Greetings Watchexchange, Up for sale is an incredible dynamic vintage Seiko ceramic tank 7430-5230 from May of 1985. This lovely tank has a textured dial and beautiful titanium nitride case. The case is a hardened ceramic with a surface hardness of 1200Hv making it essentially scratchproof. As a result, the watch is in outstanding condition. The watch comes on an aftermarket 20mm crocodile leather strap and measures approximately 31*35mm (Allow for slight errors in measurements due to the lack of calipers, the watch is pictured on a 6.5" wrist). The watch has a lovely onyx crown. The 7430 movement is fully operational and keeping time within its intended accuracy. A japanese engraving on the caseback indicates the watch may have been a long service award. [Timestamp ](https://imgur.com/a/58jyvML) The watch is priced at $159 shipped via UPS, paid via Zelle or Wise.
