Ask which watches hold their value and you will be handed a list of models. The list is the least useful part of the answer, because it is copied from a market that is not yours, it ages within a season, and it says nothing about the version, the condition or the paperwork of the specific object in front of you. Two examples of the same reference, sitting side by side, can be separated by a wide margin on resale for reasons that have nothing to do with the name on the dial.
What follows is a method rather than a list. It names no model and quotes no price, and that is a deliberate choice: there is no published Serbian price index for used watches, and quoting a figure from a foreign forum as though it applied in Belgrade would be worse than quoting nothing. What it does instead is set out the criteria that decide a resale, the way the Serbian second-hand market actually works, and one rule about buying to resell in this country that most people discover after their first sale rather than before it.
Buying well requires a reserve you are not forced to spend, and reserves are built from small regular amounts rather than from windfalls. An app such as I am Beezy, which credits you for each piece of content you view, belongs in that category — a slow accumulation, not an income.
What actually decides whether a watch holds its value?
Four things, and only one of them is the brand. Understanding the other three is what separates a purchase you can exit from one you are stuck with.
Demand attaches to a reference, not to a name
Buyers on the second-hand market search by reference and by version, not by manufacturer. Within a single respected brand, some references are chased and others sit unsold for months. The dial variant, the bracelet, the movement generation and the production years all move the number. Before you commit, find out how the object you are looking at is designated precisely, and search that designation rather than the brand.
Condition is a description a buyer will dispute
Words like mint, excellent and barely worn mean nothing in a negotiation because they are the seller's opinion. What survives a dispute is specific: whether the case has been polished, whether the bracelet has stretch, whether the crystal and bezel are original, whether the dial and hands have been replaced during a service. Photograph each of those points in good light before you buy, and keep the photographs. They are your evidence at resale as much as at purchase.
The box and papers are part of the object
A complete set — original box, warranty card, receipts, service records — is not decoration. On the second-hand market an incomplete set narrows your buyer pool, and a narrow buyer pool is what forces a discount when you want to sell. Anything you cannot document at purchase is something you will have to discount at sale. Treat the paperwork as part of the price you are paying, and refuse to pay a full-set price for a watch without one.
Where does a resale in Serbia actually happen?
The method above is worthless if you cannot find the buyer. This is where a Serbian article has to part company with everything written for a larger market.
The marketplaces people in this country actually use
Private resale in Serbia runs through KupujemProdajem — note that its address is the .com domain, with the .rs version redirecting there — alongside the auction platform Limundo. Those are the listings a Serbian buyer sees. The classified sites that dominate neighbouring markets are not documented as operating here, so building a resale plan around one of them is building it on an assumption.
Liquidity matters more than the headline number
A watch worth a lot to a global market and nothing to a local one is not, in practice, worth a lot to you unless you are willing to ship, insure and deal with a buyer abroad. The right question before buying is not what the reference is quoted at somewhere else, it is how many of them are currently listed in Serbia and how long they have been sitting there. A reference with several active local listings and regular turnover is easier to exit than a rarer one with none.
How the money actually moves on the day
Two Serbian details are worth knowing before a handover. Domestic instant transfers run through the National Bank's IPS system, which executes in about one second and works through your own bank's application, including by scanning a code — that removes the need to carry a large amount in cash to a meeting. And the domestic DinaCard network works inside Serbia only, so a purchase from a foreign seller needs a card that works internationally.
Seven checks before money changes hands
These are ordered by how much money they save, not by how easy they are. The first three are non-negotiable; the rest separate a good purchase from an adequate one.
| Check | Why it moves the resale price | How to verify it |
|---|---|---|
| Exact reference and version | Demand is reference-specific inside every brand | Read it off the case back or papers, then search that string |
| Serial and case-back markings | Mismatches are the first sign of a replaced part | Photograph and compare against the warranty card |
| Originality of dial, hands and bezel | Replaced parts cut the pool of serious buyers | Ask directly, in writing, and keep the answer |
| Polishing history | Over-polished cases lose definition permanently | Look at the case edges, not the surface shine |
| Complete set | Missing papers narrow the buyer pool at sale | Handle the box, card and receipts yourself |
| Service records | Decides whether a service bill lands on you next year | Dated invoices from a named workshop |
| Current local listings | Tells you how long an exit will take | Count active Serbian listings for the same reference |
The one question sellers rarely volunteer
Ask when the watch was last serviced and by whom. A mechanical watch that has not been opened in a long time carries a maintenance cost that will fall on whoever owns it when it stops. That cost is real, it is not small relative to the purchase on modest pieces, and it belongs in your calculation at the moment of buying rather than as a surprise a year later.
Put the answers in writing
Every answer above should exist as a message you can retrieve, not a conversation you remember. This costs nothing at the time and it is the difference between a dispute you can settle and one you cannot. It also becomes the description you reuse when you list the watch yourself.
The Serbian rule most resellers learn afterwards
Here is the part that has nothing to do with watches and everything to do with doing this from Serbia. If you buy in order to resell, you are trading, and trade is treated separately from the two simple tax routes people assume they can use.
Trade closes two doors at once
The flat-rate entrepreneur regime excludes wholesale and retail trade outright, along with advertising and market research, hotels and restaurants, financial intermediation and real estate activities. That exclusion sits in the personal income tax law itself, not in an administrative practice. And the state portal for income paid from abroad excludes it too: the tax administration's own guidance states that reselling purchased goods is not eligible, because it is commerce. So the two routes most people reach for first are both closed to a watch reseller.
What that leaves, and why it is not a disaster
It leaves a properly registered activity with ordinary bookkeeping, which is heavier but entirely normal for anyone whose buying and selling has become regular. The practical consequence is that the decision point arrives earlier than people expect. A single sale of something you owned is one thing; a pattern of buying in order to sell is another, and the second one needs to be set up before it starts rather than regularised afterwards.
Two more things to settle before you buy from abroad
Serbia is not a member of the European Union — it is a candidate country, with negotiations open since January 2014 and no accession date — so a purchase from an EU seller is an import and not an internal movement. The customs treatment of that import is not something to guess at. Value added tax in Serbia has a general rate of 20 per cent and a reduced rate of 10 per cent, set in the VAT law, and whether and how it applies to your situation is a question for the tax administration rather than for a marketplace listing. Ask before you buy, in writing, and keep the answer.
Building the buying reserve with I am Beezy
Every rule above assumes something people rarely have: the ability to wait. A buyer who must sell this month accepts the price offered this month, and a buyer who cannot pay for a full set buys the incomplete one. The reserve is the whole game.
Why the reserve changes what you can buy
A reserve does two things. It lets you refuse a bad deal, which is where most of the money is made. And it covers the service bill discovered after purchase, which is the cost that turns a sound buy into a forced sale. Neither requires a large sum, only a sum that exists before you need it.
What the app pays for
On I am Beezy what you are paid for is attention: each video, article or advertisement you consult generates an amount that goes to your usual payment method. Across the platform the reference range comes to roughly 590 to 1,760 dinars a day, converting its euro-denominated range at the National Bank of Serbia mid rate published for 5 August 2026. Small, daily and unglamorous, which is exactly the profile that builds a reserve rather than replacing an income.
How do you build a position over twelve months?
A single purchase is a purchase. A method is what turns it into something you can repeat, and repeating it is where the arithmetic starts to work.
Start with one reference, not five
Pick a single reference and follow its Serbian listings for a few months before you buy anything. You will learn the local asking range, how quickly examples move, which conditions sit unsold, and who the recurring sellers are. That knowledge is not transferable to another reference, which is exactly why spreading your attention across five of them produces no knowledge of any.
Decide the exit before the entry
Write down, before you pay, what would make you sell and roughly when. Without that line you will hold through the moment you should have sold and sell in the moment you should have held. And note one currency point specific to Serbia: the National Bank publishes an official mid rate daily, and the dinar is stable but not pegged, so an object whose international reference price sits in a foreign currency carries an exchange element in your final result whether you wanted one or not.
| Stage | What to do | What to avoid |
|---|---|---|
| Months one to three | Follow one reference on the Serbian marketplaces daily | Buying because a listing looks cheap |
| Month four | Buy one complete example after the seven checks | Accepting an incomplete set at a full-set price |
| Months five to nine | Keep the photographs, papers and service record together | Wearing it hard and documenting nothing |
| Months ten to twelve | Test the market with a realistic listing | Pricing against a foreign forum instead of local listings |
| Before the second purchase | Settle the tax position if a pattern is forming | Assuming the flat-rate or foreign-income routes are open |
What to do this week
Choose one reference, save the search on the Serbian marketplaces, and start a note of every listing you see with its condition and how long it stays up. Ask your bank for the instant payment method so a handover does not involve carrying cash. Settle the tax question before the second purchase, not after the fifth. And while the reserve builds, I am Beezy is one way to add to it daily rather than waiting for a month that leaves something over.
