The jet-black dial provides a striking backdrop for silver-tone applied index markers and oversized painted Roman numerals. Luminous material on the hands and hour markers enhances visibility, while a small seconds sub-dial at 6 o’clock introduces additional detail. At 2 o’clock, a large double-date window provides a prominent calendar display, and an additional hour display at 9 o’clock indicates the second time zone. Ceramic pushers on the left side of the case allow the regular hour hand to be advanced or reversed for convenient dual-time adjustment. The overall design balances classic Roman numeral styling with modern functionality.
