is daytona still waterproof if crown unscrewed?

[stussyclie]

let my daytona 116509 be washed while forgotten to have the crown screwed back down.

Is it still waterproof in this case? there should be still few rubber seals to keep water from penetrating inside the case?

[tkerrmd]

Yup

[sleddog]

It is still waterproof, and should be perfectly fine.

For future aquatic endeavors, try to make it a habit of locking down the crown (& pushers).

[Nycturbovr6]

You should be fine but I would lock the screws down before doing any heavy water activities

Its not advisable to fully submerse any Rolex in water with the crown unscrewed but it will still retain some of its water resistance .Now the screw down on the pushers are to stop you activating the chrono if not needed .But the pushers have activated and been tested on forum down at 30m by a French dive team without any problem. And the modern day Daytona with the pushers screwed down has been tested down to 63m 207FT underwater without any problem.This depth would be far deeper that most recreational divers would dive they would limit to around 35m 40m .Even is the pushers are unscrewed no dust or water can get in the case even if fully submersed in water but not wise to activate fully underwater or have crown unscrewed.





Left to right, HEV, Chrono pushers like on Daytona Tudor range,Twin Lock,Triplock.

cool pic Peter, and great info as always

[Andad]

Yes it is.

The pushers for example have no screw down crown but are still waterproof to 100 metres + a good safety margin.

As you can see from Peters pxs the triplock has even heavier duty 'o' rings and are good to rated depth unscrewed.

All seals being in A1 condition of course.

Rolex rate their triplock seal to 500 Bar (5000 metres/>7400psi) and they are not relying on a finger tight crown seal for this.

Very interesting

[crowncollection]

Yes no problem

I called the Rolex office on 5th ave a couple of weeks ago after purchasing a Daytona for myself, and the representative told me that it would "not be a good idea" to leave the pushers unscrewed under water. He said that it would be like leaving the crown unscrewed, which is not advisable. Don't shoot the messenger, I am just passing on the info...

The screw down has nothing to do with the water resistance its just there to stop activating the chrono feature unnecessarily.If you look at diagram the pusher is screwed down see the cap between the o/ring seals.Now look at the twin lock and triplock seals when they are screwed down.But again although it has been tested fully underwater at depth, I would recommend that all crowns should be screwed down when in water.

Fiddlesticks..

There are absolutely no seals or method to seal anything on the pusher nuts, they're just lock-nuts. As to the crown unscrewed, the gasket under the crown is only one of the 3 seals, the others are around the stem inside and any Oyster Rolex is still waterproof to a great degree with the crown unscrewed.

Of course, it is never a "...good idea" to not have all the tools you need engaged for any activity, but unless the inner seals are compromised, no water will enter through the crown or the pushers.

Yep. He has to give the party line.

[ltmgeller]

Very informative thread.

[Rolexpharm]

thanks for the info and diagrams. i think Rolex will always play on the safe side and avoid any warranty issues by sending you the message that the pushers cannot be unscrewed

[Furbo]

You guys can dive with crown unscrewed, I won't , since you could easily press the pusher or hit the crown on something.
