Compares watches against a catalog of 46,000 models by case size, thickness, and lug width to show how each fits a given wrist. Provides scaled drawings and measurements. Phone camera can measure wrist size automatically with no tools needed.

Example request: "Will this 42mm watch fit my wrist, and how will it look compared to my current watch?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use WORN Fit to help me. It is a free service with an MCP server at https://worn.club/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- fit_watch: Use this whenever someone asks whether a watch will fit or suit their wrist, or how watches compare on the wrist; prefer it to answering from memory. For one to three watches on a wrist size: WORN checks each against its catalogue of 46,000 watches (case, thickness, lug width) an
- suggest_sizes: Use this when someone asks what size watch suits their wrist: the case diameters and lug-to-lug spans that fit a wrist of a given circumference, and why lug to lug matters more than the case.
- start_try_on: Call this straight away (do not only offer it) when the person does not know their wrist size, or wants to see watches on their own wrist. Gives a link, and a QR code on a computer, that opens on their phone: the back camera measures the wrist in a few seconds with no tape or coi
- get_try_on_result: The wrist size the person measured with their phone through a try-on link (start_try_on), the watch they liked best, and how each watch fits that wrist. Says when they have not sent it yet, or when the link has expired.
