Mario, in the latest issue of Practical Sailor, they mention that Plastimo Compasses have a sealed bowl and are not considered repairable. That being said, you might drill a very small hole in the top of the bowl, fill the compass and seal it with a caulking material. But be aware that one of the problems you might encounter if you do this is fluid leaking out when it gets hot<from the Maltese sun> and air leaking in when it gets cold.
