Movement

Image: The caseback view is also symmetrical. Notice the two large barrels, and the brand’s maritime heritage inspired logo embossed on the crown.

Our Thoughts

Image: Version with blue alligator leather strap (same as header image) is my favourite.

The Nebula 40 Steel Blue Edition is a sought-after colour version of this hours-minutes-small seconds watch. The price – though not exactly affordable – is fair for its unique design and haute horology elements. The Nebula 40 Steel Blue Edition makes a compelling case for a versatile or everyday watch, allowing its owner to appreciate the details of its symmetrical skeletonised movement, both through the open dial and caseback.
