From video reviewers

The HELM Khuraburi offers a rugged, solid build for its price point. Availability is a significant drawback, with the watch being difficult to acquire due to infrequent stock.

Spinnaker Spence 300

The Spinnaker Spence 300 is widely praised for its slim 10.9mm case and 40mm diameter, offering a comfortable and uncommon thin diver design at its price point. Reviewers and owners highlight its value, especially below $350, and its blend of retro design with modern specifications, including a 300m depth rating and a fully indexed bezel.
