Thinnest Automatic Watches

Thin watches are the hallmark of refined horology. These automatic and manual-wind watches represent the slimmest mechanical options in our database.

Engineering Thinness

Getting an automatic movement thin requires ingenious engineering. Micro-rotors, peripheral rotors, and ultra-flat mainsprings all contribute. Every tenth of a millimeter matters when the goal is a watch that practically disappears on the wrist.

What to Expect

Under 10 mm: dress-watch territory. 10-12 mm: versatile daily wearer. Over 12 mm: sport/tool watch proportions. The watches below are sorted from thinnest to thickest.
