Chronoswiss · Delphis Oracle
Strengths
The Oracle’s strength: the change of hour becomes a visible event, while the blue enamel dial rewards attention between those transitions.
Things to consider
A thickness of 14.5 mm and an unfamiliar reading layout call for a fitting: theatrical mechanics will not suit every daily routine.

Strengths
A rare reason to observe a watch for years: the Planetarium brings the scale of the Solar System into everyday life. Black aventurine glass gives that idea a fitting setting.
Things to consider
A 60-hour power reserve demands attention to winding during long breaks. Planetary cycles reward observation over weeks; do not expect fast mechanical animation.
