What Makes One Speedmaster Model More Water Resitant than Another?

I just think the way that some members reply to threads is lowly and disrespectful.

I'm sorry but that is simply not true, I haven't been a member here long, 18 months or so, and the people here have helped me immensely.

To get the most out of any forum it pays to spend a bit of time reading before asking, I spent a good few weeks reading the forums that interested me and searching out the topics I wanted to read up on, many don't do that, quite often the question is asked without the poster making any effort to find things out for themselves.

Just wondering what that makes me as I own both a Rolex and an Omega? Oh and for the record, I worked bloody hard to afford my luxury watches, bloody hard.



Actually, I would disagree, I find the OF members to be far more friendly and helpful, the Rolex Forum is quite a cold forum, very little humour, I get a lot more out of the OF forums and threads compared to the TRF, I enjoy and actively comment on both but prefer OF as it has better banter and humour.
You’re entitled to your opinion just like I am.

I own both too and have worked hard as well.

For the record, I wasn’t labeling omega owners vs Rolex owners

It’s just something I’ve heard.

I respect your opinion.

Then why mention it, especially as you own both makes of watch? I don't understand the logic of making the statement when you clearly know that it is untrue.

@schoolboy

You seem to enjoy getting yourself into trouble, don't you. ...

How you manage that, I do not know. ... ((( 😀 )))

What makes One Speedmaster Model More Water Resistant than Another?



Silicone grease perhaps. ... 😀

That might be true, but I think the question the OP meant to ask was 'What makes Omega declare one Speedmaster more water resistant than another?' Al Archer already posted, and I think he said there's no obvious difference in parts (from this 10 atmosphere watch to 5 atmosphere Speedmasters) except for pushers and crown.

My completely uneducated guess: Omega made a mistake, and realized they do not want Speedmaster sales to eat into Seamaster sales. They rather sell you two watches than one.

It would be really cool if that is true!

No, that's not cool. Basing technical watch ratings purely on marketing decisions would not be cool; well, maybe for the marketing guys...
IF IF IF that were true - it's only a guess.

Thank you for the reply, nice to see people finally getting back on topic. (for reference I don't care about rolex forum vs omega forum, I just wanted to talk about WR)

On the one hand I hope it's just marketing because I would then have a more substantially waterproof watch than I hoped for. On the other hand it is frustrating that they would not be truthfull. Do you think the type of gasket could be different? I really couldn't imagine.

This was exactly what I meant, thank you!

If a watch can resist 10 bar overpressure (gauge pressure), it can also resist 5 bar. So labeling it '5 bar' or '50 m' would not be untruthful. It just wouldn't be the whole truth...

I don't know whether Al ever tests 50 m Speedmasters to 100 m; if he does, it would be interesting to know what the results are. Does it essentially always work, does it require resealing often, or does it mostly fail?

Wasn't the compressor case that encountered some leaks at a low-pressure level?

Not sure it was them but I remember some diver watches had issues because they were designed to be sealed by the pressure. The more pressure there was, the tighter the seal. And sometimes, the pressure at shallow depth was not enough to seal them...
Only Naiad crowns and Compressor cases come to my mind with that kind of system.

Production tolerances and surface conditioning are also critical factors.
To put it simply, the exact same seals/gaskets can be used in an assembly that's "made cheaper" and that assembly more than likely will yield less water resistantance across the whole production.

Thank you for that information.
Thats a bit disheartening to think of if that is the case for the standard speedmaster. I know it's not the most expensive watch out there but I would still like to think they did their best, and to think a little better finishing on the case would allow for double the water resitance would be sad.

The finishing on the case is fine, and "more" or "better" finishing isn't going to make into something else. There's no reason to be "disappointed" unless you regularly go down more than 50m, and I can tell you not many people do.

That gets into a whole other mess and the somewhat irrational reason that I'm curious about this in the first place. I always hear conflicting things in regards to water resitance. I hear that 50 meters isnt enough even for wading through a shallow stream, and then from others that 50m is enough to swim with. If it was 10 meters it would put it more in the comfort zone of being able to comfortably tackle basically anything like the occasional swim.

In any case this is all irrational because I never swim with mine anyway. But I have the irrational fear that one day, ill be forced to dive off a waterfall indiana jones style (or something to that end) and my watch wont survive thus leading to NAZI's taking over the world...

Like I said, irrational.

Fifty Fathoms: 91m. By today's standards, you could swim but not dive with it. 70 years ago it was the 1st dive watch and used by people like Jacques-Yves Cousteau. Just saying...

Now, I also doubt he forgot to change regularly the seals.
