The Swatch USA Olympic Team 1996 Watch (model ref. GZ150U) is made from the following materials: Case: Clear plastic (typical Swatch material for that era, lightweight and transparent). Strap: Silicone (listed in the seller’s description, flexible and translucent). Crystal (watch face cover): Plastic (acrylic), not mineral or sapphire since Swatch from that time mostly used plastic crystals. Buckle/Clasp: Stainless steel (visible on the strap). Movement: Quartz, visible through the transparent back. So overall, it’s primarily plastic and silicone, with some metal parts (movement, buckle, hands). The surface has a brushed silver tone, which reflects light. The hour markers and hands contrast subtly against the silver background. The USA Olympic rings logo is printed in color on the lower part of the dial. Method of Shipment FedEx or Japan Post NOTICE The lot will be carefully packaged and shipped by FedEx or Japan Post.
