Some soap molecules are smaller than water molecules ...

It鈥檚 always a little risky to swim with a watch with low WR even if pressure tested. Worst condition is jumping in to cold water a hot day. Rapid cooling down of the watch cause under pressure that may suck in moisture in the watch even if seals are okay.

I believe Rolex made a Dishmaster

About all the water those watches will ever see.

Before it ends

There is often misinformation on these threads. And quite frankly some crazy points of view to suggest the speedy is incapable of withstanding anything more than a rain shower.

Water resistance comes from the use of gaskets and sealants. The speedmaster has the same seals as the seamaster.

The speedmaster is likely able to dive deeper than its expected depth of 50m

The seamaster is rated deeper because like most designated dive watches it uses thicker, bigger and stronger cases to withstand significant changes in pressure and temperature. Along with deeper rehaut and crystals.

Screw down crowns have virtually nothing to do with water resistance. They primarily protect the stem from damage and accidental use.

It is a fact that the screw down crown can prevent dust or particles reaching the seal which in time can act like grit and reduce the seals effectiveness.

And that there is the key, correct maintenance and you won鈥檛 have any issues. Just with a speedy, you won鈥檛 have the protection around the pushers and with them being manual wound watches any debris in the seal when winding can weaken the seal quicker than other screw down automatic watches.

There sure is, quite a bit of it is in your post above. Could you point me in the direction of any post claiming that a Speedmaster is incapable of withstanding anything more than a rain shower?
