It depends on the exact Nautilus reference and the condition of the individual watch. Patek Philippe lists the current ref. 5811/1G-001 as water-resistant to 30 m, while official specifications for some other Nautilus references state 60 m or 120 m. Those figures are not a collection-wide swimming guarantee, nor do they establish that a particular watch remains sealed.
Why there is no single Nautilus swimming answer
Nautilus water resistance varies by reference and generation. A rating published for one model should not be applied to another, and a model’s specification cannot confirm the present sealing condition of a used or aged watch. The figures below are Patek Philippe specifications, not independent test results or guarantees about an individual watch today.

What Patek Philippe says about the current 5811
Patek Philippe’s product listing for the white-gold, 41 mm ref. 5811/1G-001 says: “Water-resistant to 30m.” It also specifies a screw-down crown. The listed 30 m rating is the model’s published specification; the listing does not itself say that the watch is suitable for swimming. It is therefore not sound to turn that number into an unconditional swimming endorsement.

Identify the exact reference
Check the reference rather than relying on the Nautilus name. The examples above range from 30 m to 120 m in Patek Philippe material, so advice for one reference may not apply to yours. Also check the manufacturer’s instructions for that exact reference.

Consider the watch’s condition
A published model rating does not tell you whether an individual watch is currently water-resistant. The specifications cited here do not establish the sealing condition of a particular watch, especially one with an uncertain service history or condition. If you cannot establish that condition, seek qualified Patek Philippe service or inspection guidance before exposing it to water.
Interpret higher-rated references narrowly
Patek Philippe published 120 m for the ref. 5711/1A-014 in 2021 and for the ref. 5980/1 in its 2006 technical release. It published 60 m for the ref. 5712/1 in 2006 and the ref. 5740/1G-001 in 2018. These higher figures distinguish those models from the current 5811’s 30 m listing, but they do not establish that every individual example is safe to swim with regardless of age, service history, or condition.
