A Rolex dial or paper depth rating only describes the original design target — it does not prove the watch’s current seals or recent pressure testing. Always request a documented pressure/water‑resistance test or have an independent test performed before exposing a pre‑owned watch to water.
A real example from Idaho Pawn & Gold
Close-up photo of a lady’s Rolex-style wristwatch with a diamond-set bezel and dial markers, magnified date window at 3 o’clock, screw-down crown visible at 3 o’clock, and an Oyster-style three-link bracelet. The dial text and crown logo are visible; no handwritten documents or visible serial numbers are present.

Why the rating alone isn’t enough
Manufacturers state a water‑resistance rating based on factory testing of a new, correctly assembled case. Over time gaskets and crown tubes are consumable parts; wear, careless case openings, aftermarket crystals or non‑original crowns can reduce sealing. A printed depth number doesn’t reflect these changes — only a recent, documented pressure or vacuum test reports present tightness. www.rolex.com www.hodinkee.com
What tests actually check the seals
Watchmakers use dry air/ vacuum checks and wet submersion pressure tests to find leaks and confirm acceptance criteria for a specific model. A wet test during service is standard after gasket replacement; a single passing dry test does not guarantee there are no defects that would appear under wet pressure. Insist on recent test results for the specific watch you’re buying. www.rolex.com www.hodinkee.com
Practical questions to ask the seller
Ask whether the watch was pressure‑tested since its last service, whether gaskets were replaced, and if the seller can provide a dated test printout or service receipt. If the watch was opened for polishing or modification, ask who performed the work and whether the case was retested afterward. Without documentation, treat the watch as not water‑safe.
When to seek a professional check
If you plan to wear the watch near water, have an independent, qualified watchmaker perform a full reseal gasket replacement and a wet pressure test or send it to an authorized service center. High‑pressure ratings or aftermarket case changes can require specialist equipment only available at brand service centers or well‑equipped ateliers. www.rolex.com
Red flags and safe handling until tested
Red flags include missing recent service records, aftermarket crowns/crystals, visible case openings or mismatched case parts. Until you have a documented test, avoid immersion and treat the watch for dry wear only; exposure to steam or sudden temperature change can reveal marginal seals and cause fogging or movement damage. www.hodinkee.com
