Ask yourself though, do you really need a 300m pressure test, or do you just need to know that it is not overtly leaking. You aren't going to take it much deeper than 30 feet.

I wouldn’t bother with a dive < 30 ft. I dive regularly to 80-100 ft and occasionally to 170-250 feet. Obviously not 1000 ft, but enough to need more than the dry test.

They also didn’t offer to change the seals and do the test. They wanted to do a full service. Why do I need a perfectly working movement serviced to get new seals?
