The Tissot PRX 35 Powermatic 80 Stainless Steel - Yellow Gold / Silver takes a 11 mm strap: measure between the lugs and that is the only number you need. A dress watch by proportion: a slim leather strap, plain or lightly stitched, keeps the line clean. With a 35 mm case and 100 m of water resistance, a strap of medium thickness keeps the balance. Automatic movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
