SÖNER size guide

Watch Size Guide: How to Measure Your Wrist

Find the right SÖNER for your wrist in two minutes. Measure your wrist, see every case size to scale next to a bank card, and print a life-size paper watch to try on at home.

Step 1

Measure your wrist

Wrap a soft measuring tape, or a strip of paper, around your wrist just below the wrist bone, where you wear a watch.
Keep it snug but not tight. With paper, mark where it overlaps and measure the length with a ruler.
Enter the number below and press Find my size.

Step 2

Compare the case sizes

Every SÖNER is rectangular, so two numbers matter: the width across your wrist and the height along your arm. Here are all three case sizes to scale next to a standard bank card, which you probably have in your wallet right now.

Shown to scale. Case width × height in mm.

Tank Royal 24 × 34 mm · 6 mm thin · 18 mm strap A classic dress size in the true Tank tradition: compact, thin and discreet under a shirt cuff. Shop Tank Royal → Nostalgia 28 × 40 mm · 7 mm thin · 20 mm strap A refined, classic case size. The curved case back follows the wrist, so it sits close and slips under a shirt cuff. Shop Nostalgia → Amorous 28 × 40 mm · 10 mm · 20 mm strap The same classic case size with a Swiss automatic movement. The curved case back follows the wrist, so it sits comfortably all day. Shop Amorous → Legacy 35 × 45 mm · 10 mm · 22 mm strap A bolder case with real presence on the wrist, for those who like a watch to be seen. Shop Legacy → Momentum 35 × 45 mm · 10 mm · 22 mm strap The bold case size with a Japanese automatic movement and a clean Art Deco look. Shop Momentum →

Step 3

Try it on at home

Print a life-size paper watch of all three case sizes, cut them out and wrap them around your wrist. It is the easiest way to see what suits you before you order.

Print at 100% (Actual size), not "Fit to page". A 50 mm check bar on the sheet tells you the scale is right.

Good to know

Height matters more than width

On a rectangular watch the height, measured along your arm, decides how the watch sits. Look at the flat top of your wrist: the case should sit within it, without reaching over the edges.

Thickness and shirt cuffs

A thin case slides under a shirt cuff. Tank Royal is 6 mm and Nostalgia is 7 mm, so both disappear under a cuff. Amorous, Legacy and Momentum are 10 mm.

Choosing your strap size

Nostalgia and Amorous straps come in two sizes, for wrists under or over 17.5 cm (6.89 in). Legacy and Momentum straps come in two sizes, for wrists under or over 20 cm (7.87 in). Pick the one that matches your measurement on the product page.
