Hi - anyone know why my speedy 9300 in steel is rated 100m WR yet the DSOM is only rated at 50m ? Not that I’m going diving ! Just interested
Cheers

 

Press on back vs screw back I would assume.

 

SNORKEL!!


Oh crap, I prematurely snorkeled again.

And agree with @Evitzee

 

omg, the way the B U L O V A letters are connected is triggering my OCD

 

Some of the OMEGA applied lettering drives me nuts- particularly the ones that are ever so slightly crooked. I got rid of a watch because of that...I’ve actually gotten rid of others for lesser offenses.

 

I had an IWC portugieser in the past that was delivered and had such poorly aligned indexes on the railroad track that I just sent it right back and haven't considered the entire brand since. Seems pretty crazy to me that in today's manufacturing where the dials are clearly being machine applied that they can't get tolerances to the point where it doesn't look like a wonky mess.

 

Satanic watch :=)

 

No, don’t fret: word on the street is that your premature snorkeling is an exceedingly rare occurrence...

 

I have 2x 9300 (one steel and one ceramic) - both display back. One is 50m and one 100m... had not noticed the difference before. It does look like the back closure is the reason as per @Evitzee comment. The reinvented Naiad lock (deep black etc) seems to have fixed that. I will stick to a 2254 when taking a dip (still shows that watch is good value at 30 bar)...

 

Luckily most recreational divers don’t dive deeper than 25m ... and so both are dive-able as 50m is good for 50m ... or is it

 

It is a good point … I am a desk diver but when entering the pool I prefer P for plenty (Victorian engineering) so raise the performance bar to cope with any floundering and performance pressure :0)

 

As confirmed by many, including the resident watchmaker @Archer, 50m means 50m. The risk is (1) Seals are compromised , (2) The pushers are accidentally depressed while submerged.

(1) Applies to all watches regardless of WR rating.
(2) Doesn't mean that water will be guaranteed to rush in if they are. I've accidentally pressed the crown and pushers on my X-33 G2 when swimming multiple times and it hasn't leaked (had it for 15 years). Now, I wouldn't go around doing it on purpose but just wanted to point out it's a risk and not guaranteed to be happen or be an issue.

 

Get one of these and you can depress the pushers with impunity:

 

Here is the official word from Omega:



Source, the FAQ on their website): https://www.omegawatches.com/fileadmin/Customer_Service/omega_water_resistance_chart.pdf

 

It varies depending on the manufacturer. Check the manufacturers guide. Omegas ratings are clear 50m means 50m but for example Langes guide is as follows:



So even if they claim 12 bar resistance (120m) no deepdiving and 3 bar( 30m) means only splash resistance.

 

Yes, I have seen this too

 

Nice to see a "modern" chart that reflects reality. Citizen still only advise up to snorkelling for a 200m WR rated watch. Errr....sure.

 

I wonder if that's a throw back to the old charts where you "need" 300m+ to go diving in? My guess is the 3bar warning is due to not having screw down crowns or pushers. Any vigorous underwater activity has some risk if they aren't secured. I get why the manufacturers issue that warning though, it protects them from customers doing silly things and then expecting it to be covered under warranty.

 

Interesting.
That's not what the Omega chart used to say.
I wonder when it changed?

For example, the Omega chart used to say that 50m water resistance was only suitable for swimming and this is in accordance with the industry standards of old where the usage was guided by the water resistance.
I can still picture the person swimming on the surface of the water.
Perhaps Omega is trying to up their game.
But let's face it. Who in their right mind would go scuba diving wearing a Speedy Pro, down to a depth of 50m and expect it to come back to the surface ok?

 

Bottom right of the PDF says July 2013.... But I too remember a webpage with icons and an explanation saying "Shower, Swimming" etc, and it wasn't that long ago that I saw it. That PDF is linked out of their FAQ.

Speedy Pro at 50m... well, maybe it's like the guy who once test-drove my brothers MX-5 when he was selling it, instead of slowing down for a violent speed hump, he drove over it going above the posted speed limit. When my brother asked WTF was he doing, his response was "the car should be able to do that".

Of course it can, but it doesn't mean you should do it... (especially in someone else's car).
