The watch, which is available with either a 41.5 mm or 36.5 mm case, is particularly special. The PET plastic recycling process produces random patterns, meaning no two dials are the same. In effect therefore, each piece is unique. Were not limiting either size, and well keep making them for as long as theres demand. Our hope is that our customers will choose Aquis Date Upcycle and join us in making a daily commitment to reducing the worlds ocean plastic crisis.Beyond the dial, the watches share their architecture with the popular Aquis Date 41.5 mm and 36.5 mm models. Both have a stainless steel case and a uni-directional rotating divers bezel with a scratch-resistant grey ceramic insert.They also have a stainless steel bracelet with a clasp extension system, crown protectors, a screw-down crown and a Swiss Made automatic mechanical movement.
