AP Royal oak no screw down crown and water resistance

[midwesterner]

Good morning everyone,
My AP 15550st doesn’t have a screw down crown but it provides 50m of water resistance. Apparently this is fine for everyday wear but I like to wash my watches with dawn and water from the faucet (every few weeks).

Thoughts?

Good question!

I have a watch that’s rated to 3 bar water resistance (30m) and that has a push down crown and I keep it well away from water.

All other watches I’ve had/have atleast 100m resistance and these all get frequently washed (twice a week I’d guess?) under warm soapy water with a dedicated toothbrush.

I would probably treat a 15550 the same as I treat my 3 bar watch although I’d for sure dunk the bracelet under and give it a good scrub.

Keen to see the thoughts of others as I do really fancy a 15550 at some stage hopefully in the not too distant future.

I do this with my 16202, which doesn't have a screw down crown. I also swim with it and will swim to the bottom of the pool (usually 1.5-2m)

Same here with my 16202. Wash regularly with soap and water and a brush and goes in the water no problem. 50m is good for most activities other than diving I’d guess.

50m WR is 50m deep.

I think washing it might just be ok?

From AP site FAQs,



Therefore 50m means 50m to me from that.
