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.

Grand Seiko SLGW005

The Grand Seiko SLGW005 is lauded for its faithful recreation of the 1968 45GS, featuring a desirable double-signed dial and a beautifully finished case adhering to the Grammar of Design. It is powered by the new 9SA4 manual-winding, high-beat movement, offering an 80-hour power reserve and a mean daily rate of -3/+5 seconds. Owners consider it a "gloriously perfect" and "pure and elegant expression" of Grand Seiko's strengths, with one owner preferring its creamy dial over a more pronounced beige found on other models. Overall, owners and reviewers rate the Grand Seiko SLGW005 highly for its elegant design and impressive high-beat movement.
