Heritage Collection — Quartz, Blue

Authorized dealer？

Asking $3,100–$3,100

full set · cross_verified

No suggested_buy/sell -- straightforward retail price, not a flip target.

Sources: grand-seiko.com (official brand site) and Exquisite Timepieces (confirmed Authorized Dealer, 5-year mfr warranty), both $3,100, this exact reference, 2026-08-14. Note: an earlier AI-generated search snippet claimed Exquisite Timepieces was pricing this at $2,600 -- a direct fetch of their actual page showed $3,100 flat, no discount, so that snippet figure was wrong/stale and wasn't used.

Grey market？

full set · insufficient_data

Genuine gap, not fabricated -- Jomashop is a real candidate source but I couldn't pull a firm number from it.

Sources: Jomashop confirmed to carry this exact reference (SBGP013G) but price wasn't extractable via fetch (client-side rendering, same limitation hit repeatedly this session). No other discount-authorized reseller confirmed carrying it. 2026-08-14.

Secondary / used？

Asking $1,786–$2,623

Suggested ceiling ~$1,700

full set · snippet_only

snippet_only since I couldn't independently confirm by fetching Chrono24 directly (blocked all session), but three separate pre-owned-labeled listings from the same reference-filtered page corroborate a reasonably consistent $1,786-2,623 range. suggested_buy applies a modest 5% negotiate-down off the low end.

Sources: Chrono24's reference-filtered page for this exact ref (chrono24.com/grandseiko/ref-sbgp013.htm) -- direct fetch blocked (403), figures from search-engine snippet summary of that page: $1,786 (very good), $2,363 (full set, pre-owned), $2,623 (very good). Aggregate stats on that page note 96% of listings include box/papers. Excluded listings explicitly labeled 'New' ($2,168/$2,224) as likely new dealer stock via Chrono24, not genuine used comps.
