For Sale is my Citizen NK5010-51X, the Tsuyosa Small Seconds. Purchased new and had it less than a month. Worn maybe a dozen times. Still in like-new condition. 9.5/10. 40mm case. Sapphire. Tool-less, quick release spring bars. Leather strap for this watch is available from Citizen. Online descriptions of this dial describe the dial color as army green, but this is not accurate. I would describe the color is copper/bronze. Asking $299. No tax. Free Shipping in the CONUS.
