A special collaboration model with the Netflix series "Stranger Things," which will reach its final chapter with Season 5 in November. This timepiece is based on the AQ-800. Drawing from the dual worlds of the story — the familiar reality and the eerie “Upside Down” — the design weaves key elements of the series into every detail. The dial features a pattern of twisting vines, evoking the creeping influence of Vecna. The indexes are rendered in a raised metallic finish using the distinctive Stranger Things typeface, adding depth and character. The case back is engraved with the Stranger Things logo, while the clasp cover bears the number “001” — the tattoo seen on Vecna. The watch comes in special packaging that highlights both the Demogorgon and the signature vines, capturing the threatening forces the characters face throughout the series.This special collaboration celebrates the arrival of Season 5, the final chapter in the Stranger Things saga. Stranger Things Stranger Things is a Netflix mystery adventure series set in the 1980s in the small town of Hawkins, Indiana. The story revolves around the sudden disappearance of a young boy named Will and the appearance of a mysterious young girl named Eleven. A group of young friends are determined to solve the extraordinary mysteries they encounter as they try to protect friends and family. Combining dramatic twists and turns, thrilling tension, and the friendships and exciting adventures of a group of young characters, Stranger Things is full of homages to classic 1980s movies and has been a global megahit since its first season in 2016. The show has sparked a movement so big that it has become a worldwide phenomenon. The final season, Season 5, will be released in November 2025.
