Why is there a watch hole on the sleeve?

It creates a contrast by covering the hand while keeping the watch area on the wrist open. The Grip Watch Hole Long Sleeve from GOYOWEAR is finished in a shape where the sleeve hem covers the hand^[1]. Along with this, a watch hole structure is applied so that the wrist area is exposed^[2]. In functional apparel, a watch hole refers to a cut-out slit made in the cuff so that you can view a smartwatch or running watch screen without rolling up the sleeve.

When exercising in long sleeves that extend down to the back of the hand, having to pull up the sleeve every time you want to check your watch can be inconvenient. With this garment, the watch screen is directly exposed through the hole even while the sleeve covers the back of the hand, allowing you to instantly check your activity status during exercise simply by turning your wrist^[3]. This means you do not need to constantly fiddle with and roll up the sleeve.

hmmm, this construction seamlessly combines the function of covering and protecting the hand with the action of checking your watch while in motion, right at the sleeve cuff without interference.
