I have wondered about this many times and never heard it discussed much. I recently saw this video from Patek and just wondered what SOP is with most Watchmakers.

There have to be times and locations where watches are more likely to be closed with high humidity in the air or other potential for contaminating the case environment.

Here is the video for anyone interested. In this step, the watch is heated before being finally sealed. See step 6.

Like canning veggies heating case will cause a vacuum when case cools down. Very cool

Brushpup · 13 October 2012, 11:46 PM

So how is this normally dealt with Rik? Any special precautions taken upon closing a case?

I watched a Rolex watchmaker here in Arlington Texas open and reseal my watch many times and did not use this type of device. I don't recall seeing such device either. Cool idea, but not sure of benefit if watchmaker's facility is environment controlled.
Is a vacuum a good idea for a watch??
However, I have used low heat oven/environment chamber to dry devices. If your environment is not controlled, a heated device could create condensation when it cools.

Ambient temperature low humidity is all that's needed vacuum would be difficult on a watch to maintain for extended periods with crown openning and closing all the time. Just my opinion. Rikki

I use a vacuum soft tip brush instead of just blowing any dust around the room to suck out the case and back and dust on the dial. I have airhandlers but there's always a little something in the air that knows just when to land on the dial when recasing so you have to move fast sometimes to ensure nothing floats in at the last moment.

Thanks for the update. I've always wondered about someone just opening a watch to check it out or whatever, then closing up without regard to contaminating the environment inside.

That's always a concern especially when there's crud around the case back. You should always use a soft bristle brush to clean the surrounding case back of debris then blow it away or wipe clean before openning any watch because that crap just naturally falls into your movement. So as they say last one who opens it gets stuck with the check if something goes wrong. Rikki
