New-in-box retail price, single source only -- catalog has no msrp on file for this reference to cross-check against (unlike the sibling Silver-dial C029.807.11.031.00 row, which has $730 MSRP + $880 Watch Pages figure). No suggested buy/sell -- retail range only, same convention as the sibling row. Secondary/used market: no listing found for this exact black-dial reference (only found a pre-owned $479.99 listing for the Silver sibling ref, C029.807.11.031.00 -- not reused here since it's a different dial).

Source note

New row 2026-08-06 -- confirmed as the true black-dial sibling of the existing Silver ref (C029.807.11.031.00): same "807.11" case/material family, only the dial-code segment (.051. vs .031.) differs, cross-verified across 4+ independent listings (Francis & Gaye Jewellers explicitly labels it "Black Dial C029.807.11.051.00"; watchia, watchard, anytimewatches agree). An earlier lead (C029.407.11.051.00) was a different case line ("407" not "807") and was wrong -- not used. lug_width_mm/lug_to_lug_mm carried over from the Silver sibling row (same case, only dial differs) -- lug_to_lug stays provisional per that row's existing caveat. Unresolved: jewel_count, bezel_type, year_introduced, clasp_type.
