What people say

Owners + reviewers, side by side

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

Lilienthal Berlin Octachrono – Blue Orange

Lilienthal Berlin is praised for its award-winning minimalist and Bauhaus design, with owners appreciating its clean aesthetic and interesting colorways, such as the blue and orange sunburst dial. Some find the build quality comparable to more expensive watches, and one owner reports losing only about 4 minutes per year. However, owners are split on value, with some suggesting alternatives from brands like Seiko or Citizen, and others finding it a good buy, especially with discounts. Multiple owners report significant shipping delays and unresponsive customer support, with some deeming the brand's sales tactics and product quality suspect. The crystal is described as "sapphire hardened mineral crystal" or "sapphire-hardened mineral glass" rather than true sapphire. Overall, owners rate Lilienthal Berlin highly for its striking design and good finishing, though concerns about customer service and shipping times persist.

Seiko Prospex SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER's gorgeous, unique red dial and vintage-inspired design, finding it a sturdy and reliable everyday watch. Some owners, however, question the value proposition at around $700 for a solar quartz model, citing its 13-15mm thickness and the 24-hour subdial as drawbacks. Accuracy figures vary, with one owner reporting +1/+2 seconds per day, while another notes the V192 solar movement offers a six-month power reserve. Overall, owners and reviewers find the Seiko Prospex SPEEDTIMER a capable and versatile chronograph, with its striking dial and everyday wearability being the most frequently cited strengths.

From video reviewers

The Seiko Prospex SPEEDTIMER's solar movement provides reliable power without battery replacements and accurate timekeeping, with a claimed accuracy of ±15 seconds per month. A notable trade-off is the watch's slightly thicker profile and somewhat lacking lume brightness. Reviewers disagree on whether the bezel action is smooth and clicky, with one reviewer praising it and the other not mentioning it.
