You will need to replace the entire gauge and to do this the top cover will need to be removed from the machine.
The gauge has a long thin copper tube which bolts up to the boiler and the gauge itself is attached from behind with a supporting bracket and nut.
If your machine is an old Giotto classic, youre out of luck for an original replacement, but you can replace the gauge with one from a Giotto premium.
The part will cost you around $50 + around 10 min of technician time if you dont feel confident to do it yourself.
