Your OMEGA guarantee

Your new OMEGA is accompanied by a five-year guarantee, subject to the terms supplied with your timepiece. Keep your guarantee details for future reference. Berry’s can offer personal guidance on caring for your model and help you arrange the appropriate service assessment.

Caring for your OMEGA

Use your OMEGA model’s operating instructions for winding, setting and using its functions. If you are unsure which instructions apply to your movement or reference, our team can help you find the correct guidance.

Straps, bracelets & water resistance

Check the instructions for your particular OMEGA model before exposing it to water. The appropriate care depends on its case, strap or bracelet and the condition of the watch.

For advice on water-resistance testing, bracelet adjustment or a replacement strap, contact Berry’s. Our team can explain the suitable options for your timepiece.

Servicing your OMEGA

If your OMEGA needs attention, Berry’s can help you arrange an assessment and explain the appropriate service route for its model, condition and guarantee status.

Where chargeable work requires an estimate, the relevant details can be provided for approval before the repair proceeds. Ask our team to clarify any separate guarantee offered on the completed work.
