For a mechanical watch with a perpetual calendar function, if you keep the watch running normally without stopping, you don’t need to adjust it for at least 100 years.

He specializes in mechanical watch appreciation and has unique insights into jewelry, life, culture and art.?At that time, Incabloc was so strong that the brand it had to use had its own trademark on the dial, which angered Rolex and Patek Philippe, so Rolex and Patek Philippe used KIF extensively.
