The measurements of this large case watch are 55 x 51.2 x 16.9mm, and it weights about 70 grams. The rivet bezel design and anti-skid wide buttons give it a strong, long-lasting appearance.

The mixture analogue and digital face, dubbed the "three-eyed" beast by others, is a wonderful fusion of new age and conventional technology, with embossed indexes and a very 3-D app.
