Duke Oskar

    • The Duke Oskar is one of three models in our aviation themed Duke Collection. With its striking white textured dial, customised butterfly clasp and the popular Swiss ETA 2824-2 automatic movement at its heart, the Duke Oskar sets a new level of refinement and precision finishing.

      The Duke Oskar features BGW9 lume on the hour, minute and seconds hand and on the hour markers on the dial ring, a customised rotor on the exhibition caseback and a double domed scratch resistant sapphire crystal.

      Each timepiece has been individually hand assembled and is presented in a luxury wooden presentation box with a Certificate of Authenticity, booklet and microfibre cloth.

    • The Duke Collection: Setting the Time

      The Duke Collection movement is the Swiss ETA 2824-2 automatic and hand wound movement. It features a date complication with a date window at the six o'clock marker.

      The crown provides three options for hand winding the movement, setting the date and adjusting the time.

      A - Winding the mainspring
      The watch can be manually wound by winding the crown clockwise while in the “A” position.
      Wind your watch 15-20 times until the second hand starts to sweep naturally.

      B - Adjusting the date

      To set the date wind the crown clockwise while in the “B” position.

      C - Adjusting the time

      While in the “C” position the crown can be wound clockwise or anti-clockwise to adjust the time.
