Selling my early 2023 Tuna in close to new condition an easy 9/10. Battery good for the next five years. This newest version also comes with a curved sapphire crystal instead of the Hardlex and with added super hard coating for additional durability. If you haven't tried a Tuna you owe it to yourself to try one, I was skeptical for a long time but once I tried one I was a convert. With the lungless design these wear much, much smaller than their size would indicate. Wear much better than the MM300 or many other smaller Seiko divers. This is a full kit, inner/outer box, tags and comes on oem bracelet in excellent condition. It was mostly worn on a the green nato which will be included. OAM bracelet has the on the fly adjustment, which is very handy. Currently adjusted for 7.5 in wrist loosely and comes with two more links. The 7C46 mvmt is very high caliber and very robust and accurate movement. It is a (Hi-Tech) multi jeweled movement built with all metal components with extremely "Hi-Torque tolerances and High efficiency". All designed to handle the extremes of deep saturation diving. Easy to find some reviews on it. Only reason I am selling this one is that I have three, I tried the 1000 Tunas as well and they are very nice but much prefer how the 300s wear. Asking $775 USD with PPFF shipped in CONUS Not looking for trades on this one.PM for any more pictures or questions.Lots of references here.
