DB25T Zodiac
Table clocks or grandfather clocks, pocket watches and now wristwatches: the very essence of this horological culture graces the dial of the DB25T, notably in the aesthetic work on materials, the engraving and the light effects, but also and above all through consistently demonstrated miniaturization technology. Further enhancing this intensely private performance visible exclusively on the back of the watch, its tourbillon 30’’. Limited edition of 20 pieces.
