Owners widely praise the IWC Schaffhausen Iw3716 Portugieser Chronograph for its legible design and eye-catching dial colors, with the blue sub-dial "Panda" configuration being a particular favorite. The in-house Calibre 69355 movement, visible through the display caseback, is a highlight for many, though one owner describes its decoration as a "facade." Some owners find the embossed numerals less appealing than applied ones, and one owner advises against using the chronograph function due to its loudness and short running time after wear, also noting difficulties with DOA units. Overall, owners rate the IWC Schaffhausen Iw3716 Portugieser Chronograph highly for its striking aesthetics and in-house movement, despite some reservations about the chronograph's functionality and decorative elements.
