Water Resistance - any advice
Water Resistance - any advice
I did search but couldn’t find a specific discussion.
I just read an article on Oracle of Time on water resistance. To summarise -
30m don’t get wet
50m caught in the rain ok. Maybe a shower
100m swim in a pool
200m snorkelling
300m proper dive watch
Do we agree with this?
I have a Trident 300 but was actually planning on leaving this at home for summer holidays. I have a Seiko 5 Sports which I specifically bought to take knocks. When we go away in the summer we take our VW California campervan and I spend hours loading and unloading on 5 campsites and with 4 bikes aswell am lucky if I’m not bleeding from cuts. Scratched watch a definite. With the Seiko having 100m resistance, I have bought a fetching CW orange rubber strap and would hope this would work in the pool and crashing in the sea. I have also bought a 100m quartz mint PRX. Perfect for holidays I thought. I also have a 100m Khaki. None of these have screw down crowns.
Should I just risk it with the 100m Seiko? Seems best for beach, pool and camping.
I would rather not take the Trident at all. It will get scratched. I’m aware that sounds really dumb.

5 ATM (50 metres) Water resistant to most household shower units
15 ATM (150 metres) Safe to use while snorkelling in open water
30 ATM (300 metres) Ideal for experienced divers and those practising scuba-diving
60 ATM (600 metres) Professional divers, experiencing prolonged exposure underwater
100 ATM (1000 metres) Professional deep sea diving

Re: Water Resistance - any advice
I’ve got three watches with WR of 150-200 metres (less than the Trident). They all go in the sea and pool.
Err…it’s a swimming watch.

Re: Water Resistance - any advice
I spent decades wearing watches rated at 100m WR in the pool and in the surf. Then I "learned" I shouldn't do that.
Seriously though 100m is fine for most things - although keep in mind that seals can deteriorate with age. If in doubt get a pressure test. These days I tend to go with 150m or higher and AU$500 or lower in price, but that's only as I have the luxury of doing that.

Re: Water Resistance - any advice
Well, it all depend son what you are doing in the sea. Jumping off cliffs? Perhaps not. Going for a swim? No problem.Should I just risk it? I would rather not take the Trident at all let alone take it in the sea
But ... you are on holiday. It's meant to be enjoyable, and if you're worrying about your watch that will impede your enjoyment. So, if you can't "switch off" than don't wear your Trident.
Buy yourself a G-Shock. It will cope with everything you are throwing at it. As will your Trident 300, but you won't stress about the Casio.

Re: Water Resistance - any advice
I tend not to take watches into water, but I have no doubt CW Tridents will be fine. My son has Orient Kamasu watches among
others and takes those swimming without an issue.
Omega say their Speedmaster is safe to 50m depth, and say there is no issue swimming with it - if 50m doesn't mean 50m it's a poor tale really. I suspect it might even fall foul of the Trades Description Act if someone really had an issue.

Which is surely why "waterproof" has been replaced by "water resistant"?I suspect it might even fall foul of the Trades Description Act if someone really had an issue.

Re: Water Resistance - any advice
I would have no hesitation using any 100m watch in the pool and sea unless it was old. The seiko 5 is perfect for what you describe. I have two seiko 5 sports diver style watches that are both 100m with no screw down crown. I would choose those and be unconcerned
Cheers now, Paul
Re: Water Resistance - any advice
Yes @stefs I want to take the Seiko. Thats what I’ll do. That’s what it’s for. I seem to have created some confusion. I know the Trident will cope with water but I want to leave it at home so it won’t get scratched and I don’t need to worry about it.

Re: Water Resistance - any advice
If it were me I would take the Seiko since the other 2 will not wear the scratches as well.
Since you’re not going diving (from what I read) this is a perfect watch.
Me personally I either wear my citizen promaster in the water or my Casio F91W, which has 30m! It’s a case of one is built for the job and the other is disposable. Ultimately I wouldn’t be super upset if either leaked.
If you would be upset if it leaked, don’t take it in the water at all. I had a lovely C65 with 150m and it leaked in the local baths. I was upset. A £167 service addressed the issue.

Re: Water Resistance - any advice
I will take a slightly different approach to this.
First up, I definitely subscribe to the wear your watches ethos. I wore my GMT-Master as a daily for 25 years. That being said, we buy these things in part to make memories with. My advice would be to take the watch you want to make the most memories with. A watch can only truly become special when it is with you during special times in your life.
The 300 can take whatever you can throw at it. Scars become part of the furniture after years of wear. So much to the point that it may become irreplaceable.
Just something to think about.
