SEIKO Quartz 7N43 Navy Dial With Calendar Date and Day Function A vintage watch manufactured from the early 1990s to the early 2000s. It's an old watch, butさすがセイコー (as expected of Seiko). It's working perfectly after replacing with a new battery. It's in working condition! The crystal has very slight scratches, but overall it's in good condition (please refer to the images). The dial is navy and beautiful. The stainless steel case has scratches from use (see images). The case size is approximately 3.7 cm in diameter (excluding the crown). The calendar date and day change after 0:00. The date can be quick-set by pulling the crown out one step. The day quick-set is a little sticky, so please advance the 24-hour hand to change it. The date and day are currently set correctly. The hour, minute, and second hands, and the time bars are lumibrite and glow in the dark (see images). The strap is a non-genuine stainless steel strap. The wrist size is approximately 16.5 cm. Fine adjustments can be made on the buckle side. Also, one extra link is included. The battery was replaced with a new one on February 14, 2026. ※ The box in the image is not included! ※ This is an old watch. Please understand. No claims, no returns.
