Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's WatchvsZelos Mako 4

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.

Owners widely praise Zelos' dial finishing, with specific admiration for blued markers and hands, and the unique titanium bezel insert. Reviewers highlight the Mako 4's impressive case finishing and fully lumed ceramic bezel for its price point, noting the boxed sapphire crystal and wavy dial texture contribute to a vintage feel. The Sellita SW200 movement is described as reliable, with one owner reporting accuracy of -0.3 seconds per day. However, the crown can be difficult to grip, and the winding mechanism offers resistance when screwing down, while the watch's height may hinder wearability under a suit cuff. The tropic rubber strap is considered excellent, in contrast to a stiff leather option. On balance, owners and reviewers rate the Zelos Mako 4 highly for its exceptional dial and case finishing at its price point.
