Some minor finishing flaws, such as slightly crooked markers and off-center dial numbers, are noted by one owner, while accuracy averages around 5-10 seconds over two weeks.

From video reviewers

The Wave Master GMT's notable feature is its 200M water resistance. A drawback is the rattle of the bracelet.
