What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Oris Aquis Date Diamonds

Owners and reviewers widely praise the Oris Aquis Date Diamonds for its quality, value, and versatile design, with the glossy dial and ceramic bezel noted for playing with light, and the diamonds offering an interesting contrast. The comfortable integrated bracelet and rubber strap are frequently highlighted, as is the solid build and pleasing crown detail. Some owners find the 36mm size offers a substantial feel, while others note the 39.5mm variant's thickness and the amount of polished surfaces. Accuracy is reported as excellent, with one owner seeing +1 second per day. The Sellita SW 200-1 based Caliber 733 movement has a 38-hour power reserve. On balance, owners and reviewers rate the Oris Aquis Date Diamonds highly for its distinctive design and solid build quality at its price point.

Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's Watch

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.
