AVI-8 Sabiha Gökçen 24-Hour Automatic Limited EditionvsLongines ULTRA‑CHRON CARBON

Owners are divided on the AVI-8 Sabiha Gökçen 24-Hour Automatic Limited Edition's design, with one calling it "horrible" and not a collector's item, while another finds it more meticulous than previous models, though still too busy and large. The watch features an NH34 movement with a 24-hour GMT function, measuring 42mm in diameter and 16mm thick. Owners also question the high resale prices. On balance, owners express significant reservations about the design and value proposition of the AVI-8 Sabiha Gökçen 24-Hour Automatic Limited Edition.

The Longines ULTRA‑CHRON CARBON is praised for its lightweight composite case and unique "Batman" aesthetic, with its 5Hz movement widely noted for exceptional accuracy. Owners widely report the high-beat movement is the cheapest 5Hz option available. Some owners find the non-rotating bezel a relief, while others consider it a deal-breaker, noting the watch is no longer a dive watch. On balance, owners and reviewers highly rate the Longines ULTRA‑CHRON CARBON for its cool, lightweight design and the exceptional accuracy of its 5Hz movement.
