The design of the tube watch merges Piet Hein Eek’s unparalleled vision on design with LEFF amsterdam’s pursuit for functional beauty, creating an amazing collection of refined yet tough watches. The wristwatches are the latest addition to the tube series, a collection the renowned Dutch designer started creating for LEFF amsterdam in 2014. The precisely cut ring and the high quality 316L stainless steel give this watch its refined, yet tough and industrial character. The tube watch S38 has a 10 ATM water resistance and a sapphire crystal lens. As opposed to the S42, the S38 is lighter and more delicate, making it suitable for a smaller wrist.
