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.

Hamilton Jazzmaster Day Date Auto

Owners widely praise the Hamilton Jazzmaster Day Date Auto for its versatility as an everyday and business-casual timepiece. One owner specifically notes it felt the best on their wrist after trying multiple options. On balance, owners rate the Hamilton Jazzmaster Day Date Auto highly for its comfortable wearability and suitability for various occasions.

From video reviewers

The watch offers excellent build quality for its price point, with an 80-hour power reserve from the H-40 movement. The 50-meter water resistance is a limitation. Reviewers disagreed on the aesthetic appeal of the date window at 6 o'clock.
