IWC Schaffhausen Iw3716 Portugieser ChronographvsZenith Chronomaster Open

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.

The Zenith Chronomaster Open is widely praised for its refined dial aperture showcasing the El Primero 3604 movement, its manageable 39.5mm case size, and the intriguing display of its 5Hz caliber with 1/10th-second timing capability. Owners and reviewers appreciate the El Primero movement's sturdy nature and the hypnotic view of its fast-beating escapement. However, some find the exposed balance wheel aesthetically polarizing, with opinions split between appreciating its kinetic action and viewing it as a "hole in the dial." Minor drawbacks noted include polished surfaces and a lack of bracelet micro-adjustment. On balance, owners and reviewers rate the Zenith Chronomaster Open highly for its wearable size and the technical display of its high-beat El Primero movement.
