyWatches lets you record purchase price alongside a current estimated value for each watch in your collection. As you update valuations over time (which takes a few minutes per piece, a few times a year) the portfolio view shows you the delta: total cost versus total current value, broken down by piece. It’s not automated market pricing (no tool gives you a live secondary market feed), but it gives you an organised, maintained record that’s far more useful than trying to reconstruct everything when you actually need it.

For insurance purposes specifically, the ability to export a clean inventory list with descriptions, serial numbers, purchase details, and current valuations. It’s worth having this set up before you need it, not during a claim.

A Practical Starting Point

If you’ve never properly valued your collection, here’s a simple approach to get started without it becoming a project.

Work through each piece in an hour or two. For each watch: look up recent Chrono24 sold listings for the specific reference, note the range, and record your estimate in your collection tracker. Note whether your piece has box and papers, and whether condition is at, above, or below typical for the reference. That gives you a working valuation for each piece.

Then set a reminder to revisit this once a year, or any time there’s a significant market event (a model discontinuation, a new generation release, a prominent auction result) that could affect your specific references.

The goal isn’t a precise number down to the pound. It’s a documented, defensible estimate that you can show an insurer, use to make a selling decision, or hand to an executor. That document is worth considerably more than the few hours it takes to put together.

Frequently Asked Questions

How is watch value different from what I paid? What you paid is your cost basis. Current value is what the watch would sell for in today’s secondary market, which may be higher, lower, or roughly the same depending on the reference, market conditions, and the time elapsed since purchase.

How often should I update valuations? Annually for insurance purposes is the minimum. For references that trade actively or are known for price volatility, checking every six months is sensible.

Do modifications affect value? Usually negatively, and sometimes significantly. Non-original dials, replaced hands, aftermarket bracelets, and case polishing all reduce collector value. If your watch has modifications, factor in a discount versus pristine original examples.

Can I do this myself or do I need a professional appraisal? For most purposes (insurance scheduling, personal records, informal sale decisions) a self-conducted valuation using Chrono24 data and a dealer quote is sufficient. A formal written appraisal from a certified appraiser is worth getting for very high-value pieces, for estate purposes, or where an insurer specifically requires it.

What if my watch isn’t on Chrono24? Less mainstream references, independent brands, and vintage pieces may have limited Chrono24 data. In these cases, dealer quotes, specialist auction results, and community forums (TimeZone, WatchUSeek) for that specific brand will give you better data than a general marketplace.
