Mechanical watches aren't necessary. They're a giant money pit compared to a quartz, and keep worse time. If you don't have a hard on for intricate, complex, machinery and just want a nice looking watch, quartz is more than appropriate.
The only maintenance a quartz needs is a battery every few years. Runs ya $5. A mechanical watch? Servicing is recommended every few years, and runs anywhere from $100 to $10,000 for the really nice and delicate stuff.
There are affordable, durable (meaning less servicing) mechanicals like the Sekio 5, and one of those would be a nice choice. Or a vintage russian watch (mostly hand wind, but some very cool designs, and famously durable motions- search for Vostok or Pobeda). Or, you could buy a quartz that would be indistinguishable from an automatic to anyone but a watch dork upon close inspection. Which will last you half as long for a fortieth the price.
High end mechanicals are luxury items, and unlike something like shoes or suits, the increased complexity of the construction leads to no practical benefit. A nicely designed quartz would be an excellent choice. I wouldn't trust one from a brand not know primarily for watches, since they're probably overpriced for what they are, but there's nothing wrong with a little modernity on occasion.
