What people say

Owners + reviewers, side by side

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

Lorier Hyperion SII Skyward

Owners widely praise the Lorier Hyperion SII Skyward for its comfortable, thin, and light wearability, with one owner noting a perfect case width and another highlighting its 10.7mm thickness. The bi-directional GMT bezel is described as decent for its price, and the movement is considered fine and accurate, making it a low-key travel watch. The bracelet is also noted as well-made and finished for the price. On balance, owners rate the Lorier Hyperion SII Skyward highly for its comfortable wearability and value as a mechanical GMT.

Sugess Seestern S434 Pro Diver

Owners widely praise the Sugess Seestern S434 Pro Diver for its impressive finishing and craftsmanship at its price point, highlighting the applied indices that play with light, excellent BGW9 lume, and attractive color options. Specific positive notes include the domed sapphire crystal, short lug-to-lug, and on-the-fly clasp adjustment. However, some owners report quality control issues such as misaligned bezels or indices, while others with V2 models experience no such problems. Caveats include slight bezel back play, light AR coating on the crystal, and a clasp that could be smoother, with one owner desiring a color-matched date wheel. On balance, owners rate the Sugess Seestern S434 Pro Diver highly for its exceptional value and build quality, particularly the dial finishing and lume.
