What people say

Owners + reviewers, side by side

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

Lorier Olympia SII

Owners widely praise the Lorier Olympia SII for its excellent value and vintage aesthetic, highlighting the robust Seiko NE88 movement and crisp chronograph pushers. The 39mm case is noted for wearing well, with its layered design effectively managing the 13.8mm thickness. Some owners prefer the hesalite crystal for its aesthetic, while others would like a sapphire option. The bracelet is described as functional but can be a hair nipper. Overall, owners rate the Lorier Olympia SII highly for its execution of a vintage chronograph at an accessible 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.
