This case design was first introduced in the Spirit line and subsequently brought over to the Mechanical line. There are quite a number of variants under the Spirit line including some with Arabic hour markers.
Under the Mechanical line, it has even more variants including the RGB colour models as well as a pink gold and a black out variant.
Here’s a photo review of the pink gold variant – SARB072.
