Water Resistance on Apple Watch Series 7

Hi,

I bought my apple watch about a year ago, it is a 7th generation watch, and just yesterday I accidentally put it in the washing machine for a cycle. This cycle contained detergent in powdered form and a fabric softner in liquid form.

By some divine miracle, my apple watch still works (thank god), but I am worried about its water resistance coat for future activities, as this, no doubt, has surely worn off some of the water resistance coat.

I am wondering, is there any way I could get a new water resistance coat applied whether it be from apple themselves or a reliable third party which would be compatible (and safe) to apply to my apple watch?

Thanks
