• When you get a watch serviced is the WR value maintained?

    A full service should include seals (caseback and crown) and a pressure test, which is quite complex but can be carried out to any water resistance value. A movement service doesn't need to be included with a pressure test but this is usually done at the same time. Ask your watchmaker whether he can do a pressure test. Typically a pressure test will cost in the region of £50-£75 I believe, with a full movement service (not just adding some oil but fully disassembling, cleaning and reassembling the movement) should cost no less than £300, depending on the movement and whether parts need replacing.

  • For simple movements that just require a clean and lube, Alsal can charge less than £100 for a service. Obvs depends on what you've put in front of them though.

  • that is cheap! Presumably doesn't include movement disassembly though, right? Is it Just a few additional drops of oil in the right places and fish out any lint? :)

    I struggle to see what they could clean in any meaningful way without disassembling the movement.
