Gold Oysterquartz question

[timelord]

Has anyone ever been reluctant to buy a gold oysterquartz based on the fact that one needs to open the back every year to change the battery?

Not so much of a problem with a stainless steel Oysterquartz but with gold one being softer, you would expect that the back threads would suffer some wear if not total wear especially on a watch that is some 35 years old with at least 35 openings/&closing.

I was informed at the RSC that the back of an oyster case is closed at a torque of 5 Newton meters which is a heck of a lot of tension on a soft metal such as gold Just a bit worried as one never knows if threads have at times been put on dry without lubricating the threads? Once purchased it would be too late to find out.

My other concern is if the threads are too worn can they be reconditoned/repaired??? My crime is that I just have a soft spot for a gold Oysterquartz. Any thoughts???? THANKS!!
