Market research

Grey market

Asking $604–$604

Suggested ceiling ~$604

full set · single_source

JDM-only reference (no US AD network) so grey-market import dealers (Sakurawatches, japan-select, IPPO Japan Watch) are the effective retail channel, not authorized_dealer. Catalog MSRP on file is $950 -- the $604 grey-market price undercutting that is expected/normal for this channel, not a discrepancy worth flagging.
