Condition and what this means for you

This item is sold as-is for parts and restoration projects. The case shows wear consistent with prior use, and the crystal is cracked. The movement is non-functional in its current state, and a new battery will not restore operation.

Why this piece stands out for restorers

• Authentic vintage footprint: A genuine Citizen Tank design with a clean white dial and gold-tone rectangle profile that’s recognizable to fans of mid-century-inspired watches.
• Salvage-ready components: Depending on your project, the dial, hands, case shape, and crystal design can provide a faithful donor experience for another restoration or custom build.
• Reference for matching parts: The 6031-K03658 reference helps locate compatibleCitizen ecosystem components or donor movements for compatible vintage variants.
• Ideal for display before and after restoration: Even as a non-working piece, it offers tangible vintage character for a watchmaker’s bench or a collector’s display of restoration progress.

Use cases and who it’s for

• Donor part for restoration projects: Rebuild a nearby or future Citizen Tank with a rectangular, gold-tone motif, preserving the classic silhouette.
• Donor for spare parts: Source usable components such as the case profile or dial layout for other vintage Citizen builds.
• Display/education piece: Demonstrate vintage watch construction, part wear, and restoration steps in a workshop or showroom.

Practical tips for buyers

• Inspect the case geometry and dial alignment when planning a project to ensure a precise fit with your donor parts.
• Use appropriate tools for handling the hard-to-replace crystal and avoid further stress to the case during disassembly.
• Because the movement is non-functional, consider sourcing a compatible quartz movement or using the dial and hands with a different movement platform if your build allows.
• Verify compatibility with other Citizen vintage tank-style watches by reference number 6031-K03658 to maximize restoration options.
