The single most common reason a watch gets returned is that it is the wrong size for the wrist. Two minutes now saves a return later.
How to measure your wrist
Take a strip of paper about a centimetre wide, wrap it around your wrist just below the bone, mark where it overlaps, then lay it flat against a ruler. That number in centimetres is your wrist circumference.
As a rough guide: under 16 centimetres is a narrow wrist and a case above 40 millimetres will look large on it. Between 16 and 18 is the middle, where most case sizes work. Above 18 and a small case starts to look lost.
The lug-to-lug measurement matters more than the diameter. That is the distance from one strap attachment to the other, and it decides whether the watch overhangs the wrist. A 40 millimetre case with long lugs can overhang a wrist that wears a 42 millimetre case with short ones perfectly well.
Straps
The steel bracelet is sized by removing links, and we include the removed links so you can add them back later. Leather straps come in one length that fits most wrists.
Tell us your measurement
Write to info@acm-swiss.com with your wrist circumference and we will send you the exact case dimensions for each model and tell you honestly which one fits, including if the answer is none of them. A person answers, usually the same day.
