To preserve a Seamaster’s water resistance, keep its crown secured as directed by the manual for your exact reference, rinse it with fresh water after sea swimming, avoid chemical exposure and impacts, and have its water resistance checked annually by an OMEGA-authorized service centre. A depth rating describes a specification—not the present condition of an individual watch. Seals age, and damage can compromise them.
What a Seamaster’s water-resistance rating does—and does not—tell you
A stated water-resistance rating is not a permanent guarantee that a particular watch remains sealed. OMEGA says gasket ageing and accidental shocks can affect water resistance, so the watch’s current condition matters as much as its original specification. An older watch, or one that has taken a significant impact, should not be assumed safe for swimming or diving based only on its name or rating.

Before swimming or diving
Check the crown and controls
Follow the manual for your specific model. If it has a screw-down crown, return it to its wearing position and screw it back in as instructed after setting or winding. OMEGA’s manual for Seamaster reference 217.32.42.21.01.001 says, “The crown should never be manipulated in water.” Do not assume another model has identical crown or pusher instructions.

Chronograph pushers require particular care: permission to operate them underwater is not universal. Verify the exact model manual before pressing any pusher in water.
Do not rely on the rating alone
OMEGA recommends an annual water-resistance check at an authorized service centre because sealing components can age or be affected by impacts. Until a watch with uncertain condition has been checked, avoid exposing it to water.

After salt water and routine cleaning
Rinse after sea swimming
After swimming in the sea, rinse the watch with fresh water. This removes salt from the exterior. It does not test or restore the seals.
Clean suitable materials gently
OMEGA’s care guidance says metal bracelets and water-resistant cases can be cleaned with soapy water and a toothbrush, then dried with a soft cloth. This instruction is material-specific; do not apply it to a leather strap. A toothbrush is a cleaning aid, not a tool for testing water resistance.

Protect the case, bracelet and seals from damage
- Avoid direct contact with solvents, detergents, perfumes and cosmetics; OMEGA warns these can damage the case, bracelet or gaskets.
- Avoid mechanical and thermal shocks. If the watch takes a significant impact, arrange a professional check before wearing it in water.
- If you notice condensation or suspect moisture has entered the watch, stop exposing it to water and have it assessed by an authorized service provider.
How often to arrange checks and maintenance
Water-resistance check: annually
OMEGA recommends having water resistance checked once a year by an OMEGA-authorized service centre. This is a manufacturer recommendation, not a guarantee that a watch will pass or remain safe between checks. The result for an individual watch depends on its condition and must be established by professional assessment.
General maintenance: typically every 5–8 years
OMEGA’s general care guidance recommends maintenance every 5–8 years, with the interval depending on the model and how it is used. That broader maintenance interval does not replace the annual water-resistance check, and it should not be treated as a promise that every Seamaster can wait until the end of the range.

For testing or maintenance, use an OMEGA boutique or authorized service centre. No specific service price or appointment availability can be established without the watch’s reference, condition and location.

When not to wear the watch in water
- The crown or controls are not secured as directed by the model manual.
- The watch’s water resistance is overdue for checking, particularly if its age or service history is unknown.
- The watch has suffered a significant impact since its last professional check.
- There is condensation or another sign of possible moisture ingress.
In these situations, avoid further water exposure until an authorized service provider has assessed the watch. The correct pressure-test result and required repairs cannot be determined from the model name alone.
