Maystone Watches has announced that only one unit remains of the Prosperity GMT Serene Skies edition from its current batch. The brand notes that while this specific colorway will return in the future, there is no confirmed timeframe for a restock as the founder focuses on developing new watch models. The Prosperity GMT Serene Skies has emerged as a fan-favorite within the collection, leading to this nearly sold-out status. For customers in the United States, the brand highlights that all orders ship duty paid to ensure no additional fees are charged upon delivery. Potential buyers are also encouraged to explore other available colorways in the collection if the final Serene Skies unit is sold.
