Averin
History of the line
The Averin Chronograph was born in 2008, the year Union Glashütte became an independent brand within the Swatch Group with its own production in Glashütte. From its debut it stood out for an unusual choice in the town's watchmaking: a square case, in a catalogue otherwise dominated by round cases, combined with a dial featuring a distinctive date display that defined its identity in the early years.
Over the years the line has been progressively simplified: in 2024 Union presented a renewed version of the Averin Chronograph that dropped the old complex date display in favour of a racing-style two-counter layout that is quicker to read. The new piece is fitted with the proprietary UNG-27.S2 calibre, a cam-operated automatic chronograph based on the Valjoux 7750 architecture, with a silicon hairspring and a 65-hour power reserve, housed in a 41 × 41 mm square case with bevelled corners, available in steel (satin and polished) or black DLC.
Described by the trade press as one of the most "polarising" offerings in the Union catalogue precisely because of its case shape, the Averin remains the brand's most explicitly sporty line together with the Belisar, and periodically receives limited editions linked to motoring events such as the Sachsen Classic.
Technical specifications
Main versions
The UNG-27.S2 calibre powering the Averin Chronograph shares the architecture of the Valjoux 7750, but adds a cam switching device and a silicon hairspring: a solution that allows Union to offer an automatic chronograph certified "Made in Glashütte" while staying in the most accessible price bracket of the Swatch Group.
