Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
Owners widely praise RGM watches for their American craftsmanship and special, unusual designs, with one owner finding the tele and tachy scales brilliantly done and perfectly colored. The 38.2mm case size contributes to a diminutive appearance for some, while others find the brand's designs mesmerizing and aspirational. Owners report that RGM watches wear well and garner compliments, with watch experts recognizing the brand's quality. On balance, owners and reviewers rate RGM Watches Model 455 Classic Chronographs highly for its unique American craftsmanship and vintage-inspired dial details.
