Lebois & Co Numeral ChronographvsZenith Chronomaster Open

The Lebois & Co Numeral Chronograph 324.497 is widely praised for its 39mm case size, which reviewers and owners find very wearable and well-proportioned, and for its vintage charm derived from elements like a stepped bezel and domed sapphire crystal. Owners and reviewers highlight the beautifully textured, multi-segmented dial with applied indices and blued hands, as well as the case finishing and detail, noting it punches above its price category. The manually wound LC-450 movement is noted for its smooth operation and a 60-hour power reserve, though one reviewer found the telemeter scale legibility suboptimal. Owners are split on the strap, with some finding it subpar and too thick, while others acknowledge its quality. On balance, owners and reviewers rate the Lebois & Co Numeral Chronograph 324.497 highly for its excellent case finishing and dial details 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.
