Certina DS-1 Chrono AutovsIWC Schaffhausen Iw3716 Portugieser Chronograph

Owners widely praise the Certina DS-1 Chrono Auto for its elegant design, value, and 100m water resistance. Reviewers highlight its handsome, sober tool-like demeanor and good build quality from Swatch Group. One owner notes the watch is a dressier option than a dive watch, appreciating its Super-LumiNova and AR sapphire crystal. The 42mm case is described as not feeling too large due to a relatively thin profile. Some owners report the included leather strap can be uncomfortable and the clasp sharp. One reviewer noted the date window on a similar model appeared disproportionate and the crystal attracted glare due to a lack of AR coating, though other sources mention AR sapphire crystal. Accuracy figures vary, with one owner seeing +4s/day and another noting the Valjoux A05.231 movement. Overall, owners and reviewers rate the Certina DS-1 Chrono Auto highly for its handsome design and strong value proposition.

Owners widely praise the IWC Schaffhausen Iw3716 Portugieser Chronograph for its legible and handsome design, with specific appreciation for the contrasting blue subdials on a white dial, often referred to as the "Blue Panda." The comfortable blue rubber strap is noted as versatile, though some suggest a leather strap for formal settings. The in-house automatic Calibre 69355 movement is visible through the display caseback, and its column-wheel chronograph actuation is described as crisp and smooth. One owner reported the watch arriving DOA and found damaged parts during attempted repairs, while another noted that the chronograph function should be used sparingly to avoid issues. The 30m water resistance is considered a minor drawback by reviewers. Overall, owners and reviewers rate the IWC Schaffhausen Iw3716 Portugieser Chronograph highly for its attractive aesthetic and refined movement at its price point.
