Seestern's "Series: S406-2", sold on Sugess's store as two listings, S406-2.01 (green bezel) and S406-2.02 (black bezel), both with a white dial and a checkered minute track in the bezel colour. It shares the SUB300T's (S406) case and bracelet specs but has a rotating bezel with a coloured 60-minute insert instead of the Doxa-style steel bezel, and a lume dial. Brand specs: 316L case with brushed, polished and sandblasted finishing, 42mm without crown, 46mm lug-to-lug, 13mm thick, 20mm lugs, flat sapphire with five layers of inner AR, signed screw-down crown, 200m, lumed date wheel, NH35A, beads-of-rice steel bracelet tapering 20 to 18mm with a milled clasp offering 4 micro-adjust positions (how they adjust is not stated). The store calls the dial "LUME DIAL (Non-radiation Tritium lighting tubes patent)"; tritium tubes are radioactive by nature and the lume photos show the whole white dial glowing evenly, like a luminous-paint dial rather than tubes, so it is recorded as a fully lumed dial with no tritium claim. The 60-minute scale, lumed bezel markings and lumed hands are from the product photos. Bezel action, insert material, weight and lume grade are not stated. The store's "compare at" prices are not recorded.
