The size and feel is lighter and smaller than the PloProf. The Planet Ocean wears a little smaller and lighter but has a a larger and easier to read dial. All three have the advantage of adjustable by the user bracelet. This for me is a great advantage while traveling in different climates. I do love them all and always have a hard time deciding what to wear and when. The Ultra Deep is just a nice solid feeling watch to wear on a daily basis.
Thank you. I am 5’ 11” and 185lb my wrist is 7” 3/8” most of the time. Sometimes a little larger. The Ultra Deep is a very comfortable watch to wear, sometimes I wear it on the inside of my wrist so as not to bash things with it.
