In the case of the case, the SFK001J1 and SFK003J1 are large boys. They’re nicknamed the Sumo in spite of everything. Layered with Seiko’s proprietary super-hard coating, the case measures 45mm in width, 13.2mm in thickness and a really lengthy 51.8mm lug to lug. For essentially the most half, the case proportions match up with the 2022 Sumo, aside from the thickness, as these two fashions are about 1mm thicker. The massive case hugs across the bezel and a facet view of the case exhibits the bezel nestling in, and solely absolutely exposing the bezel grip on the prime and backside of the case. There’s an alternating use of brushed and polish end on the case, with the latter being utilized in an attention-grabbing means. The case sides get a heavy dose of polish because it widens inside the curvy midcase, however its the trace of polish on the inside portion of the lugs that add a special dynamic to the general case aesthetic.
As I discussed above, the Seiko launched final 12 months received an up to date metal bracelet, and that’s what we’ve right here. The design leans extra in the direction of an oyster design, and is refined by means of polish alongside the perimeters of the middle hyperlinks. The bracelet is secured by a locking three-fold clasp and can also be geared up with a dive extension.
So far as GMTs go, that is by far my favourite format. A Diver GMT. Emphasis on the phrase diver, because it’s a dive watch first and a journey watch second, versus a chosen journey watch with added dive watch options. I want to have all of my GMT settings relegated to the dial and ideally would really like some kind of legible 24 hour scale. We get that right here with the SFK001J1 and SFK003J1, plus a cut up tone rehaut which not solely provides extra to the GMT characteristic, however feels very a lot part of the dial design. This leaves the bezel open to utilizing a extra sensible elapsed time bezel. You get each the GMT performance AND a dive watch with 200 meters of water resistance.
