Start with your watch’s Settings > About screen and look for the model name or model number. If the watch won’t turn on, check the paired phone app, a manufacturer-documented marking on the watch, or its original box. The exact menu and marking location depend on the brand and software version.
Know which identifier you need
A model name or model number identifies the watch’s product family or version. A serial number identifies an individual device. An IMEI identifies cellular equipment and appears only on cellular-capable models. Garmin also uses a 10-digit Unit ID, which is different from its serial number. If a repair, support, or carrier form asks for one specific identifier, provide that type rather than substituting another.
For example, Google says a Wi-Fi Pixel Watch has a serial number but no IMEI, while an LTE model has both. Apple says the IMEI is available only on GPS + Cellular models.

Samsung Galaxy Watch
Open Settings and look for About watch. On some older models, the section may be called Gear info > About device. Available information can include the model number, serial number, and—on cellular models—IMEI. Samsung says, “Available screens and settings may vary by watch and software version.” See Samsung’s instructions for finding the model number, serial number, and IMEI on a Galaxy Watch.
Garmin watch
On many Garmin watches, open Settings > System > About to find the Unit ID. Garmin distinguishes that 10-digit ID from the serial number; its support guidance describes the serial as a nine-character string of letters or numbers, without spaces or dashes. Some Garmin watches also show a product name in the device information. Menu labels can differ by model. See Garmin’s guidance on finding a serial number or Unit ID.

Check documented markings on the watch
- Apple Watch: Remove the band to inspect the band slot. Apple says Series 1 and later have a serial number there; the first-generation Apple Watch has the serial engraved on the back.
- Garmin: The serial number may be on the back of the watch or under the band.
- Pixel Watch: Check where the band meets the case. Google says LTE models have the serial number on one side and IMEI on the other; Wi-Fi models have only a serial number.
These locations are model-specific. Remove a band only if needed to inspect a documented marking, and don’t assume a marking gives the model number if it shows only a serial or IMEI.
Look at the original box
If you still have the packaging, inspect its product label. Garmin specifically lists the box as a possible location for the serial number. A serial number is not automatically interchangeable with the model number, so confirm which identifier you have.

Choose the next step based on what you can access
| What you can access | Where to look | What to expect |
|---|---|---|
| The watch powers on | Settings > About, or the brand-specific equivalent | Usually the most direct documented route to the model information; the available fields vary by brand and model. |
| The watch is paired to a phone | The manufacturer’s companion app | Apple and Garmin document app-based ways to view device information. |
| The watch will not power on | Manufacturer-documented case or band markings, then the original box if available | May provide a serial number or other identifier rather than a model name or model number. |
| None of these routes identifies the model | The manufacturer’s official support site or manual, searched by product family | Menu names and marking locations vary; there is no established single cross-brand database that translates every serial number into a model. |
When the instructions don’t match your watch
This guide covers Apple Watch, Samsung Galaxy Watch, Garmin watches, and Google Pixel Watch; it is not a universal menu map. Settings and physical marking locations can change between generations, software versions, and connectivity variants. For another brand—or if the listed path is missing—use that manufacturer’s official support page or manual for the product family. If you contact support, tell them the watch’s brand and any identifier you can read, and specify whether it is a model number, serial number, IMEI, or Unit ID.
