The Garmin Fenix 6 watch comes in multiple variants.
If you have purchased the 'Pro" version, you may find that the packaging of the product does not have "Pro" written on it.
This is not a cause for concern, as the product is indeed the Pro model.
You can confirm the exact model by comparing the part number that is just above the barcode on the box with the part number on the Garmin Website, as shown in the images below:
