Common Questions about the 4300V
Q: Do all the calendar functions work?
A: Yes, all sub-dials (Day, Date, Month) and the Moonphase are fully functional. Note: As this is a replica, it functions as a “Complete Calendar,” meaning you may need to manually advance the date at the end of months with less than 31 days.
Q: Will the Rose Gold plating fade?
A: 8F uses high-quality PVD plating. With normal care (avoiding perfumes/chemicals directly on the case and rinsing sweat off), the color will last for years. It is significantly more durable than gold plating from 10 years ago.
Q: Can I change the strap?
A: Yes, this model features the correct Quick-Switch system, allowing you to swap between the Rose Gold bracelet and rubber/leather straps easily (if extra straps are sourced).
