This popular and highly desirable chronograph watch is made of stainless steel and yellow gold with an Oyster band. It comes with a 40mm case, white dial with gold markers and bezel, and a sapphire crystal. The Rolex Daytona was introduced in 1963 to accommodate the high demand for professional racing drivers and almost 60 years after its launch, it is still as modern and iconic as in its first-day view, an attractive watch no doubt.
This specific watch is powered by a Zenith El Primero, caliber 4030 automatic self-winding movement.

 

It is always a great privilege to work on such a beautiful and sought-after watch.

 


Gray and Sons received the watch from a collector that wanted to make sure we were going to follow manufacturers’ protocols to keep this watch 100% original and protect its present and future value.

Our Swiss-Trained watchmakers took the job with great passion, as usual, as we love the intricate movements of a chronograph and appreciate the watch enthusiasts that wear them.

A watch like this is a source of infinite pleasure and is always a conversation piece as it does not go unnoticed; it is highly recognizable and appreciated.

At Gray & Sons, we make it personal to bring every timepiece back to its original splendor.

So the process begins, the movement is removed. Case, bracelet, and buckle are sent to one of our highly specialized watch polishers to detail and buff up the stainless steel and gold to its original beauty, which requires a very clear understanding of the job to be done with each timepiece, to make sure that each part of the watch continues to be as original as designed: in this case, satin and shiny stainless steel and shiny yellow gold.

 

 


Meanwhile, our watchmaker had disassembled the movement to the barest parts. Cleaning the parts using a multi-stage process to remove dirt and old dried lubricants to bring this great movement back to its best performance.
This process takes approximately 9 to 10 working days to be achieved as no shortcuts are used, we, at Gray & Sons, only do this the old fashioned way of the antique watchmakers. The movement is put together again to start working on the regulation, timekeeping accuracy, power reserve, chronograph functions, and synchronization of all the parts involved for this magnificent movement to keep time, this new process taking 10 days.

Then the watch will be re-cased, and for the final checks, two specialists will test the power reserve of the movement manually, then check the power reserve using mechanical wheels for timekeeping and winding, finally pressure testing machines to check for leaks on the seals and gaskets, this will take another 10 days. The watch is almost ready to be shipped back and as a final stage, we will have another associate check everything all over again with new eyes and have these final tests done again before we ship it back to the owner.
