Checked August 18, 2026: Google Store is the best-confirmed route for trading in an old smartwatch toward a Pixel Watch 4, while Best Buy could be cheaper if its advertised sale price and trade-in quote are still available at checkout. For a valuable Apple Watch or Galaxy Watch, a private sale may produce more money—but with considerably more work and risk.
The key is to compare your effective cost, not an advertised “up to” figure:

| Best for | Route | Why it stands out |
|---|---|---|
| Official trade-in | Google Store | Direct smartwatch and fitness-tracker estimator integrated into the purchase flow |
| Potentially lowest retailer price | Best Buy | Advertised sale price plus a “Trade in and save” estimator, but the current promotion requires checkout verification |
| LTE buyers | Google Store Pixel Watch 4 LTE | Two years of Google Fi data advertised with qualifying LTE purchases |
| Highest potential proceeds | Private sale or resale marketplace | More pricing control and potentially higher proceeds for recent Apple Watch and Galaxy Watch models |
| Carrier deal | None confirmed | No current Pixel Watch 4 carrier trade-in offer was verified in the available first-party evidence |
There is no defensible universal winner for every watch owner. Google does not publish one fixed trade-in table for all eligible devices; the quote depends on the old watch’s model, manufacturer, configuration and condition.

Current Pixel Watch 4 prices
Google’s US configuration page lists the Pixel Watch 4 from $349.99. The displayed 45mm configuration is $399.99. Compare like for like: 41mm and 45mm watches are different purchases, and Wi-Fi/Bluetooth and LTE versions should not be mixed in a price comparison.
Before buying, select the exact combination of:
- 41mm or 45mm case;
- Wi-Fi/Bluetooth or LTE connectivity;
- color and band configuration; and
- your delivery ZIP code, where applicable.
See the Google Store configuration page for the current listed options. Financing shown on the product flow starts at $29.17 per month over 12 months, subject to eligibility and terms; monthly payments do not make the watch cheaper by themselves.
1. Google Store: the best confirmed trade-in route
Google Store is the clearest starting point because it explicitly accepts eligible smartwatches and fitness trackers and generates a device-specific estimate during checkout.

How to get your quote
- Add the Pixel Watch 4 to your cart.
- Choose the trade-in option.
- Identify the old watch or fitness tracker by manufacturer and model.
- Answer questions about size, connectivity and condition.
- Review the estimated credit before completing the purchase.
- After receiving the new watch, send the old device to Google’s trade-in partner.
The old watch must reach the trade-in partner within 30 days of receiving the new Pixel Watch 4, according to the product-page terms. The estimate is not guaranteed: the partner inspects the device and can reduce or reject the credit if the watch does not match the submitted description.
Google’s trade-in help guidance says the final value is generally applied to the original payment method. If that is not possible, Google may issue Google Store credit instead. Store credit is not cash, so it should be valued at less than a cash refund if you do not expect to buy more Google hardware.
Which watches should you check?
Run the estimator for the exact device rather than relying on a headline maximum. Relevant categories may include:
Rank #3
- The new Google Pixel Watch 5 offers a smarter way to a healthier you.[1,2]; Designed for Gemini Intelligence, get proactive help, and personalized insights from Google Health[3,4]; watch is compatible with Android devices only; not compatible with iOS devices
- Precision-crafted to do it all: The Google Pixel Watch 5 features the domed Actua 360 display with scratch-resistant Gorilla Glass and up to 40 hours of battery life[1,5]
- Metrics that matter: Advanced sensors help you stay ahead of your health and wellness; and Google Pixel’s most accurate heart rate tracking is fine-tuned for your activity[6,7]
- Understand your sleep like never before: Your watch captures insights like the time spent in sleep stages to breathing regularity, then summarizes it all in a personalized Sleep Score[8,9]
- Detects loss of pulse, then calls for help: Pixel Watch 5 is the only smartwatch to feature Loss of Pulse Detection, which can prompt a call to emergency services[10]
- Pixel Watch 3 in 41mm or 45mm;
- Pixel Watch 2;
- the original Pixel Watch;
- Apple Watch Series 10 or another recent Apple Watch;
- Galaxy Watch 6, 7 or 8;
- Fitbit Sense, Versa or Charge; and
- older, Wi-Fi-only or damaged watches.
An Apple Watch Series 10 was used as a representative device in an earlier Pixel Watch 4 launch promotion that advertised a maximum $350 promotional credit. That was a 2025 offer, not evidence of a current 2026 value. Likewise, Google’s prominent $100 Pixel Watch 4 discount ended August 2, 2026 and should not be treated as active on August 18 without confirmation in the live cart. See Google’s current offers page and the historical promotion terms.

2. Best Buy: a possible lower-price alternative
Best Buy has listed a Pixel Watch 4 at $349.99, shown as $100 below a comparable $449.99 value, with a “Trade in and save” estimator. However, the available listing was not sufficient to establish that the price or a trade-in promotion remained active on August 18, 2026.
Check the exact Best Buy listing and complete the estimator before deciding. Record:

- the old watch’s quoted trade-in value;
- whether the benefit is an instant discount, gift card or other credit;
- online versus in-store requirements; and
- what happens to the trade-in if you return the new watch.
Best Buy can be the better deal if its lower price and trade-in value combine to beat Google’s final checkout total. It is not the current winner based on a stale or recently crawled banner alone. Check Best Buy’s trade-in promotions as well as the product page.
3. Google Fi LTE data: useful value, not trade-in cash
Google advertises two years of Google Fi data for Pixel Watch 4 LTE purchases. This can improve the effective value for an existing Google Fi customer or a buyer who genuinely wants independent watch connectivity.

The displayed offer requires an LTE model and acceptance of Google Fi’s terms, and states that voice calling is not supported under the offer. It is therefore a poor substitute for a direct discount if you do not need watch data or require voice calling.

No current Verizon, AT&T or T-Mobile Pixel Watch 4 trade-in offer was verified in the available research. Do not assume a large carrier discount exists until the carrier shows it in a current first-party offer page or checkout flow.
Best Value

When a carrier does advertise a deal, distinguish among:
- Instant discount: reduces the purchase price immediately.
- Monthly bill credits: spread the benefit over a set period.
- New-line requirement: may require activating a watch line.
- Port-in or upgrade requirement: can limit eligibility.
- Plan lock-in: credits may stop if you change plans or cancel service.
A $300 bill-credit offer is not equivalent to $300 off today if it requires an expensive plan for 24 or 36 months. Add the required service cost and compare the total against buying the watch outright.

5. Should you sell the old watch instead?
Private resale is the main alternative for owners of recent Apple Watch and Galaxy Watch models, but it cannot be declared the better dollar option without a current quote for the exact model and condition.
| Trade-in | Private sale |
|---|---|
| Simple and usually tied to the new purchase | Potentially higher proceeds and more control over price |
| No buyer messages or marketplace dispute | Requires listing, communication and negotiation |
| Credit may be available quickly, subject to inspection | Payment may be delayed by shipping, fees or buyer acceptance |
| Lower effort, potentially lower value | Marketplace fees, shipping, insurance, fraud and returns reduce gross proceeds |
Sell privately when the realistic net proceeds—after fees, shipping, insurance and your time—comfortably exceed the retailer’s confirmed credit. Trade in when the difference is small, you need a quick and predictable transaction, or you value avoiding buyer disputes.
Trade-in preparation checklist
- Back up any data you need.
- Unpair the watch from your phone.
- Remove Apple Activation Lock or equivalent account protection.
- Cancel or remove the watch’s cellular service.
- Factory-reset the device.
- Confirm that it powers on and matches the condition submitted.
- Photograph the screen, case, sensors and accessories before packing.
- Package the watch securely.
- Keep the shipping receipt, tracking number and delivery confirmation.
- Mail it before the stated deadline.
Failure to power on, an account lock or passcode, water damage, a cracked display, a swollen battery or missing required components can affect eligibility. Do not ship a potentially unsafe battery device until the vendor gives you appropriate instructions. For an LTE watch, make sure it is removed from the carrier account; for an Apple Watch, disable Activation Lock; for a Galaxy Watch, remove the relevant account connection before resetting.
Which route fits your watch?
- Pixel Watch 3 owner: Start with Google Store’s estimator, then compare Best Buy’s live quote for the identical Pixel Watch 4 size and connectivity.
- Apple Watch owner: Check Google’s quote, but also obtain a net private-sale estimate. Recent Apple Watches may have stronger resale demand.
- Galaxy Watch owner: Compare the Google and Best Buy quotes with a marketplace price after fees; recent models may justify the extra work.
- Damaged or non-working watch: Expect a sharply reduced quote or rejection. A private sale is only sensible if the device has repairable or parts value.
- LTE buyer: Include the two-year Google Fi data perk only if you value the service and accept its limitations.
- Buyer who dislikes store credit: Prefer a confirmed refund or a private sale; do not value Google Store credit as cash.
- Maximum-return buyer: Compare the trade-in quote with realistic net resale proceeds, not a marketplace’s highest asking price.
Bottom line
For a straightforward purchase, check Google Store first: it is the best-confirmed Pixel Watch 4 trade-in path, but the final amount is device-specific and subject to inspection. Then run Best Buy’s estimator for the same watch configuration; it could win if its advertised $349.99 price and retailer credit are still live. Choose private resale only when the expected net proceeds clearly outweigh the convenience of a direct trade-in. Treat the expired $100 Google discount, the historical $350 maximum and any unverified carrier promotion as unavailable unless the current checkout explicitly confirms them.
