The short answer
To give someone a watch without measuring their wrist, measure a watch they already wear instead of measuring their arm. Measure the diameter of the watch case from one edge to the other, and stick to the same size range, give or take a millimeter or two.
If you don't have access to any watches, choose a model with a tool-free adjustable strap—such as a sliding Milanese mesh, an extendable strap, or a leather or fabric strap with a buckle—and aim for a case size of 30 to 36 millimeters for a slender wrist, and 36 to 42 millimeters for a wider wrist. This is the most forgiving range.
If the size doesn't fit, you can exchange the watch. You have 30 days from the date of receipt to change your mind, and we'll cover the cost of returning the item for an exchange using a shipping label we'll send you. This is stated on our Exchanges and Refunds page.
Can you choose a watch size without measuring your wrist?
Yes. The challenge isn't knowing a specific number; it's not being able to ask for it without giving the game away.
What we're looking for isn't really a wrist twist
Wrist circumference is measured in centimeters and is used to adjust the length of a watchband. What really matters, however, is the case diameter and the distance between the lugs. The good news can be summed up in one sentence: a watchband that’s too long can be shortened or replaced, whereas a case that’s too large cannot be adjusted to fit.
If you're buying for yourself, take your measurements
So it's all much simpler, and our guide to choosing the right watch size based on wrist size explains how to measure with a tape measure and what sizes correspond to each measurement. This page focuses solely on the case of a gift—when taking a measurement isn't possible.
What should I measure on a watch she's already wearing?
This is the safest method, and it takes two minutes while the person has their back turned.
The diameter of the case, from one edge to the other
Lay the watch flat and measure the width of the case from one edge to the other, excluding the crown. A school ruler will suffice. If you don’t have one, a coin can serve as a reference: a one-euro coin is 23.25 mm in diameter and a two-euro coin is 25.75 mm, according to dimensions published by the European Central Bank.
The distance between the horns—the number no one looks at
The lugs are the four parts that hold the bracelet in place. Their spacing determines whether the watch fits between the two sides of the wrist or extends beyond them. A 40-millimeter case with short lugs looks better on a slender wrist than a 38-millimeter case with long lugs.
The width of the bracelet—for later
Also note the width of the watchband where it attaches to the case—a measurement in millimeters that is almost always an even number. This information comes in handy when you want to change the band, and our watchbands are organized by this width.
| What you point out | Where it can be read | What is it used for? |
|---|---|---|
| Case diameter | From one end to the other, outside the city limits | The main reference point, to be replicated with an accuracy of one or two millimeters |
| Horn span | From the top of the upper horn to the bottom of the lower horn | This means that the watch will stick out beyond the wrist, regardless of its diameter |
| Strap width | At the entrance to the Horns | Used to purchase a bracelet, not to choose a watch |
How do you estimate the size of a wrist in a photo?
When there's no watch available, photos are the next best thing—and they're better than a hunch.
Find a photo where the hand is resting flat
A good photo is one in which the hand is resting on a table, palm down, with the wrist aligned with the forearm. If the person is already wearing a watch on that wrist, even better—the scale is on the wrist.
Compare it to an object whose size you know
A phone, a mug, a credit card. The object should convey scale, not precision. When in doubt, err on the side of caution.
What a Photo Will Never Tell You
Neither the thickness of the wrist, nor its shape, nor whether the person likes to wear their watch tight. A photo gives a rough idea of size, not an exact measurement, and that's why the watchband matters.
What case size allows for a margin of error?
There is a range within which an error of two millimeters is imperceptible. Rather than copying predefined ranges, we measured our own catalog.
The sizes actually sold, as listed in our catalog
Of the 4,546 listings in our watch section, 266 models are currently available, and 209 of them list their case size. The median case size of these 209 watches is 36 millimeters.
| Case diameter | Number of models available | For which wrist? |
|---|---|---|
| Less than 28 mm | 27 | Very slender wrists, jewelry-style design |
| From 28 to 33 mm | 50 | Slender wrists, a discreet watch hidden under a sleeve |
| From 34 to 37 mm | 43 | The most forgiving area, for almost any wrist size |
| From 38 to 40 mm | 55 | Medium to large wrists—the current standard for men |
| From 41 to 43 mm | 21 | Wide cuffs, bold presence |
| 44 mm and larger | 13 | For wide wrists only—sports and diving |
In the women's section, the median size is 30 millimeters across 93 product listings; in the men's section, it is 40 millimeters across 74 product listings; and for unisex styles, it is 34 millimeters across 28 product listings.
Is a 44 mm watch considered large?
Yes, honestly. Of the 209 watches available for which the size is listed, only 13 are 44 millimeters or larger. That’s an exceptional size—typically found in sports and diving watches. If in doubt, go with 40.
And if you have a small wrist, does that mean you have to give up on beautiful watches?
No. Below, you'll find a 34-millimeter case made of steel with sapphire crystal and an automatic movement. For a slender wrist, look for three things: a case under 36 millimeters, short lugs, and a moderate thickness.
Which bracelet can be adjusted without tools?
This is the most effective feature on this page—the one that turns a major concern into a non-issue. Of the 266 watches available in our catalog, 196 come with a strap that can be adjusted without any tools, and 69 come with a metal link bracelet.
The Milanese mesh—the one that slides
It's the perfect gift. The clasp isn't attached to a specific hole—you can place it anywhere along the chain—so it fits almost any wrist. Our catalog features 21 available styles.
The stretchy bracelet, which doesn't even adjust
Its metal bracelet is mounted on small springs. It stretches to let your hand through, then snaps shut on its own. No need to adjust it, no need to cut it, and no need to explain how it works to the person receiving it.
Leather, fabric, silicone, and resin—all secured with a single hole
They fasten with a prong buckle, like a belt, and extend several centimeters. This is the most common design, found on 172 of the 266 available watches. And a watchmaker can drill an additional hole in just a few minutes.
The steel link bracelet—the one that requires a workbench
It comes in a standard length and can be shortened by removing links with a tool. This isn't a flaw; it's the most durable design. But it's something you'll need to plan for, and it's not something you can do on New Year's Eve morning.
| Bracelet Type | How to Adjust It | Do we need a tool? | For a gift |
|---|---|---|---|
| Milanese link bracelet | The clasp slides along the chain | No | Ideal |
| Stretch bracelet | It stretches and returns to its original shape | No | Ideal |
| Leather, fabric, silicone, resin | Hole-by-hole, barbed loop | No | Very good, over several centimeters |
| Chain-link steel | We remove links | Yes | Plan to spend some time at the workbench |
What watches should you give as gifts when you can't measure them?
Thirteen watches from our selection, each one reopened on its product page before being listed, with prices and availability double-checked and photos reviewed. They are organized by how their straps are adjusted, and the product page serves as the definitive source of information.
Those with a strap that can be adjusted with a single motion
Milanese mesh or an adjustable bracelet—when you're completely unsure.
Those that are adjusted with a loop hole
Leather, fabric, or resin. The range of materials covered by the holes is wide.
Those that require work on the workbench
A sturdy, elegant steel link bracelet—but be sure to have it adjusted to the right length.
To explore further, check out our women's and men's watch sections, our gift selection, our budget guide if it's your budget rather than size that's holding you back, and our guide to choosing the perfect watch as a gift to help you select the right model.
What happens if the size doesn't fit?
That's the question that should come first, because it takes away the fear.
The exchange, in black and white
You have thirty days from the date you receive the item to make up your mind. If it doesn't suit you, you can exchange it or get a refund. For an exchange, we'll cover the return shipping costs and send you a shipping label so you can return the watch to us at no cost. See the "Exchange or Refund" page for instructions.
Have a steel bracelet cut to length
If it's just the bracelet that's too long, there's no need to send the watch back. A watchmaker can remove the links in just a few minutes. The group's workshop can also do this, based on a quote and never without your approval, as explained on our warranty and after-sales service page.
Change the strap instead of the watch
A watchband can be replaced for a fraction of the price of a watch, and in one go, you can change the size, color, and material.
The gift card: when you're completely unsure
If you don't know the size, style, or color, a gift card is an honest solution rather than an admission of failure. It comes in four denominations, is sent by email with a unique code, and is valid for one year. Everything is explained on our gift card page.
Key Takeaways
Measure a watch she's already wearing, not her arm.
The case diameter and the distance between the lugs are more important than the wrist circumference.
If in doubt, go for a slightly smaller size and a bracelet that can be adjusted without tools.
And if the size doesn't fit, we'll exchange it for you and cover the return shipping costs.
Frequently Asked Questions
How do you choose the right size for a watch to give as a gift without measuring the wrist?
Measure a watch that the person is already wearing, rather than measuring their arm. Measure the diameter of the case from edge to edge, excluding the crown, and round to the nearest one or two millimeters. If you don't have a watch on hand, look at a photo where their wrist appears next to an object of known size, then choose a strap that can be adjusted without tools.
What watch size is right for which wrist?
A slim wrist suits a case measuring 30 to 36 millimeters, a medium wrist suits 36 to 40 millimeters, and a large wrist suits 40 to 44 millimeters and above. These ranges overlap, because the desired look matters just as much as the circumference of the arm. The distance between the lugs is just as important as the diameter.
Is a 44 mm watch considered large?
Yes. Of the 209 watches in our catalog for which the case size is listed, only 13 are 44 millimeters or larger, and the median size is 36 millimeters. This is an exceptional size, reserved for wide wrists and sports watches.
How do you choose a watch that fits a small wrist?
Look for a case under 36 millimeters, short lugs, a moderate thickness, and a narrow strap. A small diameter doesn’t mean a cheap watch—you can find 34-millimeter cases made of stainless steel, with sapphire crystal and an automatic movement. The watch should fit between the two sides of your wrist.
Which watch band can be adjusted without tools?
The Milanese mesh, with a clasp that slides along its entire length. The stretchy strap, which stretches and returns to its original shape. Leather, fabric, silicone, and resin—all adjustable hole by hole. A link bracelet, on the other hand, requires a tool. Of the 266 watches available in our catalog, 196 can be adjusted without a tool.
What should you do if the watch you received as a gift is too big or too small?
It can be exchanged. You have 30 days from the date of receipt to change your mind, and for exchanges, we cover the return shipping costs using a label that we provide. The exchange or refund page on our website explains the steps to follow.
Is it better to choose a watch that's a little too big or a little too small?
A little too small. A watch that’s slightly smaller fits comfortably, whereas a case that’s too large wobbles on the wrist and can’t be adjusted to fix it. The strap can be shortened, but the case cannot.
