If somebody asked me for one Swiss watch
By Dave Kowalski, Chicago ยท
This would be my pick. The Gentleman is 40 mm by 11.5 mm with a blue dial, date, steel bracelet, 100 m. It's sporty enough for work, dressy enough for dinner. That's what you want from a one-watch collection.
The Powermatic 80 inside has a silicon hairspring ("silicium" in Tissot speak), which means it's more resistant to magnetism. That's a big deal for a guy like me who's around motors, transformers, and panels all day. Magnetism is a real problem for mechanical watches, and this thing just doesn't care as much.
80 hours, display back, sapphire. $775 to $850.
The only thing I'd change is the 21 mm lugs, again. But you're probably wearing it on the bracelet anyway.
