Seiko Half Moon Quartz Watch Value Guide

The Seiko Half Moon Quartz Watch is a striking example of 1970s and 80s Japanese design, featuring a distinctive asymmetrical crystal and dial.

What Is Seiko Half Moon Quartz Watch Worth?

The typical price range for Seiko Half Moon Quartz Watch is $50 - $70 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the mineral crystal, as the unique half-moon shape is difficult to replace if scratched or cracked.
• Functionality of the vintage quartz movement and the absence of battery leakage or internal corrosion.
• The preservation of the gold plating, specifically looking for wear or 'brassing' on the edges and strap.
• Originality of the components, including the crown and the period-correct Seiko clasp.

How to Identify Seiko Half Moon Quartz Watch?

• Look for the signature half-moon or 'D-shaped' mineral crystal that creates an asymmetrical silhouette.
• Verify the Seiko brand name on the dial and the 'Japan' origin marking typically found at the bottom of the face.
• Check the case back for the specific movement-case serial numbers characteristic of 1970s and 80s Seiko quartz models.
• Confirm the presence of a gold-plated finish on both the case and the integrated or matching bracelet.
