For the design of the Tube watch we teamed up with Dutch Designer Piet Hein Eek. Piet’s unparalleled vision on design and LEFF amsterdam’s raw, industrial and sophisticated approach, came together in an amazing collection of refined yet tough watches. The design of the Tube watch has an iconic ring that functions as the clock’s face. Therefore, you can recognize every LEFF amsterdam watch by this unique characteristic. The gray, steel watch case is made of stainless steel, contains an analogue movement and has a diameter of 42mm. The steel band is adjustable and has a butterfly buckle. This watch is also available in gold and black. The watch contains a Japanese Miyota movement and a glass plate made of Sapphire glass. The details in the crown are cut with a diamond.
