Men's Seiko 7549-7010 Quartz Tuna
This is a 7549 that runs like a champ and is in amazing condition. Let the pictures be your guide. The only thing changed on it is the crystal was replaced with an AR (anti-reflective coating). Some scratches on the shroud consistent with age. Please see pictures for best description.
(One thing I noticed when I saw the pictures was that there are a few particles of dust under the glass. Whoever swapped the crystal must have missed this).
