Limited Edition – authentic East German watch history revived

This is not just a watch – it is a piece of German industrial and horological history.

With the UMF-RUHLA Caliber 13 “Ruhla at Heart”, a legendary movement returns to the wrist: the original UMF quartz caliber 13, developed and produced by the Ruhla watch factories during the GDR era.

Historic original movement – brought back to life

At its heart beats a true time capsule:

• Original NOS movement (New Old Stock)
• Carefully stored for decades
• Now tested, revived and used for the first time in new watches

These movements remained untouched for decades – and are now ticking again. Not as reproductions, but as authentic originals.

A rare piece of history that can hardly be found today.

“Ruhla at Heart” – tradition from Thuringia

The roots of the Ruhla watch industry date back to 1862.

Over generations, Ruhla became one of Germany’s most important watchmaking centers – producing millions of timepieces and pioneering numerous technical innovations.
