The glossy ceramic bezel also adds to its shiny appearance. On balance, owners and reviewers rate the Vaer G5 Meridian GMT highly for its true GMT functionality and value.
The Miyota 9075 true GMT movement is consistently praised. Reviewers noted the 39mm case size and classic proportions as a strength. No shared weaknesses were identified.
