SURFACE APPEARANCE- FRONT
From the top, you can see squares like waffle spike shape on both the tail and buckle end. On top of that, there are four rows of “waffle” on each strap, with both designs ending with a triangular prism until the end of the tail and buckle section.

You can also see on the buckle side there are waffle patterns on the middle of the keepers, which gives it a textured look.

From the back you can see at each hole there is a rectangular prism pattern embossed on it, While it looks very nice, it is also functional to provide breathability to the wrists and improve grip during diving. At the end of the tail, you can see a SEIKO and JAPAN text embossed.
