Streamliner PumpThe Streamliner Pump is offered in two versions, each limited to 250 pieces. Its case is crafted from a material rarely seen in watchmaking: forged quartz fiber. Purer and whiter than glass fiber and resistant to UV exposure, quartz fiber can be colored, offering a level of aesthetic freedom that carbon does not allow. Cut into segments, placed in a mold and compressed, it is combined with injected resin before undergoing two successive curing cycles.
