Hello, thanks for looking! Up for sale is the discontinued JDM Seiko MM300 Tuna in excellent pre-owned condition. First owner, purchased brand new in May 2019. No prior service history and the watch is working as it should, though a battery change may be needed soon given the specified 5-year battery life. No visible scratches on the case, but the silicone strap and steel buckle show signs of occasional wear. Perfect for our big-wristed fellas, dive watch enthusiasts, and large-watch enjoyers. Included with the watch are the original box, tags, and papers, as shown in the post. Asking $850, free shipping within CONUS. Payment accepted through Zelle, Venmo, Paypal F&F.
