It has a date display. I removed the SeiyaJapan logo from the dial, Luminous with LumiNova. The sapphire glass, screwed down crown, and the Miyota 8-vibration movement reliability are all the same, providing the exact same performance quality as before. You can enjoy looking through the see-through back. The lug size is 20mm, with many band’s available at that size, allowing for more fun by changing out the band. It comes with three additional straps: one nylon NATO strap and two types of leather straps. --------------------- Thank you very much "Watch Hobby" https://easternwatch.blogspot.com/2017/05/seiyajapan-original-watch-automatic.html Reference "Watch Hobby" Blog: https://easternwatch.blogspot.com/Youtube: https://www.youtube.com/c/WatchHobby/featured
