What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Alsta Superautomatic

Owners and reviewers widely praise the Alsta Superautomatic's excellent retro 70s dive watch design, with a strong connection to the movie Jaws. The contrasting case finishes and dial build quality are well-regarded, and the comfortable Tropic strap is a plus. However, the watch is considered egregiously overpriced at MSRP, with some noting a Seiko NH35 movement and stamped clasp as disappointing for the price. The bezel lacks lume, and one reviewer criticized the bracelet's poor detailing and less crisp machining. The Alsta Superautomatic is seen as a fun summer piece around $500-600, oozing 70s cool. On balance, owners and reviewers rate the Alsta Superautomatic highly for its vintage-inspired design and Jaws movie connection, despite significant price concerns at MSRP.

From video reviewers

The Alsta Superautomatic offers excellent value for its price point. Reviewers noted that the lume is on par with Seiko.

Ralf Tech WRX ELECTRIC BLACK

The Ralf Tech WRX ELECTRIC BLACK is noted for its striking domed sapphire crystal and good lume, with owners appreciating its quality feel and exclusivity as a limited edition. The perlage-polished aluminum dial is a standout feature rarely seen on affordable dive watches, contributing to its functional, tool-like design with large luminous hands and markers. However, the watch is described as huge and heavy, and the small crown can be difficult to manipulate, while the large buckle on the leather strap may irritate some wearers. A reviewer also expressed skepticism about the brand name and noted the watch site is only in French. Overall, owners and reviewers find the Ralf Tech WRX ELECTRIC BLACK to be a unique tool watch with a distinctive dial, despite its substantial size and some ergonomic considerations.
