From video reviewers

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

Grand Seiko SLGW007

Grand Seiko SLGW007 owners and reviewers praise its compact 38.6mm x 9.95mm Evolution 9 case and the textured "Moonlit Birch" dial, described as moody, elegant, and captivating.
