What people say

Owners + reviewers, side by side

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

Citizen Promaster Air A-T

Owners widely praise the Citizen Promaster Eco-Drive for its value, reliability, and maintenance-free operation. Reviewers note the Citizen Promaster Air Automatic GMT is a large 44.5mm watch with a well-proportioned case and balanced dial, powered by an in-house automatic GMT movement. Concerns are raised about the unframed date window and uninspired case design on the GMT. Some owners find certain models, like the 36mm Eco-Drive, to be very small. The Promaster Air Automatic GMT is priced at $1,125 USD. On balance, owners and reviewers highlight the Promaster's strong value and reliability as its primary strengths.

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.
