This is an ete square watch. I purchased it in 2017 at the Shibuya Hikarie store. I think the condition is good. I can attach the quality certificate/instruction manual with my name crossed out. Please let me know if you don't need it. I loved wearing it, so I replaced the worn-out strap with a commercially available one (not ete). I've only used it two or three times since replacing the strap. The battery is dead. Please replace it yourself. Thank you for your consideration.
