By replacing the seals and pressure control in a closet, your watch is guaranteed waterproof to release as described in your warranty card.
Watch manufacturers recommend you get the seals replaced with every battery replacement and pressure tested at a service center to guarantee the water-resistance. In practise, the survivability of the watch will depend not only on the water deph, but also on the age of the sealing material, chemicals, chlorine and soap age sealings rapidly. Don't operate the crown or push buttons while under water, close the crown at all time.
