Breitling Navitimer B01 ChronographvsIWC Schaffhausen Iw3716 Portugieser Chronograph

Owners widely praise the Breitling B01 movement for its robustness and accuracy, typically keeping time within COSC standards and often under +-2 seconds per day, with some noting its 70-hour power reserve. The in-house design and solid build of the B01 movement are highlighted, and the Breitling Navitimer B01 Chronograph itself is described as a joy to look at, a stunner with a gorgeous dial. However, some owners question its value retention and find the price prohibitive compared to other models, with one owner noting it is not robust enough for everyday wear at work. On balance, owners rate the Breitling Navitimer B01 Chronograph highly for its accurate and robust in-house B01 movement and visually stunning design.

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.
