I think that would apply to professional divers rather than swimming pools.
Another one of those 1st world problems. I took my 16710 GMTII away on holiday with me but when it came to the pool I switched to a G shock. Official advice is pressure testing every 12 months despite service intervals of +5 years. Does anyone recommend the best route for getting my watches regularly tested (50m is fine) without going to the cobblers or unnecessary servicing?

No idea how good this is, but it looks interesting.
From TZ no less
Swimming pool will be fine unless just wear the watch
