Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Alsta Superautomatic is praised for its excellent retro 70s dive watch design and connection to the movie Jaws, with reviewers noting its contrasting case finishes and comfortable Tropic strap. Owners are split on its value, with some finding it egregiously overpriced at MSRP but a fun summer piece around $500-600, while others acknowledge collector hesitation due to the Sellita SW200-1 movement. The bracelet's execution is criticized for poor detailing and less crisp machining, and the bezel lacks lume. On balance, owners and reviewers appreciate the Alsta Superautomatic for its vintage-inspired design and Jaws movie connection, despite some reservations about its price and bracelet finishing.
The Alsta Superautomatic offers excellent value for its price point. Reviewers noted that the lume is on par with Seiko.
The Marnaut Safe Harbour 100C Safe Harbour Classic 100 (cushion case, multi-subdial complication, applied batons) is praised for its well-executed finishing, signed crown, and domed sapphire crystal. Owners note the 39mm tonneau case is ideal for everyday wear, though its 13.2mm thickness is somewhat concealed by the curved mid-case and sapphire crystal. The glossy lacquered dial with applied indices is a point of discussion, with some finding the busy design and slender handset can make legibility challenging. The initial stiffness of the faux-croc leather strap is noted, but the 20mm lug width allows for easy customization. On balance, owners and reviewers appreciate the Marnaut Safe Harbour 100C Safe Harbour Classic 100 (cushion case, multi-subdial complication, applied batons) for its robust build quality and comfortable wearability at its price point.
