Impactful in RED & GOLD! 200m water-resistant diver's watch! The most convenient? Solar-powered! Limited-time offer! Purchased new on Amazon about a year and a half ago. Unused, but listed as "Like New" due to the instruction manual and box being missing! In excellent condition with no aging or deterioration! The watch itself will be shipped via Yu-Packet Post; no changes to shipping method are possible. It does not have radio wave functionality. Even during transaction communication, I will unfortunately prioritize the first person to purchase. Thank you for your understanding. Shipping may take a few days due to my circumstances. Sorry! Usually ships within 2-3 days! Thank you!
