Seiko Tank With Sub-Second Dial 1428-5920Maker: seiko Model: quartz 1428 5920 Size: 20x30 Material: plated Glass: hardlex glass Description & Condition Report: A very rare and iconic piece which doesnt need any introduction, and to add a better twist, comes with a sub second dial. The ever iconic seiko tank. Comes with all the cartier esque tank design, with its chemin de fer railroad track, and classic roman numerals. Quite a unisex size in my opinion, but for sure its on the smaller size.
