Longines · Family: Master Collection
The Longines Master Collection L2.628.4.51.6 is a 38.5mm steel dress watch with a black Roman-numeral dial and a date window at 3 o'clock. It runs Calibre L619, Longines' version of the ETA 2892-A2, automatic, with a 42-hour power reserve. Its current price range, with sources cited, is available further down this page. Its differential: a sapphire display back revealing an ETA-based movement finished and signed in-house by Longines, within a classic aesthetic inherited from the brand's Grande Classique lineage.
Estimated range: €1,703 – €1,767

Longines was founded in 1832 in Saint-Imier, in the Swiss Jura, and is one of the world's oldest continuously operating watch manufactures, with an unbroken registration at the Swiss Federal Institute of Intellectual Property since 1889 for its winged hourglass logo. Today it sits within the Swatch Group, in the conglomerate's upper-middle price segment.
The Master Collection groups the brand's classic watchmaking output: round cases, restrained dials with Roman numerals or applied indices, and simple complications like date or moon phase, in a design language that echoes Longines' mid-20th-century dress watches. Within the Swatch Group, Longines frequently draws on ETA movement bases — the group's own movement manufacture — which it finishes and certifies under its own caliber naming, a common practice at the price tier where the brand competes.
Calibre L619 is exactly that case: a version of the widely used ETA 2892-A2, an automatic movement common across mid-tier Swiss watchmaking for its reliability and relatively slim profile, to which Longines applies its own finishing, an engraved rotor, and regulation before integrating it into the Master Collection.
At 38.5mm, the L2.628.4.51.6 sits closer to the historical dress-watch size tradition than the larger-case trend dominating much of contemporary sports watchmaking, and its sapphire display back lets owners view the movement's finishing despite it being a widely shared industry base.
As with much of Longines' mid-tier catalog, the brand introduces and retires Master Collection dial and size variants fairly often; Cazador does not precisely confirm whether this exact black-dial, Roman-numeral combination remains in current catalog without checking Longines' up-to-date price list.
It's the brand's classic watchmaking line, with round cases, restrained dials, and simple complications like date or moon phase, in a design language echoing Longines' mid-20th-century dress watches.
Cazador has no verified price observations for this reference. We do not estimate or invent a figure without our own PricePoints; this section activates once sufficient data exists.

Longines sits within the Swatch Group, in its upper-middle price segment, and regularly draws on ETA movement bases — also part of the Swatch Group — for much of its automatic catalog.
38.5mm in diameter and 9.5mm thick, a size closer to the historical dress-watch tradition than the larger cases common in today's sports watchmaking.
Up to 30 meters (3 bar), a basic rating consistent with its character as a dress watch rather than a sports or dive tool.
We do not precisely confirm this in this fiche. Longines refreshes Master Collection dial and size variants fairly often; verify against the brand's current price list.
