·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

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.
Oh crap, I prematurely snorkeled again
I have 2x 9300 (one steel and one ceramic) - both display back. One is 50m and one 100m...





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 😕

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.
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.

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?
