A poetic timepiece

The finesse of the decorations and the purity of the green hand-guilloché dial, radiating in 12 sectors, underline the legibility of the dial, notably through the assembly of annular appliques delimiting the sub-dials and the hour circle. At 12 o’clock, a sphere in palladium and black oxidized zirconium sits in a sky set with gold stars, also incorporating a leap year indicator in a gold pastille in the starry sky at 12 o’clock. The date can be read on a dial located at 6 o’clock, while the windows indicating the day of the week and the month are located at 9 and 3 o’clock respectively.

Unparalleled comfort

The round case of the new DB25QP retains the harmonious lines that contributed to the success of the original DB25QP but is offered for the first time in titanium. This accentuates the practicality and comfort of this timepiece.
