How to Repair an Oris Watch

Updated April 17, 2017

Oris watches are a mid-level Swiss timepiece. Watch enthusiasts usually neglected Oris watches due to the low-grade, albeit dependable, movements; but as of 2010, interest steadily inclined over the decade. A movement is the spring-loaded engine that runs the watch. Oris only manufactures mechanical movements, eschewing the industry trend of selling battery-powered quartz watches as well. Repairing the movement is the job for an experienced watchmaker, but the casual watch owner can perform minor repairs.

Use a magnifying glass or jeweller's loupe to examine the crystal---the acrylic, mineral or sapphire glass that covers the watch dial---for scratches. Determine how deep the scratches are by running a fingernail over them. Deep scratches require replacement of the crystal. Surface scratches can be repaired.

Step 2

Apply masking tape to the case of the Oris watch. Cover the case and leave only the crystal exposed. You are protecting the case from unnecessary cleaning compounding getting into case nooks if you are polishing only the crystal.

Dab a small amount of Brasso onto your fingertip and gently rub it in a circular motion on the crystal. In the absence of Brasso, use toothpaste. Toothpaste has similar abrasive qualities. Rub the compound into the crystal for about 10 minutes. Wipe away the excess polish with a cloth.

Use the cloth to polish the crystal once the scratches disappear.

Turn the watch over and inspect with the magnifying glass the case and caseback. Apply Brasso to the case to remove surface scratches. The polishing compound will not work on deep scratches. Repeat Steps 3 and 4 on the case and caseback.

Use a toothpick to remove excess polish from the seam between the Oris case and case back, any case engravings and nooks between the lugs, which hold the band.

Insert a case blade between the lug and band onto the spring bars. Spring bars are fitted through the ends of a watchband or bracelet and inserted in tiny holes in lugs. Lugs are protruding bars at the top and bottom of the case that hold the spring bars in place.

Push the edge of the blade against the shoulder of the spring bar. The spring is contained in a small tube. The tube moves inward releasing the spring bar from the lugs.

Replace the bent or broken spring bar with a new one. Thread it into the end of the band or bracelet.

Hold the spring-loaded shoulder of the spring bar inward with the case blade. Place it over the hole inside the lugs. Release the spring. The band or bracelet is now secure between the lugs on the spring bar.


Most household polishing products with abrasive compounds work well to repair watch scratches.


Never submerge and older Oris watch in water, even if the case reads "waterproof" or "water resistant." Old watches are no longer are impervious to moisture. Never open the case back of a new Oris watch. It takes special tools only a skilled watchmaker can use.
