DolceVita 23.30 x 37.00mm Diamond Case / Silver Flinqué Dial / Steel Bracelet

WatchIntel verdict: consider. Good only if judged as a diamond-set jewellery dress watch, weak if judged as a movement-value watch. The official price is multiple times higher than the non-diamond DolceVita because the case is diamond-set. Buyers should not compare it directly with simple quartz DolceVita models or mechanical Longines watches. The fair comparison is against other rectangular jewellery watches with diamonds, not against entry-level mechanical watches.

It uses the Longines Calibre L178. The L5.512.0.71.6 is a jewellery/dress DolceVita quartz watch, not a mechanical-value watch. The movement should be displayed as Longines Calibre L178 only if source-backed; WatchBase describes L178 as Longines' version of the ETA 980.153 quartz calibre, and CaliberCorner describes it as a ladies-size quartz movement. The main value driver of this reference is not movement exclusivity. It is the rectangular DolceVita design, diamond-set case, silver flinqué dial, Longines branding and bracelet execution.

Moderate. Longines heritage and the DolceVita design language add brand premium, but the largest price driver here is the diamond-set case and jewellery-watch positioning. The hype is not scarcity-driven, but the watch should not be sold as mechanical value.

Quartz ownership is simpler than mechanical ownership in one sense, but WatchIntel should not call it universally low-cost. Battery, seal checks and water-resistance testing are straightforward, but the diamond-set case, bracelet, gaskets and brand service route still matter. Use careful wording and avoid fixed service-cost claims.

Moderate to weak liquidity. WatchCharts lists 33 one-year sales volume and median days on market of 134.0, with market price below historical retail. This is not a fast-moving steel sports watch. It is a jewellery-dress Longines whose resale depends heavily on condition, complete set and buyer demand for this exact size/reference.

The overall WatchIntel score is 52/100, combining movement quality, value, hype tax, serviceability, and resale liquidity.

Official Longines pages list 23.30 x 37.00 mm. It is not the 20.5 x 32 mm variant.

Yes. Longines lists the case as set with 46 Top Wesselton IF-VVS diamonds totalling 0.552 carats.

It is a quartz DolceVita. If displaying Calibre L178, cite WatchBase/CaliberCorner and explain that the main value is jewellery-design, not mechanical complexity.

Use dated regional sources only. Longines Netherlands lists €4,750 and Longines Austria lists €4,700 for this exact reference on the accessed pages. Do not show $1,450, which appears to belong to a non-diamond or different DolceVita variant.

Use dated data only. WatchCharts lists estimated market price at $2,744 as of Jun 06, 2026 and historical retail reference around $4,200 as of Aug 2017. Market value varies by condition, bracelet, diamond case condition, box/papers and region.

Yes only if the buyer wants a diamond-set Longines rectangular jewellery watch and accepts quartz movement plus slower resale. If they only want the DolceVita look, the non-diamond L5.512.4.71.6 is likely better value.
