AVI-8 Sabiha Gökçen 24-Hour Automatic Limited EditionvsSeiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's Watch

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 Seiko Prospex Marinemaster 1965 Heritage Diver's Watch is praised for its faithful re-creation of the 62MAS design, with reviewers noting improved wearability due to smaller case sizes (38mm to 40mm) and updated bracelets. Specific models feature a stainless steel case with super-hard coating, ceramic bezel, and a tool-free extension system on the bracelet. Accuracy figures vary, with one model rated at -5/+10 seconds per day and another at -10/+15 seconds per day, powered by movements like the Caliber 8L45 or 6L37 offering 72-hour or 46-hour power reserves respectively. Some reviewers point out drawbacks such as an unsigned winding crown, a lack of tool-free micro-adjust on the clasp for certain models, and a secondary GMT function on one variant. The price point, ranging from $2,800 to $3,600, is considered high by some, especially when compared to other Seiko or Grand Seiko offerings.
