Régulateur dial
A dial layout separating hours, minutes and seconds into distinct subdials for precise reading.
Explanation
A régulateur dial separates the indications: minutes on a large central hand, hours and seconds on subdials. It imitates the precision regulator clocks of observatories and workshops, where the minute hand was read against the mean-time standard. On wristwatches it is a stylistic tribute to those instruments.
