Why do we design the Sapphire Exhibition Case-Back for Rolex ?

This is our true story and design / produce process :

One morning in our office, I opened up the case-back of my Daytona with curiosity, and I carefully watched this Daytona watch movement for a long time, I was very surprised by its precision running and complexity design, and I never knew it was so wonderful.

When I shared this "beating" wonderful mechanical movement with my colleagues, I found that everyone was just staring at this watch movement, they attracted by this charming watch movement, even though they have watched it for a while, but it seems everyone is not willing to leave it.

From this time, I have decided that we have to create a product that makes the Rolex owner able to admire this wonderful watch movement at a glance, and so we set to work on the great item - “Perspective Case-Back”. An extremely high-quality item that is worthy to use with the precious Rolex.

The next day, we had started searching for a way to achieve this goal, we were targeting Switzerland, Germany, and Japan we hoped to find the most appropriate manufacturers to meet our exacting standards, after thorough investigations and many contacts, we finally selected a Japanese professional diver watch-case factory to produce this great item - Perspective Case-Back.

On the first visit to the Japanese factory, this is an extremely clean and well-equipped medium-sized factory, we had a meeting with the Boss, he is a Japanese engineer, and was wearing a full neat factory uniform.

Upon the business meeting with their work team, the boss told us that Generally, his factory does not accept this order, they preferred to produce the Japanese orders, also because our product quality specification requested is too high, but the order quantity is too small.

We were very disappointed to hear that.

However, the Boss told me that he owned a Daytona watch himself also, so he is very interested in this "Perspective Case-Back" project. He agreed to make an exception to take the order with one additional condition, the additional condition is that we have to agree to sell him one set of "Perspective Case-Back" at the regular price once the project is complete.

We have to admire Japanese people's respect for copyright awareness, and we certainly accepted his additional condition immediately.

Honestly, this factory had extremely sophisticated equipment contained in a completely dust-free environment, and we need to wear the non-woven hat and shoe covers they provided to enter their workshop.

Upon I found the trademark "Grand Seiko" marked on a lot of watch-cases in their quality control department, the "Grand Seiko"  is one of my favorite brands.

My heart skipped a beat, and I am so excited because I knew we had found the right factory.

In the choice of product materials; the Boss insisted to use the made in Japan finest scratch-resistant sapphire crystal, FINE.

About the most important material - Stainless Steel, we asked the Boss, where is the best steel material in the world?

We guess the best steel should be produced in Switzerland or Germany, but he said: No, the best stainless-steel material is produced in Japan because the Japanese produce the best steel for knives.

Why ? He said that Switzerland or German knives are very good too, but the Japanese samurai knife is only made from Japanese top-quality stainless steel, please understand that the samurai knife's main function is life-saving or to kill the enemy, you think who will care more seriously about the steel quality? So, Japan had mastered the production technology of top-quality steel a long time ago.

We accepted his professional advice, and then we choose 3 kinds of different stainless steel to produce testing samples, we finally selected one of them that is made in Japan top-quality 316L stainless steel, because of its precision, intensity, density, color, glosses, all are very close to the Rolex 904L steel.

And we particularly made a thin mirror polished ring around the sapphire crystal of Case-Back, which the mirror-polished face width is 0.40mm only.

We named this beautiful mirror-polished ring "Angel Halo".

And we engraved the product content on the case's inside, which the edge wideness is less than 1.0mm only, these outstanding crafts have shown the Japanese factory owned the unique ultra-precision cutting and super mirror surface polishing equipment & technology.

At the most important function - the Deep-sea high-pressure waterproof, we required 100 meters of waterproof for each case-back, after two times of rigorous stress waterproof tests, all of the case-backs passed the 145 meters and 150 meter tests, this test result is much better than we expected.

The boss told me that this is a normal test result in his factory, because all of the watch-cases produced from them, if had marked 100 meters waterproof function, and the reasonable safety factor of waterproof must be 125 meters or above.

I am so proud that we have a dedicated team to work on this Transparent Case-Back, and we are very fortunate to commission this excellent professional factory, combining its outstanding technicians and advanced machinery, and the top-quality Japanese materials to complete this superb item.

We also created the case-back of the Explorer, GMT-Master, Submariner, Sea-Dweller and Datejust with the same attitude, team, and combination.

Now we will continue to develop more models to suit different models of Rolex.
