Question about Apple Watch Series 5

In the online Apple Store, the glass for the stainless steel version is also produced in sapphire glass. So only the stainless steel or titanium case makes the difference. Of course, the price is different and I think the titanium version is blacker and shinier. The titanium version is supposed to remain exclusive to the Apple Store. Greetings

Since I work in construction, I think the housing is more scratch resistant, the aluminum version is so quickly full of scratches, so I think of the titanium version lg

Question, why would one want the titanium version? I was in 2 different Apple Stores and asked the staff the same question, why should a customer buy a Watch in titanium or ceramic? In both shops the staff didn't know, they asked among themselves how they should justify it. In the end, the answer was that it looks nicer. That doesn't justify such a surcharge. So here's the question for someone who is interested. Why do you want to buy the Titan version?
