Hunter-case watches whose front lid has a glazed aperture and a small chapter ring, allowing the time to be read approximately without opening the case.
Mechanism
Case engineering only: a window and secondary numeral ring are added to an otherwise standard hunter lid.
Typical characteristics
Small enamel or metal chapter ring set into the lid
Aperture aligned with the hour hand
Full hunter opening mechanism retained
Construction and interpretation
The half-hunter, also called a demi-hunter, retains a protective front lid but provides a central aperture through which the hands can be seen. A chapter ring on the outside of the lid permits a reading without opening it. The aperture may be glazed; its construction and condition should be recorded rather than inferred from the name. This is a variation in case design, not a special going train or escapement.
A useful description explains how the hands relate to the outer numerals and whether the window gives a clear reading. Photograph both the closed lid and the unobstructed dial when this can be done safely: the two views document different features. The outer ring, inner dial and hands should be compared for style and fit, but a mismatch requires further evidence before it is called a later alteration. The visibility of the time is the practical distinction from a full hunter.
