DSSD depth rating?

[Mrhenish]

My eight year old was mesmerized when I told her that my watch is waterproof to 50 meters (gmt iic). Then I showed her the DSSD dial on the internet. Her question was very serious: “Dad, do you think that watch can go one inch deeper than 3,900 meters?” Does anyone know? This might be my chance to get her to like watches.

20% deeper is what Rolex supposedly tests their watches to.

Thank you Bas

I was always led to believe it was 10% for all models except the Divers which are 25%.

Edit.
That's strictly in relation to Rolex standards.

^^This is what I thought as well. It basically means you can go snorkeling with non diving models. So any “Can I swim with?” question is a safe and resounding “yes”.

thats not Rolex though right? Thats the ISO certification requirement for all dive watches. 25% more than whats on the dial whatever that number is right?

OK, now I'm curious as to where this comes from ...

Rolex tests their watches with more pressure they officially can take. Almost twice their rated depths ?

[Rashid.bk]

Can't remember the literature but I've read it a few times...25% more than what the dial says.

And all other Rolexes are water resistant to 100m...none are 50m. Interesting enough, Rolex advertised in the early days as waterproof watches, then they modified this because of legal reasons to water resistance for a time...now I notice they are back to using the term waterproof, sweet.

Edit:
Straight from Rolex.

STRINGENT WATERPROOFNESS TESTING
Defying the elements
All Oyster Perpetual models are equipped with the Oyster case, providing the movement with optimal protection against water, dust and shocks. Before being shipped, every Oyster watch is immersed in water and subjected to a pressure 10 percent greater than that found at the depth to which it is guaranteed – 25 percent more in the case of divers’ watches. This means that every Rolex Oyster is not just capable of resisting at least 100 metres of water pressure. It has actually done so.

They may test them to there stated depth rating or over, but one thing is for sure no man or even superman will ever use these high rated depth watches to max rated depth in water.Fact there have been more men to have gone to the moon than have dived past 300M wearing just scuba.

ISO 6425 divers' watches standard:

-water resistance standards to a minimum of 100 metres (330 ft) depth rating
-The required 125% test pressure provides a safety margin against dynamic pressure increase events, water density variations (seawater is 2% to 5% denser than freshwater) and degradation of the seals.

https://en.wikipedia.org/wiki/Water_Resistant_mark

So it applies to all watches that are certified dive watches as the minimum standard, its not a Rolex internal safety margin.

That's it precisely

page 10:
"To guarantee water resistance to the extreme depth of 3,900 metres (12,800 feet), Rolex tests every single Rolex Deepsea that is made in a specially designed 1.3 tonne tank. The stainless steel hyperbaric tank, which is cast
in a single piece, simulates the pressure at 4,875 metres (16,000 feet) below sea level, some 25 per cent greater than the depth indicated on the watch dial."

All, thanks for the info. My daughter thinks it is cool this watch goes so deep underwater. Good to get a kid excited about watches. Maybe I can get her to sell my wife on a WG Daytona to replace my 116500 she wears!
