More on Bulgari Case-making: Polishing & Assembly

After case pieces have been designed, milled and stamped, they move on to turning and polishing to get closer to that finished refined look. All the polishing is done by hand.


Polished cases


A small assortment of cases in different stages of finishing

Final Assembly

The polished cases then move on to final assembly and quality control. In this step the crystal gasket is put in place and the glass is installed. 


The glass is pressed in with a small press, securing the crystal in place.



More complicated cases consist of many parts that need to be assembled.


When the assembly of the cases has been completed, they are then tested for water resistance. The standard tests are for 30 meters, the tester in front, and 300 meters, the smaller tester in back.  Actually the cases are tested to 40 and 400 meters and for periods of time of up to 3 hours. 


The cases that pass the test for water resistance are then inspected again and are packed in soft resilient plastic to protect them. 




Do you prefer polished, brushed or another type of finishing?

The next stop is Neuchâtel where we will see how the bracelets are made. To be continued...

Ping, Thank you for this wonderful photo report. I'm amazed to learn that Bulgari do all case finishing by hand and this, by my book, is a very important fact because requires very skilled and true artisans. After all, this is the main reason why we wear mechanical watches, IMHO. Cheers, Nilo

I always prefer a case that has both polished & brushed finishing when it comes to sports watches such as the Bulgari Diagono X-Pro. This combination gives me a better visual impression of the case. For dress watches which are slim, my preference is polished finish. Cheers, Anthony

The pictures and the process really help us understand how much manual work goes into the assembly of fine watches. It is always a pleasure to get a behind the curtain look at what goes on at the manufacture. Looking forward to more. Bill

. . . polished, or a combination works for me, but given the warm luster of gold, a purely polished finish can come across as overly obvious. Restoring brushed finishes to cases and bracelets is a complex task; not every watchmaker has the artistic sensibility, or proper equipment, to perform the task. Thanks for sharing this report showing how it's done at Bulgari. Best, Art

I have not visited Bulgari manufacture but have been to a few other brands...... I think there is no one preference of finishing because the best and most difficult is a case with many different finished surfaces. It looks like Bulgari has the added experience with the jewelry business to also produce good watch case and bracelets.
