Well. For sure I had the same talk until a leak/issue happen a reg can last long time. But everywhere I checked (I edited my previous message) LDS suggests to make after each year or after 100 dives, not many divers make 100 dives per year anyway specially dive tourists who do not run a dive for month and come back in Liveboards without to have their regs serviced. I checked and our "text law" do not suggest to run an annual check.
What kind of tool do you use for internal pressure ?
