Reminded me of vintage Tudor Blue Snowflake Subs. The blue is more navy in color than the Pelagius, almost grey-blue? Even the markers look more creamy than white.
The size (39 mm, relatively thin) and weight with bracelet make it feel very light and easy to wear.
I have the original BB 58 in black and I like this color more. Maybe because it is different (I only have one other blue dialed watch, an IWC PPC).
