You were obviously on a bit of a crusade with it. The First Crusade, I assume.

Well played!

My C65 crown has accidentally pulled out while pulling my hand out of my pocket, a couple times. I personally wouldn’t risk swimming with a watch without a screw down crown, because I might accidentally bump it or catch it and pull it out. That would be on me.

The crown on mine caught on a pocket as well, it happened a couple of times quite soon after I got the watch, so I have never fancied taking it into water. There was a lot of discussion on this a while back and, despite CW resolutely maintaining that it was safe to take into water if the crown was fully pushed in, they have since changed all C65s (I think) to screw down.

Interestingly, the first watch they ever produced (C5 Malvern Auto) has a WR of 50 m, so no good for swimming. And yet it has a screw down crown.

If not then it reminds me of those really cheap Chrono watches where the Chrono dials are just for show. I hope that's not the case with CW.

I didn't see this answered so I thought I would jump in. CW dive watches are in fact legit dive watches. The first thing I did was to take mine down to about 90 feet but to be fair, I have the C60, not the C65. I find the "water resistance" rating thing on watches to be a bit misleading/confusing .The C65 is rated at 15 ATM so I would think it should be good down to 10.

I think that my push crown Dartmouth is a BRILliant watch. I am happy enough to wear it whilst FLOUNDERing around in the sea.

I just ensure that the crown is pushed in before PLAICEing my hands underwater and submerging. A DAB with a fingertip to ensure good to go has become an automatic response when approaching water.

Manipulating a crown can be RUDDy difficult if you have CHUBby fingers. I believe RAYmond Weil had a good solution.

Similar problem, condensation on the glass after shower.... it is tbe second time it has happened.. contacted CW and waiting response.. I tested for water resistance with Calypso wet test and was fine no leaks up to 12Bar circa 120mt. As

I am not sure if is the crown (not screwed in crown design) getting water in?

Unfortunately I bought it on eBay with no papers and the seller after sales has not been helpful even with some basic information.. I love the watch the design, the vintage lume the bracelet is a fantastic skindiver.

Welcome. Do please visit the Member Introduction section and tell us about yourself.

At a guess, your watch is probably about five years old or nearly (no papers, I see), but it sounds as though you have pressure tested it. I had one of these and never actually risked it in water because of the crown, which popped open a couple of times on the edge of my pocket.

I have a couple of watches I’m perfectly happy to swim with, but I never wear them in the shower, unless it’s one of those cold rinse showers at the beach.

Thanks for the feedback, you are right is a five years old and although went under a Calypspo wet test the crown is the weaked link. Last night I pull out the crown and here I have it now... so sad no alternative that to take it to CW for repair. I will ask if possible to retro fit a screw down cwron as in you tube a first blue model was fit with it. But I take on board your comment, this is not a watch to swim or take a shower.
Thanks for your good advices.

That is definitely bad news.

It is also important to remember that the inside of a watch isn't a vacuum. There is air and water vapor present inside the case. Rapid transitions in temperature can cause the crystal of a watch to fog. Here is an example from Mark at Long Island Watch. At about 16:44 he takes a factory fresh Seiko SKX (an ISO certified diver meaning that each individual watch is tested at the factory for compliance) and gets the crystal to fog by putting an ice cube on the dial. I am not saying this is what happened (you didn't list too many details) but I could see taking a watch from a shower (high temp) and then going to work on a winter day (low temp) would cause the crystal to fog. The crystal will retain the heat longer than you would think.

Either way, your crown issue needs to be sorted.

Here is the vid for reference:

condensation on the glass after shower....

The seals on watches are intended to keep out liquid water, not water vapor. Showering in an enclosed space will generate a lot of water vapor, especially if hot water is involved. If your watch is in the same room (or being worn), some of that water vapor will likely find its way in past the seals, and will then condense when the watch cools off.
