Your AD is an idiot!
If a watch is water resistant to 100m, then it’s water resistant to 100m... no ifs, ands, or buts about it.
What prevents water getting in are the seals in the crown tube, and as long as they’ve not degraded, then they will keep the pressurised water at bay.
When you’re washing/rinsing the watch, do so with the crown down or steeply angled away from the running water, just to be on the safe side.
Other than that, swim away ‘til your heart’s content.
Here we go again...water resistance
of a watch. I need, yes need, to get a better understanding of water resistance of watches and specifically screw down crown vs non screw down crown and 50 mtr and 100 mtr. I wanted a every day watch that i could take with me in the pool, perhaps a couple...
From my Seiko manual
You do not have to have a screw down crown for swimming in a pool. You do ned a screw down crown for diving though. ...
Thanks for this...
Didn’t occur to me to check the manual and proves my point that my thoughts are correct. However, then why did the AD where i initially wanted to buy the strap said not recommendable for this watch and also that Seiko would no longer uphold the warranty i...

That's what I thought....
considering some of the other replies - will need to take the seals into consideration for sure and having them checked.
Please give me more details from that strap 🙏🏻
It looks amazing on the Seiko and would love to have a blue one on my shippo 🤗
Here's the ISO standard for water resistance
Cazalea Opinion, explained for 5-year old - don't go in the water with a watch on unless it's a dive watch. Seiko Opinion: expressed as a chart SINN opinion: In order to use a watch safely when swimming we recommend a compression resistance of at least 10...
Hear, hear! 10bar is a comfort when dashing to a parking spot in a rainstorm, and that's about it. And a point not yet mentioned...
On the whole, dive watches are much less expensive (the Nautilus, Blancpain 50, etc. obviously excepted) , there are gazillions of styles, and one or two might pleasantly enlarge the aesthetic of your collection. Have you ever really seriously looked into...
Thanks for the alternative...
No, I haven;t looked at one just yet...saw the longines legend (but if i would pursue it it would be the version without date) - I think that I am not yet ready for it, but perhaps in the future.
Like myself! Ha! I don't own one either! And I agree—despite having been tempted by the Seiko—that a date is obviously not necessary for the diver!
It's only there to make the watch more wearable as an everyday piece. Well… good to muse with you!
Sinn should know better: 10 bars does not correspond to a depth of 100 meters ....
... since the air pressure on the sea surface already is 1 bar. So 10 bar corresponds to a depth of 90 meters, not 100. It is typical for so many erranous information given areound water tightness. The pressure resistance rating for a specific case is giv...
Specs can be governed by marketing and legal, rather than engineering
This situation reminds me of a conversation I had with the then-head of service for M-B in the US. As I was assembling the specs for maintenance for M-B passenger cars in our reference charts, I asked why the oil change interval was 20,000 km (~12,000 mi)...
Sinn’s not all that wrong...
... just rounding up to the nearest whole number. Air pressure on the surface has zero effect on water resistance when submerged, since it’s not Hydrostatic pressure. Therefore, at a depth of 100m, the Hdyrostatic pressure is exerting a force of 9.81 bar,...
The irony is...
That the watch I use as my dive computer is a Garmin MK1 Descent which is rated at 100m and my sea dweller is rated 1200m. I'm a recreational diver and I have the basic PADI certification which allows you to go down to ~20m. If/when I want to go see somet...
I don'd dive...
it was more related to sitting and relaxing in the pool and then perhaps a couple of strokes to go from one end to the other (short end not the long one). I understand gaskest/ seals are the most important factor to weigh in, other than the manufacturers ...
