NOMOS Glashütte Tetra Alpha

Tetra Alpha is a hand-wound movement manufactured by NOMOS Glashütte, introduced in 2010 as a variant of the Alpha caliber adapted for the brand's square Tetra case. The movement is produced in-house at NOMOS's Glashütte manufacture and remains in production, powering both the Tetra and Tetra Neomatik models. This represents the Alpha family's expansion beyond the brand's traditional round case designs into the geometric Tetra line.
