Product information "Schallmauer Automatik - Old Radium Nr. Zwo - "Tweede Pelle" leather strap light brown with white stitching"

In the matte black of the night and the warm glow of Old Radium lies the legacy of the great pilot’s watch tradition. Our Old Radium Nr. Zwo unites the clarity of bygone times with the resilience of modern engineering – a dignified symbol of adventure, precision and timeless elegance.

The Schallmauer Automatic is equipped with the Swiss precision movement Sellita SW510BHa, which is appreciated for its quality worldwide. To maintain the highest quality standards, the rotor and date disc are specially finished for us at Sellita in La Chaux-de-Fonds.

This watch has an exclusive limitation of 100 pieces. Each watch has an individual engraved limitation number.

The 316L stainless steel and scratch-resistant, double anti-reflective sapphire crystal (also on the caseback) are perfectly crafted, extremely durable and will outlast anything.

Of course, the red date must not be missing. It sets a decisive accent on the fascinatingly functional dial and has already been chosen as a trademark by our watch friends.

The ceramic bezel with contrasting numerals gives the sound barrier a very special shine.

Even in night use, because the illuminant Super-LumiNova BGW9 or Old Radium - Grade A , lets the hands, numerals, indices and the zero marker shine for a long time.

Good to know

Eine wunderschöne Uhr, die nicht nur durch ihr Aussehen sondern auch in der Technik besticht!

Ich wollte schon bei der ersten Edition eine Schallmauer „old Radium“ ergattern. Der zweite Versuch hat geklappt. Das besondere der Schallmauer „old Radium Nr. Zwo“ ist die wunderschöne Kombination des klar gestalteten Zifferblattes mit dem cremefarbenen Indices und natürlich dem roten Farbtupfer des Sekundenzeigers abgerundet mit der roten Datumsscheibe ist diese Uhr ein „Hingucker“ . Auch technisch bestens ausgestattet mit dem extra für Vandaag überarbeiteten Kaliber von Sellita SW510BHa elaboré ist die Schallmauer eine unbedingte Kaufempfehlung. Viel Uhr zu einem wirklich leistbaren Preis.
