Are you looking for a unique watch with character and a rich watchmaking history? This Nivada Grenchen is probably the one for you. Let’s start with the most striking feature: its dial! This Nivada Grenchen has led a wonderful life, having accompanied its previous owner through his daily routine. The dial bears the marks of old moisture stains that have colored the black dial with a faint brown hue. Its Valjoux 92 mechanical movement was thoroughly cleaned and serviced by Pole Horloger in 2025 and is running smoothly (free of oxidation). The crystal is the original one and is in good condition. The hands are also the originals; the hour and minute hands were likely reluminated several years ago. They now display a patina ranging from gray to brown. The inscriptions “Nivada Grenchen,” “Chronomaster Aviator Sea Diver,” and “t Swiss” are visible—markings specific to these early Chronomaster models bearing the reference number 1581 m 8222. The 39mm case is in good overall condition and retains its original shape; the bidirectional bezel is fully functional. We note the presence of the original crown bearing the Nivada logo. We have chosen a brown rally-style calfskin leather strap to complement this chronograph.
