    hiii,
    pressure tested at private watch repair store on this past weekend. According to the slip they gave me it looks to have been done on a Proofmaster M V2. 10, with the following results:

    Test pressure: +3.0 bar
    Maximum deformation: +24.48um
    Tightness value: +0.2 %/min
    Test1 okay

    They recommend to visit certified service center because of Tightness value score. Can I know 'Tightness value: +0.2 %/min' and should I go to service center because of this?

    Thanks!

    I didn't find the right solution from the Internet.
