Tetra is a modern re-interpretation of the original Armitron’s LED digital watch. It still features the classic design, let’s just say vintage-inspired case with polished gold, silver, and black-plated model. It’s not an always-on display but that cool red digital numbers wait in sleek black sleep mode until you activate it by pressing the side button. Even the strap speaks retro style, it’s nice having a piece of fashion history on your wrist. It’s a water resistance watch for up to 165 feet. [Buy It Here]
