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.

Marathon Steel Navigator SSNAV-D Auto

The Marathon Steel Navigator SSNAV-D Auto is praised for its durable construction, featuring a sandblasted steel case with improved lugs, a bi-directional bezel with excellent action, and 100m water resistance. Owners appreciate the constant visibility provided by self-illuminating tritium gas tubes and the precision of its ETA F06.412 quartz movement, which offers accuracy to about 10 seconds per year. The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.
