It takes about 525 lbs of pressure to pull the Oyster bracelet apart...

I was going through some old notes (electronic) that I've made through the years trying to learn more about Rolex watches. This note is from 11th of October 2000, almost eleven years ago, and according to a Japanese magazine (that I do not have...) that were testing pretty much everything, the Oyster bracelet will take 525 lbs before breaking.

Obviously this is the older style bracelets, considering that the quote is quite old.

525 lbs is a lot of pain to your wrist if the bracelet get stuck.

Best,

A

Wonder how much force it takes to snap the spring bar holding the bracelet to the case?

I've heard, correctly applied, a double quarter pounder with cheese can do it.

I think that's great!

Better that it holds, than breaks easily.

I think at 525lbs your wrist will come apart before the bracelet does.

Nice to know my watch will be ok...even if it pulls a hand or two off.

That's amazing. I never would have guessed that it could support the weight of 3 average size men being suspended from it.

Well, the spring bar for adjustments in the clasp has a diameter of 0.9 mm, and that is the same as the current non-lug-holed cases have as lug bars, so if that one can take so much, the pins attaching the bracelet to the case will. Also, the pin connecting the clasp to the first link is 1 mm in diameter.

I remember doing some math on the spring bars to find out when they do break, and as I remember it, the bracelet, as well as the pins are well overengineered. Too much even. I'd rather see the bracelet snap before my wrist do...

Also. I do not remember if the test done by the Japanese included the bracelet only, or the bracelet attached to the watch. Regardless, the figure is amazing.

Best,

A

Well myself have tested the strength of the SD bracelet I had a spring-bar clasp or a lug-pin fail while diving in the Red sea. But in fairness they are not designed to have almost 15 stone dangling suspended, over the side of a boat.It was around 2000 in quite rough sea at the time I was trying to get back into the pick up boat after a dive in the Red Sea there was quite a sea swell.I started to take my fins and BC off when the Egyptian deck hand just grabbed and pulled up my BC and left me suspended by my SD bracelet it was caught on one of the accessory hooks on BC.Its a good job the spring-bar failed one SD lost for ever to the abyss in around 1000ft of water, but I still have my wrist and SD was replaced with insurance..

Mcdonalds of course! The extra grease and fat helps to loosen the bar before it snaps, like WD40. If you squeeze the fat out of a quarter pounder, it ends up weighing like 3 grams. :)

Seriously though, since the springbar is usually the weakest part of the bracelet, I wonder if Rolex would ever consider adopting a screw bar, or even better, a quick change bar system, like Panerai. Cartier/IWC and JLC have them too, I find the quick change bar on my Pam Sub is very strong, unlikely to fail, yet in a second or 2 I can remove it with zero scratches. I doubt Rolex will but I for one would love it.

Well... At least we know that SD may still be ticking today at the shallow depth of 1000 feet!

It has a 48h power reserve not 96360h!

About the 500lbs.

Remember that sudden/accelerated force is different from constant.

I think I could easily with an accelerated and sudden jerk pull my oyster bracelet apart. It might have stood up to 500lbs of force, but for how long? A millisecond?

Well, actually, it's an 8 thousand dollar watch. I'd just as soon spend that 8,000 on something else, like another watch. :)
