The water resistance bit is very wrong. The dynamic pressure formula is P = ½ r v² . Let's say you are a superhero and manage to move 36kph (10 meter per second) and if we take salt water (worst case scenario) : P = 0.5 * 1023 * 10 * 10 = 51 150 Pa ( 0, 5048 ATM). You can't make your arm move fast enough to create a non negligeable pressure.

Myth -- The elapsed time bezel on a diver's watch is used to gauge how much air you have in your tank. Elapsed time is not a reliable indicator of air consumption. The rate that air is consumed on a dive varies from person to person and by the level of activity. The elapsed time bezel is intended to indicate your bottom time, or how long you have been subjected to pressure based on the maximum depth of the dive, which determines whether and for how long you need to decompress when ascending.

Regarding "Swiss Made", the Swiss labor costs are substantially higher than those in China. So the watch (sans movement) can be 90% Chinese-made but get the Swiss Made label because the nominal Swiss part costs more than 60% of the total. This seems like the biggest scam in watchmaking.

Hi Jenni, long time watcher and fan, keep up the great content!! I see comments about water resistance thrown around a lot in the watch community so I thought I'd put some numbers to your comments (which are absolutely correct in principle) for everyone's benefit.

Using the formula you correctly quoted, which is for a STATIC object (i.e. no velocity within the submersed fluid), assuming our watch is underwater (and therefore density is ~1000kg/m^3):

Depth rating of 30m (or 3 atm) = 1000*9.81*30 = 294.3 kPa. This is how much pressure the seals in the watch are "rated" for.

Now assuming we are swimming underwater in a pool, say 2m deep, lets also assume that we are moving our arms at 5m/s (~11mph or 18kph, so quite fast), the pressure experience by the watch seals will be:

depth contribution = 1000*9.81*2 = 19.6 kPa (also referred to as static head)
velocity contribution = 0.5*1000*5^2 = 12.5kPa (referred to this as dynamic pressure or dynamic head)

Total = 32.1kPa, or about the equivalent of being 3.2m of water. So our movement in the fluid equates to the equivalent of an extra ~1.2m in depth if the watch were static. Note that the velocity is a squared term, so increases rapidly with velocity. E.g. if you were to fall off a jetski doing 40mph, this would contribute 144.5kPa (0.5*1000*17^2), which is an extra ~15m equivalent of depth.

Hopefully that's useful for people to get a feel for how much movement of a watch within a fluid actually affects the pressure it experiences.

Nice work clearing those up. Had forgotten the water pressure equation from engineering studies in college. Of course the current joke is ‘99.9% of luxury watches never come in contact with any fluid - except champagne!’

Myth 8 . The price of a watch has a direct correlation to its workmanship.

[BrittPearceWatches]

This is why you are the best! Loved this video Jenni! Particularly loved all the chat around in-house movements vs. off the shelf. Everyone went nuts for in-house the past few years, but you are absolutely right! In-house doesn't always = better. Nothing wrong with a tried & true ETA, miyota, etc.!

I bought a fake Rolex in Mexico once. At the time a fake Rolex there was going for a non-haggled list of $30 US. It has a quartz movement and the gold plating wears off within a month or so.
But the one I bought was a stainless steel GMT Master II with a true Swiss Movement. I paid $150 US for it in Tijuana down Revolution some. I sold it to a friend that owned a real one that looked just like it. His Jeweler asked him to bring it in for the challenge of comparing fun. Everyone LOVED it! It's worth it's own value. The jeweler wanted it! Fakes can be fun and they DO have their own value - but never pass it off as real...people have more respect for you if you tell them up front "it's fake." - especially if they already KNOW it's a fake. (usually that will be the REASON they bring it up to you - a test.) Great conversation starter of a naughty trip into Tijuana and the Midnight Express slipping through customs. The switchblade knives and Cuban cigars and the fake Rolex watches. Just TOO fun! Then someone said to me of my trips there and back "You know, there's better paying stuff you could be smuggling and the jail time is the same." I stopped visiting Mexico.

I’m not even finished watching & I can say that this is my favorite video you’ve ever done. I’m enthralled. I liked this video not only because I genuinely love it, but so I can go back & watch it again later. Thank you for the work & research.

I've seen an engineer demonstrate that the instantaneous pressure peaks due to typical human motion in water were still negligible compared to the nominal hydrostatic rating of a watch. I haven't bothered to validate that. I stay on the safe side and just assume anything except a diver is best removed before swimming. And I know that temperature vastly changes a pressure rating - so keep any watch out of your hot shower

So glad to hear that I don't have to worry about over winding my 5000bar 137 jewel Swish made Tuder. One really great feature of this watch is that it is absolutely spot-on accurate -- twice each day!

[dimitriostsiganis]

Hydrostatic pressure equation has nothing to do with dynamic pressure and water flow, which in this case is caused due to swimming. Hence what you need to consider is Bernoulli's Principle, which states that:
As the speed of a fluid (liquid or gas) increases, the lower the pressure it exerts.
In this case water moves relative to the swimmer. So in theory when someone swimms with their watch on (I don't understand why some people do that...), the watch receives lower pressure than if they were just stand and float in the water.

[jabezhane]

I watched some pressure testing that Hydraulic Press channel did. They tested a few cheap watches and some mid range ones. The testing showed all the watches held up to double their depth rating at least. The main point of fail was the case back. They would press inward and stop the hands. Lower the pressure and the watch would go again. Pushing several times past would eventually crack the crystal.

Myth #8- the guy swimming butterfly in the video knows how to swim butterfly. He does not. Absolutely awful technique. Signed, a swimmer.

[BAF]

Myth 8. The Rolex secondary market is recovering strongly since the public letter from Rolex HQ. 😂🤣😂

[JDRichard]

On your comments about over winding of automatic watches. Automatic watches cannot be overwhelmed as the mainspring inside actually slides against the inside wall of the barrel. These main Springs are not permanently a fixed to the barrel wall and so continuing to wind the watch simply causes the main spring to slide more. So, you are 100% incorrect in your description of over winding of automatic watches. This is also true for modern manual wind watches as well, again, to prevent the breaking of the mainspring within the barrel. Love your channel and love your reviews, but this time a correction is needed.

[davidc]

As you know, a watch jewel is called a Stein or stone in German, so no implication that it makes the watch more precious as the word "jewel" might, at least in German. I would say, however, that the number of jewels corresponds to the number of moving parts that need to be protected, and hence correlates to the watch's complexity.

[SB-lpyj]

Unbelievably good English accent, almost perfect. Not sure how you manage that but well done!

[Dr_LK]

Jenni, I respect and follow your channel since the start, but myth numbers two is not explained correctly. This is an extract from a watchuseek forum, and basically moving your hands cannot change the pressure more than 1%, so it has no effect!

“This mystery lead me to seek out the answer and learn more about water resistance and the effects of dynamic pressure specifically. I did found some important pieces to the puzzle here in this forum from older forum posts but also from Wikipedia and also some Swedish scientists that I had enquired about this mather.

What I did found out shattered the dynamic pressure theory to pieces. It simply was nothing more then a lie turned into an urban legend and myth.

Apparently pressure can only be applied to an object as the result of added mass/weight that is applied to the object(in this case added depth with an increased weight of the water pillar above you) in question, or as a result of expansion or due to electro magnetism, another possible source of pressure is some external forcing preventing expansion or inversion. Another source is gravitational pull due to accceleration or decceleration but that reason is somewhat tied in to reason number one the one about added mass.

So what kind of forces can a swimmer/diver apply to his/hers watch? first we have the depth ofcourse. If we use a watch similar in size to a Raysman. Lets say we are at 100 meter depth. The size of the watch is about 5cmX5cm thats 25cm2 in surface area. 1m is 100 cm so 100m is 10.000cm 10.000X25= 250.000 Cm2 of water above the watch that is pressuring against it. The weight of that water is 1000.000/250.000= 250Kg(550 ibs) of pressure against the watch at that deptht. This is known as the hydrostatic pressure.

The diver(staying at the same depth) can only change that pressure against his watch in 2 ways either by moving his arms up or down but the maximum reach of ones arms is very limited usually not more then perhaps 120cm(4') or so.... that is only a change in pressure of 0.12 bars or 3Kg(6.7ibs) of pressure, very little difference not much more then 1% compared to the rest of the pressure at that given depth.

Second way to increase pressure at the watch is trough speed/acceleration. Either by swimming or by moving our arms up and down. The maximum speed we can move our arms in free air is often not more then 3-6 feet per second and it moves even slower under water. And when it comes to Swim speed even an Olympic swimmer usually cant swim any faster then 6-7 feet per second. If we add the maximum output of that we get up to 10 feet or 3 meters of acceleration per second which is the equvivalant of about 10Km/h or 6.25 mph. That aint very much force/pressure in water. Someone smart here at the forum(CycloneFever) calculated this and I quote:

"Without repeating all the calculations here (they involve denominators and the greek alphabet and are PITA to type out), at a depth of 330ft(100 m) and moving your arm at 3 ft/sec, the dynamic pressure is in the order of magnitude of 0.14 feet of head or 0.04% of the depth. Even assuming you could move your arm at 20 ft/sec (14 mph!) the dynamic pressure is only about 6.2 feet of additional depth (<2%)."

So with this we can conclude that the Dynamic pressure is normaly a small force for a diver and do not limit your watch capacity very much. It only reduces it whit a couple of meters at most.”
