Seiko
Authorized dealer
Asking $800–$1,100
Suggested ceiling ~$850
Catalog MSRP $950 sits within the observed range, no discrepancy. Also confirmed this reference has a JDM alt-reference, SARX123 (same physical watch, Seiko's Japan-domestic vs export naming split) -- recorded via alt_references to avoid the SSC915/SBDL099-style duplicate-row bug (ADR-0005).
Secondary / used
Asking $600–$800
Suggested ceiling ~$650
One like-new full-set listing found at $805 (close to new price, not representative of typical used discount) -- used the more general $200-300-below-new guidance instead for a more realistic watch_only-tier range. Lower confidence than AD pass since this is inferred from a range statement, not multiple concrete listings.
