Third generation of Wise's wave-inspired Diving 300M: a 44mm titanium diver with a scalloped bezel ring, a domed sapphire crystal and a "Brain Coral pattern" dial, sold on straps. Each listing is one dial code (DTB331, DTB431, DTB831); Wise's text gives only "Brain Coral pattern", so the blue, green and orange colours are read from the product photos. Movement: Wise writes "Cal 8315 Automatic", 21,600 bph and about 60 hours, without naming the maker; the caliber number and figures match Miyota's 8315, and the photos show a date at 4:30. Titanium grade is not stated. Dimensions from Wise's text (the DTB831 page omits the 15.8mm thickness) and Wise's case drawing, which shows the side view including the crystal and a solid caseback; the drawing's caseback text reads "Stainless steel", so it appears to be shared with the steel Gen 2. Bezel: the drawing and photos show 15/30/45 numerals and a lumed pip at 12 (lume photo); whether it rotates, and in which direction, is not stated. Lume is Wise's "C3 X1 (Blue and green)"; the lume photo shows green markers and blue hands and pip. Crown type and weight are not published. The DTB431 and DTB831 listings offer Made-to-Order or Ready-to-Ship at the same price; all three were orderable on 2026-10-25. Release year from the listings (June 2023, published October 2023).
