I personally recommend the most cost-effective perpetual calendar watch worth buying is IWC’s rose gold perpetual calendar, which is classic, practical, and beautiful. It can usually be won within 300,000.This hairspring was invented by Rolex in 2000, and is often referred to as 'blue niobium hairspring.' The diameter of this hairspring assembly is less than 1 cm, but it has excellent performance and can effectively resist the impact of temperature and watches. At present, this hairspring is basically used in Rolex watches.
