Every watch that passes through Gray & Sons goes through intense professional overhauling and detailing. There is nothing left undone. Our Swiss trained watch makers and our watch detailer fully restore all watches to "Like-New" luster and condition. When a watch leaves Gray & Sons (whether the watch is 5, 10, 20 or even 50 years old) it is pristine inside and out. Here is how the process works:

Pre-Owned Watch Restoration Process

Disassembling

Parts replaced from the original factory - Rolex, Omega, Bugari, etc

The mechanism is completely disassembled for inspection and cleaning.

Replacement

Parts replaced from the original factory - Rolex, Omega, Bugari, etc

Individual parts are inspected and worn or broken parts are replaced with new factory original ones.

Preparing for Cleaning

Worn and over used watch parts removed

Once we've chosen the parts that are too worn to use we place the remaining pieces into a wire basket.

Cleaning

Worn and over used watch parts removed

The wire basket is then attached to the cleaning machine and submerged for a 4-step cycle. a. Clean b. Rinse c. Rinse d. Dry

Assembly

Worn and over used watch parts removed

Now with spotless parts the assembling can begin. This takes patience and an incredible attention to detail. It is a job that requires a meticulous craftsman.

Regulated

Worn and over used watch parts removed

With assembling complete we then place the watch in a machine that tests the movement for amplitude, beat and timing. If it is regulated properly we then move on to casing. If not, it will be adjusted as needed until it passes the test.

Case Tightening

Preowned watch case is tighted and sealed

When regulating time is completed we case the movement.

Pressure Checking

Watches are tested and measured for proof of water resistance

The watch will then be tested for water resistance according to exacting factory standards.

Final Control Check

We then place automatic watches on a wheel that mimics the movement of your wrist. This study determines whether or not the auto wind mechanism is functioning properly. Gray and Sons sells beautiful automatic watch winders that do a similar job of keeping your luxury self-winding watch running smoothly.

Pre-Owned Watch Case and Bracelet Restoration and Detailing

Now with the movement out we move on to the other parts of the watch. We make sure everything looks "like-new" by removing any scratches and build up. This is how the process works:

UltraSonic

Cleaning your high end luxury watch

We submerge the watch bracelet and the case in the UltraSonic solution to remove general build up.

Steam Clean

Steam cleaning antique watches

Then we proceed by steam cleaning the watch pieces making sure we remove any buildup left in between the links or hard to clean places.

Drying

Drying designer watch peices

We lay the pieces down to dry before we move on to polishing.

Polishing Wheels

Polishing luxury watches

The case and bracelet are then polished using a series of polishing wheels. First, the back of the bracelet and the clasp are polished with a satin finish. Then, we use the black rouge polishing wheel to remove deep scratches, followed by the red rouge for a final high polish and the last satin finish.
