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

Owners widely praise the Lorier Hyperion SII for its vintage aesthetic, glossy black dial, and tasteful text. One owner notes the Miyota 9075 movement and calls it the best GMT under $800. Criticisms include a small GMT hand that is difficult to spot, and one user found the winding action not smooth with significant crown resistance. Overall, owners rate the Lorier Hyperion SII highly for its vintage aesthetic and value.

Yema Navygraf Marine Nationale CMM.10

The Yema Navygraf Marine Nationale CMM.10 is lauded for its vibrant blue dial and bezel, a slimmer 39mm case at 11mm thick, and its in-house CMM.10 caliber offering a 70-hour power reserve. Reviewers highlight the clean, legible dial, blue sapphire bezel insert, and competitive pricing under $2,000. However, the steel bracelet's clasp is noted by multiple sources as rattly and feeling slightly cheap, with one reviewer finding it difficult to open. Accuracy is reported within a range of +5/-3 seconds per day. Overall, reviewers praise the Yema Navygraf Marine Nationale CMM.10 for its attractive design and value proposition, tempered by minor concerns regarding the bracelet clasp.
