Clean, compact, and unmistakably Seiko, it presents a 27mm stainless steel case with a silver dial and non-numeric hour markers—a timeless tank silhouette that pairs well with both formal and casual looks. The model reference is 5E31-5B50, and it’s a Japan-made quartz chronicle in need of some TLC. Note: this is a used item with visible scratches on the case and crystal, and the movement is not currently working. A new battery will not fix it. It’s sold for parts or repair.

Ideal use cases\n- Parts and repair project: Perfect for someone rebuilding a Seiko Spirit Tank or sourcing a compatible 5E31 quartz movement from another donor.\n- Donor for spare components: Salvage the dial, hands, or case for use in other Seiko Tank-style watches.\n- Vintage collection piece for display and study: A hands-on example of Seiko’s tank design from the era, valuable for reference and curiosity.
