Seagull 1963 Chronograph Times Edition 40mmvsZenith Chronomaster Open

Owners widely praise the Seagull 1963 Chronograph Watch Times Edition 40mm for its well-finished polished case and beautifully operating signed crown. The 40mm size is reported to wear well, even for those who typically avoid watches over that diameter, and one owner appreciates the visibility of the ST1901 movement through the display case back. Some owners report inconsistent quality control with the ST1901 movement, with one needing repairs within six months due to loose screws. The 40mm moonphase version is noted as having a well-proportioned thickness of 12.7mm. Overall, owners consider the Seagull 1963 Chronograph Watch Times Edition 40mm an iconic and unique starter chronograph, with its value and historical significance being key draws.

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.
