Which one fits
Lug to lug matters more than case diameter: if the lugs hang past the edges of your wrist, the watch looks too big. All three are drawn to the same scale, with each model’s marked hours in yellow.
Middle 39
39 mm case, 46.5 mm lug to lug, 11.4 mm thick
Wrists from 6 to 7.5 inches, 152 to 190 mm.
Dog Watch GMT 40
40 mm case, 47.5 mm lug to lug, 12.6 mm thick
Wrists from 6.75 to 8.25 inches, 171 to 210 mm.
First Watch Chrono 41
41 mm case, 48 mm lug to lug, 14.2 mm thick
Wrists from 7 to 8.5 inches. It sits taller than the other two.
Between sizes? Put your wrist measurement in the order notes. We size the bracelet before it ships, and the clasp adjusts another 8 mm in 2 mm steps.
