[One of the many] reasons Rolex is so successful

Ever heard of Rolex?  If the answer is no, you have probably been hiding under a rock.  I have heard that Rolex has twenty-five percent of the luxury watch market, which is staggering if you think about the number of luxury watch brands that exist today.  

Rolex is synonymous with many things, including quality and excellent timekeeping.  If you pay attention to mechanical watch media, you will also gain a deeper understanding of the machine (pun intended) that is Rolex, as a company.  Rolex does nearly everything in-house, including creating its own proprietary metals - yes, melting elements into cases and bracelets.  (Source https://www.hodinkee.com/articles/inside-rolex).

Another thing Rolex, as a timeless brand, does is create timeless models, like the Submariner.  Wait, other brands create timeless models too, like the Nautilus, right?  Yes, but, where Rolex differs is that they do not vary, fundamentally, in the complications offered in each of their models, other than date or no-date on a couple models.  Does Patek Philippe offer a Nautilus Chronograph?  Yes.  Does Blancpain offer a Fifty-Fathoms Chronograph?  Yes.  Does Vacheron offer an Overseas model with a simple date or a Chronograph?  Yes, and yes.  Does Rolex offer a Submariner Chronograph?  No.  Actually, the answer is absolutely no.  The chronograph offered by Rolex is the Daytona.  THE DAYTONA, which is arguably the most coveted watch in collecting at the moment.

Rolex offers many of its watches in different metals, but fundamentally they stick to one thing and do it incredibly well, which has led to them being the powerhouse they are.  One last parting opinion, if Rolex had issued a "Submariner Chronograph" instead of the Daytona, I wouldn't be writing this article (that nobody is going to read anyway), because Rolex would be just like every other watch company, releasing version after version trying to increase sales in the short run but harming the brand over the long-term.
