Sell Your Used Smartwatch — 0% Fees

A used smartwatch typically sells for £40 to £250, and on WishThrift it costs you nothing to list — no fee, no commission, so you keep the whole amount you agree. Smartwatches are bought on compatibility and battery life, so name the exact model, say which phones it works with, and give a tested figure for how long a charge lasts.

The short version

Cost to sell here: nothing, at any price

Before you photograph it

Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.

Find the exact model and case size in the watch settings, and note the band size and type.
Charge fully and time a realistic day of use, including any always-on display setting.
Unpair from your phone, factory reset, and remove it from any account or activation lock.

The photographs that sell a smartwatch

Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.

The watch face on, showing the display working
The back sensor array and case, showing scratches
The settings screen with the model and case size
The band, charger and anything else included

Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.

Writing the title and description

Brand, model and case size: “Garmin Forerunner 255, 46mm, Black”. Case size matters for fit and band compatibility. State which phones it pairs with — a watch that only works with one platform needs saying, and it saves you a dozen messages.

Then state these in the description, because a buyer who has to ask is a buyer who might not bother:

Exact model, case size and material
Phone compatibility, and whether it needs a specific app or platform
Tested battery life per charge
Whether the original charger and band are included, and the band size

What buyers will actually ask

You will receive the same three messages about a smartwatch. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.

“Does it work with my phone?”

State the platform requirement plainly. Some watches are locked to one ecosystem and buyers get caught out constantly.

“How long does the battery last?”

Give a tested figure with the display settings you used. Smartwatch battery claims and reality diverge sharply.

“Is the charger included?”

Confirm it. Smartwatch chargers are almost always proprietary and awkward to replace.

Pricing it so it actually sells

Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.

The smartwatch value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.

What you keep, compared

On a £145 sale — roughly the middle of the range for a smartwatch — here is what the commission-charging platforms would take, and what you would keep on each:

Where you sell it	Fee	You keep
WishThrift	£0	£145
Poshmark	−£29	£116
eBay	−£20	£125
Mercari	−£14	£131
Etsy	−£9	£136

Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.

Timing and getting it to the buyer

Steady with a strong Christmas lift and a January bump from fitness resolutions. Fitness-focused models sell fastest in the new year.

Small and easy to post. Confirm the watch is unpaired and reset before it goes, or the buyer cannot set it up.

WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions

What is a used smartwatch worth?

Typically £40 to £250 depending on brand, model and age. See the smartwatch value guide for the range by condition.

Do I need to unpair before selling?

Yes. Unpair from your phone and factory reset, and check whether your brand has an activation lock that must be cleared. A watch still tied to your account cannot be set up by the buyer.

Does a scratched screen affect the price?

Yes, noticeably, because the screen is the whole face of the product. Photograph it at an angle in strong light and price accordingly rather than hoping it does not show.
