Corum Bubble Limited Edition Jolly Joker
Gray & Sons Jewelers, located in Miami Beach, Florida is an independent watch service center, repairing Corum Bubble Limited Edition Jolly Joker watches since 1980.
Joining Corum’s collection of Bubble Edition models, the Jolly Joker Corum Bubble watch was released for a Limited run in 2002. This special edition Joker Bubble watch was limited to 777 pieces.
With the watch, those who purchase the Corum Bubble also receive a box containing a deck of joker themes playing cards and a scroll depicting Joker’s role throughout history. Additionally, one should receive the warranty cards in a wallet with a wiping cloth.

On the watch itself, the dial is divided into black & white quadrants to depict the Joker motif. At six o’clock there's a date window stacked under the hour chronograph register. At 3 ‘clock the dial displays the sub-second register and the 9 o’clock carries the chronograph minute register.
The design of the Corum Bubble Joker watch is sure to get any watch enthusiast excited, especially those with a love for card games and all the Joker’s abilities.

Gray & Sons - Top Watch Repair Service Center For High Caliber Watches
This watch came to Gray and Sons through a seller looking to sell their Corum Bubble Joker. Although the watch looked fine on the outside, factories recommend one to service automatic watches every 3-5 years to upkeep the quality of the watch’s timekeeping. This watch also was not passing our water resistance test using the Witschi Machine.
We must ensure all boxes have been checked when quality controlling an item that will eventually acquire a new home. Every watch that comes into Gray and Sons Jewelers for repair will automatically receive a 12-month warranty once received by the customer post-repair. Gray & Sons check the automatic rotor to make sure the watch’s power reserve is functioning properly, timekeeping accuracy, water resistance, chronograph accuracy, and several other quality control tests.

First things first, we open the case back of the watch and look for any rusted or damaged parts that need sourcing. In this case, the movement was in good condition, the movement just needed some maintenance. Once we’ve diagnosed the problem on the watch and know what extra watch parts are needed, our watchmaker takes apart the watch piece by piece and prepares it for overhauling.
The watch movement, crystal , and watch stem are separated from the head and bracelet . The case and bracelet are given to our head polisher while our watchmakers begin working on the movement. Piece by piece, our watchmaker begins dismantling the watch’s mechanism and evaluating every piece.
Once the watch parts that need sourcing are identified, our watchmaker prepares the timepiece’s screws, springs, pivots, and plates to be cleaned and sources the parts that are needed. We use six different cleaning solutions in an ultrasonic machine to make sure all dirt, dust, and dried oils are extracted from every crevice within the watch parts.
Once the watch parts are cleaned, the watchmaker starts to reassemble the movement while adding lubricants wherever designated and replacing all the gaskets for water resistance.
This tedious process usually takes anywhere from two to five hours per watch! Of course, assuming the watchmaker isn’t interrupted and all parts continue functioning.
While Gray and Sons’ watchmaker worked on the movement, we had our polisher give this watch a light polish around the case to remove the minor scratches. He then put the case in our ultrasonic machine for a bath and finally to rinse and dry.
Once our watchmaker puts together the movement and re-cases the watch, it's time for the final steps of our repair process. Prior to returning the client their watch, we must execute a final quality control process to ensure the watch is running as accurately as possible.
In this quality control, we measure the watch’s amplitude using special machines that listen to the heartbeat of the watch. We also test the watch’s water resistance with a machine that simulates a deep plunge using air pressure to check for leaks.
Additionally, we check that all complications are functioning fully; in this case the hour and minute hands. If both timekeeping and water tests pass, the watch gets put on our winding wheel for observation where it rotates and mimics the movement of the wrist for 6-8 hours.
The watch must then rest and run for the next 20-30 hours.
With this machine, we can analyze the durability of the watch and make sure the movement is functioning and not startled by any natural jagged movements of the wrist. Our complete restoration process can take up to 8 weeks.
