Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Dumoreau Monopusher Chronograph for its thinness and attractive finishing on the manual-wind Sellita SW510 movement, with the blue dial variant noted as a limited edition feature. One owner finds the £1,250 price tag too high, seeking alternatives in a lower price bracket. Overall, owners appreciate the Dumoreau Monopusher Chronograph's refined finishing and wearability, though some question its value proposition at the current price point.
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.
