The Lorus Sport Military Quartz RXN81DX9 takes a 20 mm strap: measure between the lugs and that is the only number you need. We list 37 straps in that width. A field or pilot watch at heart, it suits canvas, nylon and matte leather more than polished calf. With a 38 mm case and 50 m of water resistance, a strap of medium thickness keeps the balance.
