3. If the position is not right, do not use the purple light (ultraviolet light) first, you can adjust the position of the calendar crystal, if there is excess adhesive overflow, wipe it off in time.
4. After confirming that the calendar crystal is placed in the correct position and no adhesive overflows, irradiate it with a purple light (ultraviolet light) for about 15 seconds.

Precautions:
The above reference step uses UV shadowless adhesive (ultraviolet adhesive), which is transparent and traceless after drying.
If the position of the calendar crystal is wrong, don't light up! Before illumination, it can be adjusted at will, and the adhesive is non-sticky. After lighting the lamp, the adhesive will solidify and cannot be adjusted! If the glue overflows, you can wipe it off before illumination. It will solidify after been illuminated. You can only scrape off the overflowed adhesive bit by bit with a cutter or wipe it off with alcohol.
