The **Tudor Pelagos 39 ($4,600)** would add a **lightweight, high-performance titanium dive watch**. 3️⃣ **Expand complications** – A **GMT or chronograph** would improve the **Complications Metric**. The **Hamilton Khaki Aviation Converter GMT ($1,800)** would add **dual-time functionality**. --- ### **Downsizing Advice** 📉 **Seiko Alpinist SPB197J1** – While **historically relevant**, this watch has the lowest **Rarity and Movement scores**, and its **compass bezel functionality is niche**.
