Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its slim 12.3mm case and 39.5mm diameter, making it a wearable dive watch. The automatic Seiko 6L37 movement is described as having a 45-46 hour power reserve, with one reviewer noting an accuracy of -10/+15 seconds per day. The watch features a box-shaped sapphire crystal and 200 meters of water resistance. However, its price of A$4,650 is considered high for its specifications, and one reviewer questions Seiko's continued reliance on the 62MAS design. On balance, reviewers find the Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation to be a functional and refined dive watch, though its value proposition is debated due to its price point.

Zelos Mako 4

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.
