Water Resistant Seiko Watches
If you buy one of these second-hand do not expect it to be guaranteed water resistant. Often they need new case back seals, winding button seals, and if chronograph , push button seals'. Many retailers will not guarantee the water resistance of a quartz watch during a battery change. If in doubt pay extra to get it ..re-sealed , particularly if its' an expensive watch like a Rolex, or Omega etc.
