Almost every watch manufacturer recommends that you check the waterproofing of your (dive) watch at least once a year due to the degradation of the rubber seals.
I presume this would be more of a problem in the tropics than in colder climes.
My concern is that every once in a while I like to give my watches a gentle cleanup with an old toothbrush under a running tap. Basic precautions like screwing down the crown are a given.
So, does anybody on the forum actually get their watches checked for waterproof ness? Especially the diving crowd? Would a dip in the pool be a cause for concern if I wear my 4yr old Seiko monster?
Thanks for ur time.
