Alsta SuperautomaticvsLongines ULTRA‑CHRON CARBON

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.

Owners praise the Longines ULTRA‑CHRON CARBON for its unique "Batman" aesthetic and lightweight composite case, which weighs only 80 grams. The high-beat L836.6 movement is noted for exceptional accuracy, with one owner calling it the cheapest 5Hz option available. The non-rotating bezel is a point of contention, with some finding it a welcome feature and others considering it a deal-breaker that removes its dive watch functionality. On balance, owners and reviewers find the Longines ULTRA‑CHRON CARBON a surprisingly cool and lightweight watch, with its accurate 5Hz movement being a significant draw.
