Buy Omega Watches in Switzerland

Omega was founded in La Chaux-de-Fonds in 1848 and has accumulated a catalogue of technical achievements that few Swiss manufacturers can match for breadth or historical significance. The Co-Axial escapement, introduced in 1999 and the first genuinely new lever escapement design to reach commercial production in over 250 years, reduced internal friction and extended service intervals in a way that changed expectations for movement longevity across the industry. Add the Speedmaster's role as the only watch certified by NASA for all manned space missions, the Seamaster's service as the official watch of the Royal Navy's diving operations, and the De Ville's consistent presence at the top of dress watch shortlists, and what emerges is a brand whose commercial success is matched by a technical record that justifies it.
