The most comfortable watch you've ever worn...

[VOT]

Good afternoon, dear colleagues.
After a week with Apple Watch Hermes I realized how comfortable my wrist was after wearing the OP39 daily. This is because of the super comfortable expensive leather strap.
And I asked myself whether there are comfortable watches among Swiss or German brands. Can any of You please share Your experience in wearing very comfortable and light watches?
I have two colleagues, the first has Rolex Daytona and the second UN Marine. Both confidently claim that they will never return to a bracelet (Oyster and President) or leather band after Oysterflex elastomer and Rubber. A week ago I thought it was a joke. But now I think that they may be right.
Need Your suggestions. Many thanks.
