Analog-Digital Harmony

Unlike earlier digital hybrids, the D320 emphasizes visual clarity:

• Analog hands are kept slim and unobstructed, ensuring the digital screen below remains visible.

• The digital screen—typically located at the 6 o’clock or 12 o’clock position—shows time, date, and other mode data depending on what function is active.

• When modes like stopwatch or timer are in use, the analog time continues to display without interruption.

• Scroll through over 30 time zones by city code

• Switch between home (analog) and secondary (digital) time displays

• Quickly reference UTC (Coordinated Universal Time)

This function makes the D320 ideal for travelers, pilots, and global professionals.
