Yeah it's the dial/bezel I think. The turtle is a pretty unusual shape… the lug holes are almost under the bezel. It's a chunky boi in width and height but that short lug to lug and the crown at 4 makes it pretty wearable. But it still looks pretty chunky.
The 40 Shark Diver is actually 2 mm longer lug-to-lug than the new Turtle. 49.2 mm vs 47.25 mm according to the internet.
