Another waterproofness discussion

[burnthesehills]

We often see people asking about non Rolex divers such as the Datejust and whether or not they are "safe" to be in the water. The general consensus seems to be a resounding YES and this is backed up by the literature and guarantees provided by Rolex.

However I have always wondered abut the differences between the Twinlock vs. Triplock design. Certainly having three sealed zones would be better than two. But is this just really overkill for anyone short of an actual diver?

On a side note, I personally think that a Submariner looks perfectly at home on the beach (especially with shorts and flip flops) whereas a Datejust (which I also love) seems a bit out of place.

Well most sub owners would probably never actually dive with them (was a recreational diver and never used mine while diving) so in reality even the Daytona, Sky Dweller, Celini, Daydate, etc can handle most wet situations on real life.

Nothing wrong in my mind to wear a non sport model on the beach !!

The type of crown does not dictate it's waterproofness, nor is it the main seal that might fail.

Not only did the Sub used to have "only" a twinlock crown, the famous "crushed Rolex" ad by Rolex where they take the case down to thousands of feet of pressure and crush the case, the watch was an Explorer w/twinlock, even though it is a Sub ad.

It's not just a catastrophic seal failure and flooding that you have to worry about. You also have to worry about fine leaks that could, over time, cause issues inside the watch. The more seals between the high-pressure water and the case interior the better.

After years of consideration and having my own personal opinions regarding Rolex design, I have come to appreciate and trust their decisions for what type of crown or clasp etc each watch should be equipped with.

If the watch is a diver it gets a trip lock and micro adjust clasp...I think we can agree that for diving purposes these are warranted.

The explorer II Used the thinner twin lock, this combined with the robust crown guards serves to better protect the crown for its intended use.

The Daytona uses the triplock I expect as an aesthetic choice between the two chrono pushers.

I won’t try to explain all their decisions but I have confidence they are made for thoughtful reasons.

Of course there are always exceptions like the (leftover) short hand explorer. This was corrected in a later release.
