Reading list: Can I fit prescription lenses into first copy watches?
No, you generally cannot fit prescription lenses into first copy watches. Watches, including first copy watches, have fixed watch glass (the clear cover over the dial) that is not designed to hold corrective prescription lenses like glasses or contact lenses. The glass on first copy watches for men or first copy watches for women is made to protect the watch face and is not adjustable for vision correction.
If you need vision correction, use proper prescription glasses or contact lenses rather than trying to modify the watch glass. Altering the watch glass can damage the watch and void any support or warranty. When you buy first copy watches online, choose models with clear and scratch‑resistant glass so they stay easy to read, but do not expect them to replace optical lenses for vision purposes.
