Would anyone dive or has anyone dived with this watch? I really dig the look but don't have a high opinion of watches with just 100m resistance for doing the 40ft dives I like in the ocean or in lakes.

m0arpheusIn this case, you'd be much better off with a Seiko diver like an SKX, a Sumo or a Samurai. You'll get 20 ATM and a diver unidirectional rotating bezel.
If you don't like the diver style, Seiko has plenty of automatic watches with 20 ATM resistance, in example even my SARB017 has 20 ATM, even though its dial, hands, small lume, small size, absence of diver rotating bezel make it useless for diving.

m0arpheusThis watch isn't suited for dives that deep. It might say 100m but it's only meant to be worn when swimming at the beach or in a pool. Listen to aleskb and get a proper dive watch that is rated at 20atm.
It's really annoying that they say it can reach depths of 100m or 200m when in reality aren't meant to.

Blair_BlackThey do, I lhave went 30-50m down with watches rated to 30m. Most legitimate brands actually live up to there word on those. maybe not an Invicta, but I would trust a seiko to 40m.

Blair_BlackI scuba dove with plenty of 30-100m rated beaters when on holidays. Yeah, with a 30m you are pushing your luck and there is a small chance it won't make it, but I would expect a 100m watch to easily survive recreational diving. I spent half a year in Thailand teaching scuba with a 100m rated watch; admittedly it was a purpose built dive watch, so probably was pretty conservatively rated - but still... Remember, most dives don't go past 15m: you want to keep your nitrogen load down and your air time up.

huyghe27Yes but this watch isn't meant to be a dive watch. The watch may be rated at 100m but that doesn't mean they actually stuck it on a person an dove with it. They do these test by exposing the watch to the pressure of 100m depth of water. The watch isn't build for diving so it probably won't hold for regular and prolonged diving.

consolationThat may be but this watch isn't build for the purpose of diving and the chance that it was tested during actual diving is very slim. It probably won't hold if used for prolonged and regular diving even if it isn't at 100m. Maybe it will. I personally wouldn't count on it.

Blair_BlackThey test beyond 100M, like I said, maybe not an Invicta, but an Orient or Seiko, YES. Google how many complaints seiko has about water intrusion, not counting someone forgetting to screw down the crown of there skx007.

huyghe27Testing is done in a quiet water tank with pressure being gradually increased to 100m. No water rushing around the watch like there would be when scuba diving. This watch is designed for swimming, some light snorkeling, and a shower. 30m-50m is designed for wearing in the rain, and not a monsoon either. For diving, 200m is where it's at.

huyghe27There is a vast difference between being able to reach depths of 100m and being built for it. As ghostwriter said the use a pressure tank for the testing. That means that the watch first of all doesn't get exposed to current. The watch doesn't get exposed to saltwater either or the temperatures of the sea. A dedicated diver watch is made to resist these things. So like I said I personally wouldn't count on it holding up to diving regularly or prolonged.

huyghe27Lol. If you forget to screw the crown of any watch including a Rolex submariner, it will take water just by going in the shower. Obviously, water resistance comes at the condition that the crown is screwed down...

Blair_BlackI think people really overestimate how much water movement a watch encounters when scuba diving - if you're flapping your arms around, you are doing it seriously wrong; most movements are slow and smooth with arms tucked close to your torso. Yes, movement will increase pressure acting on the watch, but we are not doubling it imho. I'm just going by 15+ years of teaching scuba diving; the only time I've seen a 30m+ watch fail is when it was smashed against rocks by surge, due to a miss-timed exit.
Having said that; I personally use a 300m rated olympics, they are robust as hell but cheap enough that I won't cry when it inevitably gets a tank dropped on it... but, I dive, a LOT. If you do the odd pleasure dive on holidays, the odds of your 50m watch failing are miniscule. IMHO, manufacturers are inflating the recommended depth ratings to get people to buy a "special" watch for those once a year dive occasions that most rec divers experience.
Now, if doing some edge of an envelope, tri-mix, dive; yeah I would get a 400m+ rated bomb proof watch - even if it happens once a year - but, this is not what we are talking about.
TL;DR - 15 years of teaching scuba, never saw a 30m+ watch fail on rec. dive. Not something to worry about unless you dive all the time.
PS. I'm going to give an unsolicited plug to http://www.olympicwatch.com/popuppages/28534.html -never paid more than 200$ for one, but, they are amazing work horses that are near bomb proof - however, when you finally drop it off the side of the boat; it's not some finely crafted automatic that you will miss. Industrial strength tool, is all - but has a simple charm because of it. My watch will die every year or two - never while on a dive, but it will get a tank dropped on it, or go flying overboard, or will get loaned to a client that will "forget" to return it etc etc - if you just got certified, and are looking for a never fail watch, that you won't get sad over destroying - you won't find better. Having said that, my partner's has been going for years without an issue, so longevity is not a problem (and they are easy to service if you are in the wops.)
