The first question everyone asks about a vintage watch is the diameter, and it’s the least useful measurement on the spec sheet. A 34 mm dress watch with a thin bezel and long lugs can occupy more wrist than a 38 mm cushion case. What your eye actually reads is the dial opening; what your wrist actually feels is the lug-to-lug span and the height.
Vintage watches run smaller than modern ones because they were sized to be worn, not photographed. Under a shirt cuff, over an actual wrist bone, 34 to 37 millimetres is not a compromise. It is the size most of these designs were drawn for. The Polerouter’s proportions collapse at 40 mm; at 34.5 they are perfect.
The measurements that matter
Lug-to-lug, first: a watch that spans past the edges of your wrist will always look borrowed, whatever the diameter says. Then thickness, which decides whether it slides under a cuff. Then the bezel: a slim one makes a 34 mm dial read like a 36. Diameter comes fourth.
Our listings give diameter, but also lug-to-lug where it changes the story. If you’re unsure how a piece will wear, write to us with your wrist size. We measure, we don’t guess.
