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.
