Citizen Rhythm Date, a hand-wound watch. This watch was manufactured in the 1960s. It's a mechanical, hand-wound model with a calendar function. It's from the Citizen Homer lineage, developed to compete with Seiko's Lord Marvel, and features a movement developed as a more affordable version. The dial is marked with "Rhytim Date", "WATER RESISTANT", and "JAPAN 1800". Case size: Approximately 33mm. It's a boy's size, smaller than current wristwatches. As it's an antique watch, there is some deterioration and rust. However, it still functions and keeps time well. There are also some scratches on the glass. The band was recently replaced with a new, off-the-shelf band. Please refrain from purchasing if you are concerned, as this is a used item. Dial color: Silver Belt color: Gold Operation: Good Scratches/Cracks: Yes
