The Freezer Might Have Unfogged My Seiko 6309-7040 Diver

I love my new old Seiko 6309-7040 Diver but I have had some problems with fogging that had been killing me. It is always so sad when you have a perfect, badass, chunky Seiko diver that is fogged up — diving watches, even classic watches from the 70s, should probably be water-resistant. It got fogged up, then I put it away and used my other fancy diver.

After a couple months, the steel bracelet of my other diver broke, so I went back to my Seiko 6309-7040 Diver — and the fogging was gone for months. Sadly, I adjusted the time and it fogged again. I have been struggling with the fogging. I tried to dry out the watch in the oven and it worked until the watch got cool, then it fogged again.

Here’s the solution — and it might be unintuitive, but it works! Unscrew the watch to make sure it can breathe. Then, throw the watch into the freezer! There isn’t any place in the house that is drier than the ice box.

Why? Well, because all the water turns to ice, so the watch dries out and all of the vapor leaves the watcha and take to the rest of the box. So far, I removed the watch from the freezer, quickly adjusted the time and then put it on my wrist. So far so good.

So, if you have a problem with your dive watch or any other watch and there’s water in the watch and you’re getting all fogged up, give the freezer a try. You need to make sure your screw-down winding mechanism is unscrewed; otherwise, you’ll just freeze the water inside the watch.

So, I know you’re tempted to put the watch on top of the radiator or in over at a very low temperature, it doesn’t work as well as bringing the timepiece below zero. The watch is now down to body temperature and the watch it still clear! I will let you know what I discover — to see if it really works.

I love this watch very much and I want this classic tool watch — it is really iconic and probably one of the best, most innovative, dive watch ever produced, with the famous and very cool.

Who knows.

I think that if the watch doesn’t maintain its dryness, I will need to find myself a watchmaker or watch repair guru to give me some proper help.

Anyway, if you have any sure-fire ways to dry out a watch, please let me know because I am still not completely certain that this watch is completely clear of humidity.

I will try to give you a report in about 24-hours as to how this all worked out (crossing fingers).
