1. Case:

   • Material: Stainless steel with a polished and brushed finish, giving it a premium, yet everyday wearable look.
   • Diameter: 40.5mm — a versatile size that works well for both smaller and larger wrists.
   • Thickness: 13.1mm — a moderately thick case that provides a solid presence on the wrist without feeling too bulky.
   • Water Resistance: 100 meters (10 bar), which makes it suitable for everyday wear, including swimming, but not recommended for diving.

2. Movement:

   • Caliber: 6R15 Automatic Movement — This movement is a workhorse from Seiko, known for its robustness and precision. It is part of Seiko's higher-end automatic calibers.
   • Power Reserve: Approximately 50 hours when fully wound, which is excellent for a watch in this price range.
   • Accuracy: The 6R15 movement offers a relatively good accuracy range of 25 to -15 seconds per day, though this can vary slightly depending on usage.

3. Dial:

   • Color: Blue with a sunburst finish, which gives it a beautiful effect under different lighting conditions.
   • Markers: Applied silver-tone hour markers that are minimalistic but clear. The markers are filled with LumiBrite, Seiko’s luminous paint, for readability in low-light conditions.
   • Hands: Dauphine hands for both the hour and minute, with a slender second hand. All the hands are coated with LumiBrite for enhanced legibility at night.
   • Date Display: Positioned at the 3 o'clock mark, with a white background that blends seamlessly into the dial for a clean and balanced design.

4. Glass:

   • Sapphire Crystal: The SBDC201 is equipped with a sapphire crystal, providing scratch resistance and clarity. The glass is slightly domed to enhance the vintage aesthetic and adds to the overall durability of the watch.
