Black Bay Maintenance Question

[HERITAGE82]

I have a Black Bay and I use it on the supplied fabric strap. I have a few questions for fellow owners regarding the maintenance:

In the manual it states that the Fabric strap is not to be used I the water. It uses the same wording as it does for the Leather strap (very strange I know, but check your manuals yourself).

I do not understand how this could be since it is a dive watch and the advertising has it wet with the fabric strap on it. I had an AD call Tudor USA and they said “well follow the manual.”

So what would the reason be for the strap not being used in the water? Also, to those that have used it in the water are there any strange repercussions, such as smell or deterioration.

Also, since the spring bars are sewn into place on this strap do we need to remove the strap after each salt/chlorine water use to clean the case back with fresh water? This seems a bit tedious, but if the case back and strap are not washed with fresh water properly then it could cause rust on the case back due to constant contact with the fabric strap that has salt/chlorine residue remaining.

I am not overly concerned with this and could remove the strap after exposure without a problem since I have done it so many times, but it just seems like a non-WIS who would purchase this watch would not be inclined to do so for cleaning.

Thanks for your input!
