Question about Samsung Galaxy Watch 8

-Choose size M/L: When purchasing, make sure to select the 40mm case size with the M/L strap size (suitable for approx. 14.5 to 20.5 cm).
-Buy strap separately: If the 40mm version in your desired shop only comes with an S/M strap, you will need to buy a separate strap.
-Alternatively, check the 44mm watch: The larger 44mm model comes standard with the longer M/L strap and often looks more harmonious on a 19cm wrist.

I myself have a circumference of 17, there are still 4 holes free on the bracelet, that's 2 cm, so in my opinion, it will be just borderline!
