Specs from its technical data: 43x49 mm brass case with a 316L steel caseback, brass screw-down crown with a steel core, WR 100, double-domed sapphire with a one-sided AR coating, sandwich dial with applied brushed indexes, brushed hands, Seiko/TMI NH35A, brown leather strap with a brass buckle; the brass patinates. Black, white or brown dial at PLN 1,950 each; the store data's product price of PLN 1,499 comes from leftover untitled options (PLN 1,499 and 1,529) listed after the dial options. The Żabol ("Froggy"), with a dark green dial and bezel, is "a limited version of the Submarine" made for the Polish forum Czwarty Wymiar, sold in its own listings (English and Polish, PLN 1,899, out of stock on 2026-10-31, "last few pieces"), recorded as a variant; it has the same case and movement.
