保証書あり (Hoshousho-ari)

保証書あり (hoshousho-ari) means with warranty card or with papers. On Japanese auction and marketplace listings, this phrase in the title or description indicates the watch is sold with its original manufacturer's warranty documentation.

What the Warranty Card Documents

Japanese watch warranty cards (保証書) are issued at the point of retail sale and record the purchase date, the selling retailer, and sometimes the reference number and serial. For JDM watches sold before 2019 when Seiko moved to a global warranty structure, the warranty card confirms the watch was purchased through an authorized Japanese retailer.

For vintage pieces, the warranty card is evidence of originality. A Seiko SARB033 with its original warranty card, dated to within two years of production end, demonstrates that the watch has not changed hands through non-retail channels and that the papers are contemporaneous with the watch.

Warranty Cards and US Resale Value

The premium for 保証書あり varies by reference and age. For modern discontinued JDM pieces:

• A Seiko SARB033 with original box and warranty card typically adds 15 to 25 percent to the sale price versus a no-papers equivalent on US eBay
• Grand Seiko references with full documentation (box, warranty card, swing tag, hang tag) can carry premiums of 20 to 40 percent over unpapered examples
• Vintage Grand Seiko 56GS or King Seiko pieces with period-correct warranty cards are significantly more valuable: the papers confirm authenticity for pieces where dial swaps and component mixing are common
