Sellita
Sellita's flagship automatic movement and the most widely used Swiss automatic caliber in production today, having filled the supply gap created by ETA's restrictions on third-party sales. A functional clone of the ETA 2824-2, it is dimensionally identical and shares the same parts compatibility. Available in multiple grades from Standard to Top, the SW200-1 powers watches from dozens of Swiss and international brands.

The community take
Owners talk.
Owners and reviewers praise the Aera Instruments D-1 Diver for its legible, minimalist design, warm 904L steel case that wears smaller than its 44mm size suggests, and impressive lume application. The stamped dial is noted as unique and creating an optical illusion, while the 120-click bezel feels solid. However, some find the 44mm case size too large and the Sellita SW200-1 movement's accuracy range of ±7 to ±20 seconds per day, along with its 38-hour power reserve, underwhelming for the price. The "ghost" date position on the crown is also cited as a minor oversight. On balance, owners and reviewers appreciate the Aera Instruments D-1 Diver for its comfortable wearability and tool watch functionality at its price point, despite some reservations about the case size and movement.
