Authentic Seiko Tank ownership starts here—even if you’re shopping strictly for parts or a repair project. This listing features a genuine Seiko Tank men’s watch head, model 4130-5250, with a 27mm rectangular stainless steel case and a silver dial in a classic silver-tone finish. The piece carries the unmistakable Tank silhouette that vintage Seiko lovers seek, but note that it is sold for parts and restoration only.

Key details that matter for parts and repair

• Condition: Used with visible scratches on the case and crystal. The movement is not currently running, and a fresh battery will not restore function.
• Movement: Quartz. Because the unit isn’t working, this watch head is most valuable as a donor for replacement parts, not as a ready-to-wear timepiece.
• Dial and aesthetics: Silver dial with non-numeric hour marks retains the line’s timeless look, offering usable dial components for a restoration project or as a display donor.
• Case and construction: Stainless steel, 27mm rectangular Tank profile—compact, sturdy, and suitable for salvaging the case, crown, or crystal if you’re aligning a restoration with other donor components.
• Brand and model: Seiko Tank, 4130-5250. A respected vintage reference for Seiko enthusiasts and collectors who curate separate parts from multiple pieces.
• What’s included: The watch head as described. No bracelet, no box, and no working guarantees. This is sold strictly as parts/repair material.

Who this is ideal for

• Watchmakers and skilled hobbyists working on a Seiko Tank restoration or part-sourcing project.
• Vintage Seiko collectors assembling donor pools for case or dial swaps in similar Tank references.
• Parts enthusiasts seeking a genuine 27mm rectangular Tank component to complete a custom build or repair workflow.

How this piece solves real needs

Rather than acquiring a complete, functional watch, you gain access to authentic Seiko Tank components that are increasingly scarce for certain references. Use this head to salvage:

• Salvageable dial elements and hands for compatible Tank models.
• Case and crystal components for cosmetic restoration on a similar reference.
• Movement parts or a donor crown and hardware to refresh another project.

Practical tips for buyers

• Verify compatibility with your Seiko Tank family project by matching case dimensions (27mm) and rectangular geometry to your donor pieces.
• Assume cosmetic limitations—scratches and potential refinish work will be necessary if you’re aiming for a visual match with a completed restoration.
• When sourcing repairs, this piece can complement other parts you already own, reducing overall restoration time and cost.

If you’re assembling a precise Seiko Tank restoration or building a curated parts collection, this 4130-5250 Seiko Tank head offers an authentic, vintage foundation. It’s a targeted choice for specialists who value genuine references and want to preserve the Tank lineage in their own terms.
