Despite measuring in at 48mm wide and having an unmistakable wrist presence, this timepiece sits comfortably on the wrist. It does bare much resemblance to the Seiko Tuna, as it brandishes a similar stainless steel knurled bezel, which allows the uni-directional bezel to be easily turned. Also present on the dial is a lume pip at the 12 o’clock mark to increase legibility. Also similar to the original Tuna model is to the green metal shroud that protects the case. This bestows the watch with a tank like appearance, as well as the feeling that it would be able to take on some military-grade impact as well. Flashes of vibrant red are instilled through the pushers that are present on the left side of the watch. Likewise a screw down crown sits neatly besides the 3 o’clock mark.

The Dial:

The watches were one of the first analog-digital dive watches with a digital LCD display seen right at the top of the dial. For 2019, the Arnie is back with a few subtle updates that do little to diminish its tough and manly appeal. The dici-analog lay out is neat and effective. The digital time is displayed at the top of the dial. Whilst the remains space of the dial is used to display the analog time. It consists of lume coated indices that are very subtly engorged that adds a nice level of texture to the dial. Similarly, the polished silver batton styled hands add to the legibility of the watch. The electrifying orange seconds hand is hair-like thin, but because it is set against the black dial it is certainly noticeable and certainly welcomed.

Much depth is provided through the two step rehaut design, which makes the dial of the watch appear as if it sitting way beneath the hardlex crystal glass that protects it.

The Strap:

The strap is made from reinforced silicon bands that are able to withstand harsh operating environments. Also, the military green strap has a ribbed design, which is a subtle reminder of the watch’s background. Seiko’s attention detail is present in the form of the wave design that is embossed on the strap. It fastens using a standard buckle.
