Pressure testing at home

[Mbalce]

Question - how many of you have your own WR tester? I have 3 older watches, a 1024, a 16013, and a 18038. All run great but they are all over 5 years since last being serviced. Thinking about starting to bring them in but have to prioritize. May also elect to do gasket change only on them depending.

Hate leaving a watch somewhere to get tested and have thought about buying one of the inexpensive (about $200) testers to have at home.

Anyone use one? Are they accurate? Any recommendations for a decent one?

Thanks in advance!
