Seiko
Secondary / used
Asking $420–$580
Suggested ceiling ~$460
2020 limited edition (1,964 pieces, discontinued), so secondary_used is the only real channel now -- no current AD/new listings found. Catalog MSRP $850 vs. $420-580 used range is expected depreciation for a 5-6 year old discontinued LE, not a discrepancy. Also confirmed alt-reference SPB131 (international export vs. this catalog's JDM SARX073) -- recorded via alt_references, same ADR-0005 pattern as the SPB465/SARX123 catch above.
