1. Are these genuine Audemars Piguet screws?
No. These are generic aftermarket replacement screws, not manufactured by AP, but sized specifically for Royal Oak Offshore 26078.
2. Do these fit the eight visible front bezel screws?
No. The dimensions (3.6mm head diameter) are typically for inner or auxiliary bezel screws, not the larger decorative front screws. Confirm your screw position and size.
3. How can I ensure they will fit my watch?
Remove your original screw and measure overall length, thread diameter, and head diameter. If they match 3.83mm / 2.91mm / 3.6mm exactly, they will fit. Note that different screw positions on the 26078 may have different sizes.
4. What is the quality? Will they rust?
Made of polished stainless steel with good corrosion resistance for daily wear. Avoid prolonged contact with seawater, chemicals, or strong acids/bases.
5. Should I use threadlocker when installing?
For bezel retaining screws, a low‑strength threadlocker (e.g., Loctite 222) is recommended to prevent vibration loosening. Apply only a tiny amount on the threads. If unsure, have a professional watchmaker install them.
