Sealiner GMT
Model History
Sealiner is the collection with which Cvstos turned its tonneau case toward a nautical theme, offering a watch the brand itself describes with the image of "a yacht for the wrist". The reference is not purely aesthetic: navy blue or deep light-blue dials, cleanly designed indexes and hands, and the presence of the GMT function — intended for those tracking multiple time zones, such as those who live aboard or travel frequently — explicitly evoke the world of sailing and yachting.
The line's reference model is the Sealiner GMT, available in 41 and 45 mm cases and in various material combinations, from steel to 5N red gold to two-tone versions; these have over time been joined by more compact variants such as the 36 mm Sealiner Thirty6, aimed at a broader audience including smaller wrists, and executions with a case entirely in transparent sapphire, made in limited series.
Alongside the GMT-complicated version, the Sealiner family also includes chronograph executions (Sealiner Chrono) and, more recently, editions made in collaboration with professional athletes: variants that expand the range of available colors and materials without altering the line's underlying approach, and which for that reason remain part of the same Sealiner family rather than standalone collections.

Main Executions
The name "Sealiner" plays on the assonance with the great ocean liners, reinforcing the bond the brand wants to create between this line and the idea of sea travel: a fairly unusual theme in the world of GMT collections, more often associated with aviation than with navigation.
