SEIKO Seiko 5328-0020 Hand-Winding Silver Dial Men's Watch Small Second Mechanical Watch Brand: SEIKO Movement: Hand-winding watch Case diameter: Approximately 32mm Case thickness: Approximately 7.2mm Number of jewels: 17 jewels Frequency: 21,600 bph (6 vibrations) Daily rate: Approximately ±5 seconds (actual measurement) Overhauled: April 2025 Accessories: Main unit, overhaul statement, warranty (OH store until October 2025) Condition: The crystal has a slight scratch at the 10 o'clock position. The case also has only minor scratches when magnified, with no noticeable large scratches. The strap and buckle are aftermarket. *All images are taken of the actual watch. *Serial number is hidden. This watch is equipped with SEIKO's "5328," commonly known as "Swiss Seiko." SEIKO is now a manufacture that produces everything from the dial to the movement in-house, but this is a very rare model equipped with a movement manufactured by Fontainemelon, a long-established Swiss mechanical manufacturing company. While the ladies' model with the number 6 missing is sometimes available, this men's size is a rare model even among them. The design is a user-friendly small seconds silver dial, but it has thin vertical stripes in the center, creating a two-tone shading effect depending on the light. This is a recommended piece for those looking for a rare watch in SEIKO's history.
