When somebody walks into our office at Canary Wharf to sell a Rolex, the conversation goes much better in both directions if they’ve come prepared. Not in some elaborate, lawyered-up sense — just in the basic, practical way that means we’re talking about the watch on the table and not guessing.

We’ve watched both ends of this for years. The sellers who come in informed leave with a fair price and a quick payment. The ones who don’t sometimes leave with the same, but they also leave wondering whether they could have done better somewhere else.

If you want to sell your Rolex in London, here are three things worth doing before you walk into any dealer.

1. Find your paperwork — even the bits you don’t think matter

The single biggest variable in what a Rolex is worth on the day is whether it has its original box and papers. A Submariner with the full set will typically sell for 15 to 20 per cent more than the same watch on its own. That’s not dealer markup; it’s the market. Buyers pay more for completeness because it tells them the watch’s story.

So before you go anywhere, dig out the box. Find the warranty card. Look for the original receipt, the booklets, the swing tags, even the little wallet they came in. If you’ve had the watch serviced through a Rolex service centre or a respected independent, find those receipts too — service history matters more than people think, and a recent service receipt can be worth a few hundred pounds at the point of sale.

If you can’t find the paperwork, the watch is still saleable. It just sells for less. Don’t panic; just make sure you’ve genuinely looked.

2. Get a market value from more than one source

A common mistake is checking one dealer’s website, seeing a price next to a similar reference, and assuming that’s the value. Retail asking prices on dealer sites are not the same as the cash offers a dealer will make to a private seller — there’s a margin in there that pays for warranty, polishing, photography, marketing, and sitting on the watch until it sells.

A more honest baseline is to look at a few sources together. Chrono24 for the global asking price range. WatchCharts for tracked transaction data. eBay’s sold listings (the filter for completed sales, not the asking-price ones). Triangulating those gives you a defensible idea of what the watch is genuinely worth in 2026.

When you do that, you walk into the dealer with a number in your head – not a wishful one, a real one. The conversation gets simpler from there.

3. Decide your minimum before the offer is on the table

The most expensive moment in any watch sale is the thirty seconds after the dealer says a number. If you haven’t decided in advance what you’d say no to, you’ll often say yes to whatever lands close to your hopeful figure.

Work it out at home, calmly. What’s the lowest figure you’d accept and still feel fairly treated? Write it down. Ideally, talk it through with whoever you bought the watch with originally, or with a partner who’ll keep you honest.

When you walk in with that number, two things happen. You don’t get pushed below it. And — this matters more — you stop being suspicious of perfectly fair offers that happen to land above it.

A last thought

If anything in the conversation feels off — the dealer doesn’t want to look at the paperwork, the offer is well below your researched range, or you’re being rushed — walk out. A good buyer will respect a seller who knows what they have. We try to be that buyer. So do most of the people we compete with in London.

If you’d like an appraisal from us, visit us, call us or use the contact form. We’ll give you a straight answer either way.

Frequently Asked Questions 

How quickly can I be paid if I sell my Rolex to you?

Most sales are paid the same day, usually by bank transfer at the time of the appraisal once we’ve agreed on the price. For higher-value pieces or unusual references that need a bit more research, it can occasionally run into the next working day. Either way, you won’t leave the office having signed anything you haven’t been paid for.

Will you still buy my Rolex if it’s not working properly?

Often, yes. A non-running movement, a broken bracelet, a damaged dial — all serviceable issues, and we factor the repair cost into the offer rather than turning the watch away. Watches with replaced or non-original parts are more case-by-case and need to be looked at properly.

Do I have to come into the Canary Wharf office, or can I sell remotely?

Either works. If you’re nearby in London, Essex, Hertfordshire or Kent, an in-person visit is usually quickest. For sellers further out, we can arrange a fully insured collection through ZNG, complete the appraisal here, and pay you electronically once we agree on a figure.

Will I be expected to pay tax on the sale?

For most private sellers, a single watch sale falls under HMRC’s chattel rules and Capital Gains Tax doesn’t usually apply. If the watch has appreciated significantly, or you sell several pieces regularly, it’s worth a quick word with an accountant. We can’t give tax advice, but we’ll flag anything obvious we’ve seen come up.

Should I get my Rolex serviced before selling it?

Generally, no — at least not specifically for a sale. Dealers factor servicing into their offer either way, and a fresh service receipt from this year is worth more than one we’d commission ourselves later. If the watch hasn’t been serviced in seven or eight years and it’s running noticeably poorly, that’s a different conversation.
