Second generation of Wise's wave-inspired Diving 300M: a 44mm steel diver with a scalloped bezel ring and domed sapphire crystal. Each listing is one dial code (DS or DSX plus three digits); every code sells as a strap set (black FKM rubber, a free FKM rubber strap matched to the dial and a NATO strap) or the same set plus a steel bracelet, whose SKU adds "S" (DS311S). Movement: "NH35A Automatic, 24 Jewels", 21,600 bph, 41 hours; date at 4:30. Steel grade is not stated. Wise's text gives 44mm and 22mm lugs; lug to lug (51.25mm) and the 15.8mm height (side view including the crystal) are from Wise's Diving case drawing on these listings. Solid caseback with an engraved logo, from Wise's photos. Bezel: 15/30/45 numerals and a lumed pip at 12 (lume photo); whether it rotates is not stated. Lume: Wise writes "Super-Luminova C3 (Blue)" for every code except the DSX421, which is "Super-Luminova C3 (Green)" and glows green in its lume photo; the other lume photos show a blue glow. Bracelet: 3 links per row counted from Wise's photo; its construction and clasp are not stated. Crown type and weight are not published. Status: every Gen 2 listing was sold out on 2026-10-25 and Wise now sells the titanium Diving 300M Gen 3 (2023), so it is recorded as discontinued; Wise does not say so itself. The listings date from February 2021; the release year is not stated.
