This material has exceptional physical properties. Lead-free, it is lighter and of higher quality than other glass crystals. Its low dispersion properties (with Abbe numbers around 60) and low refraction (1.52), combined with high clarity, make it perfect for creating high-precision and durable glass objects.The casebackThe finely engraved caseback celebrates the adoption, for the first time in 1884, of the 24-time zone system as the global reference time system based on Greenwich Mean Time. Around the depiction of the terrestrial globe, the major cities of the world are listed next to their respective reference time zones, allowing the wearer to set the time in a traditional way, thus preserving the charm of a purely mechanical precision instrument.
