Each Rolex watch lovers are obsessed with the exquisite craftsmanship of Rolex, but how many owners have personally saw the Rolex watch movement?
Do you know it is how beautiful & charming? Each one is the watch craft industry's top masterpiece, from the escapement system, balance-spring, colored gears, and the stable rotor they are showing the excellence and aesthetics of Rolex.

In morning of office, I opened my Daytona's case-back with curiosity,
I was surprised by the Daytona watch movement's precision design and complexity, and I never knew it was so beautiful.
The constant praise came from mouths of many colleagues, each person stopped working and only Intently staring at this beautiful watch movement's operation, and everyone took out the phone for shooting, my colleagues are attracted by this charming watch movement, even they do not willing to leave. From that moment, I decided we must do everything possible to create a super high-quality “Sapphire Perspective Case-Back”, so that this beautiful watch movement can showing in front of us at any time.

From the next day, we are starting information search for this goal very hard,
we are target to Switzerland, Germany and Japan which hope to find the most appropriate watch manufacturers, after repeated in-depth understand and contacted, we finally selected a Japanese watch-case manufacturer to produce this great item – “Sapphire Perspective Case-Back”.

We are the first time to visit this Japanese factory, it is a very clean and well-equipped medium-sized factory, their Boss wearing full set factory uniform, and also he is a Japanese senior engineer.
He told us frankly that their factory generally does not accept foreign order, they always producing only Japanese brand watch cases and parts, also our purchase order are too small, and the quality requirement is too high.

At that time, we were very disappointed, the Boss said: but this is an exception case, because he has Daytona watch too, so he is extremely interested in this “Sapphire Perspective Case-Back” project, and he has an additional term, that is we need to sell him one piece at our regular sales price when the project is completed.
We are very awe for the lofty copyright awareness of Japanese, and we certainly agreed immediately.

And then he took us to visit the factory's dust-free workshop, and we need to carry their non-woven hat and wearing the shoe covers to enter, and we saw many of sophisticated machineries and equipment, in the quality control room I saw their QC staffs are inspecting many of bottom perspective style watch cases, when I watch these product trademarks are the "GS". My heart was paused a moment, and I laughed secretly, because I know we have found the right factory.

In the choice of product materials; the boss insisted to use the made in Japan finest scratch-resistant sapphire crystal, regarding the most important steel material; the boss asked us where are the best steel material in the world?
We said the Switzerland maybe Germany, he said: the steel material that makes knife is the best.

Switzerland or Germany knives are good also, but our Japanese samurai knife always made by Japanese top-quality steel material only, please understand its main function is for life saving, you think who will more serious to make quality steel?

We accepted his professional advice since it really makes sense, and we deliberately used four kinds of different steels to produce testing samples, finally we selected the made in Japan top quality 316L stainless steel, because no matter its precision, intensity, density, color, gloss and texture are very closed to Rolex 904L steel.

And the boss suggested to particularly make a super thin mirror polished ring on each product of sapphire crystal periphery circumference, which that mirror face width is 0.40mm only.
We named it "Angel Halo".
And we carved the product content on the bottom shell which the edge width is less than 1.0mm only, these outstanding crafts to show that they owned the unique ultra-precision cutting and super mirror surface polishing equipment & technology.

In the high-pressure waterproof, we required 100 Meters waterproof for each product, after two times of rigorous stress waterproof test, all products are passed the 125 meters and 150 meters tests, this test result is much better than our expected.
But the boss told me this is a very normal result only, because the Japanese watches which marked 100 meters waterproof function, its reasonable safety factor must be 125 meters or more.

Honestly, I am proud of this excellent factory, team and boss, and we are fortunately, each product is crafted by wearing neat, polite, carefully & excellence technician, I can say each product combined with the Japanese superior culture, cleverly technology, and Japanese top aesthetics, can be described as a glamorous handicraft.
