Good starting points for first Swiss mechanical are Tissot, Hamilton, Mido, or Certina. They all belong to the same conglomerate (the Swatch Group).

The "gateway drug" these days seems to be Tissot PRX. Their quartz models are about half the price of their mechanical ones.

I just grabbed a Tissot Gentleman 38mm as my first Swiss machine. Same movement but a little smaller, and in my opinion a more handsome case

The Gentleman is a great starter watch, enjoy!
