SEIKO Chronos 5H23-7D40 Wristwatch Men's 1980s Working This is from my personal collection. It's been at home for a while, and I recently tested it with a new battery. It is currently working correctly. Setting the time with the crown and changing the date and day of the week on the calendar are also smooth. The calendar's automatic switching is also normal. You can select either Japanese or English for the day of the week. The condition is generally good. The case has minor scratches that are not very noticeable, and the condition is good. The glass has a few faint scratches that are barely visible to the naked eye, but it is generally clean. The dial is also clean. The band is an Austrian leather band that I had at home. It was used for display purposes, so there are some wrinkles, but it can still be used. If you are concerned, please replace it. It looks black in the photos, but it is actually navy blue. Details: Case diameter: Approximately 33mm (excluding the crown) Case material: Stainless steel Case color: Silver Lug width: 19mm Caliber: Seiko Cal.5H23A 3 jewels Made in Seiko Suwa factory in 1980 That's all.
