Which strap size is right for you depends mainly on your wrist circumference and the particular strap model.
Our straps cover a wide range of different wrist circumferences. You'll find the exact size range on the product page of the strap you're interested in.
How do I measure my wrist circumference correctly?
The easiest way is to use a flexible tape measure.
- Wrap the tape measure around your wrist at the point where you normally wear your watch.
- The tape measure should sit snugly, but shouldn't cut into your skin.
- Read off the circumference in centimetres.
- Then compare your measurement with the size range given on the strap's product page.
Example:
If your wrist measures 17 cm and the strap you want is suitable for a wrist circumference of 15 to 20 cm, it should generally fit.
What can I do if I don't have a tape measure?
You can also use a strip of paper, a ribbon or a piece of string instead.
Wrap it around your wrist once and mark the point where the two ends meet. You can then measure the length with a ruler.
Should I measure especially snugly or loosely?
Measure your actual wrist circumference as precisely as possible, and don't add a few extra centimetres yourself.
With a classic leather or textile strap, your preferred fit can later be adjusted using the strap holes.
If you like to wear your watch a bit looser, make sure your wrist circumference isn't right at the upper end of the given size range.
My wrist is exactly between two sizes – which one should I choose?
If a strap is offered in several sizes and your wrist circumference falls between two variants, your personal wearing preference also plays a role.
Do you prefer to wear your watch:
- snugly on your wrist, the smaller variant may be more comfortable,
- a bit looser, the larger variant usually offers more room.
However, make sure you still fall within the recommended size range given on the product page.
What does the length of a strap mean?
For two-piece straps, two lengths are often given. These refer to the two strap halves.
However, the plain strap length can't always be directly equated with your wrist circumference, as the size of the watch case also makes up part of the circumference.
For choosing the right size, the recommended wrist circumference given on the product page is therefore the simplest and most reliable guide.
Does the size of the watch also play a role?
Yes.
The same strap can feel a little different on the wrist with two differently sized watches, because the diameter or length of the watch case also covers part of the wrist.
That's why, whenever possible, you should always follow the details given for the specific strap or the intended combination when making your choice.
What size do I need for a metal strap?
Metal straps are adjusted differently to leather or textile straps.
Here, the length is usually adjusted by removing or adding individual strap links. Depending on the model, there may also be a micro-adjustment on the clasp.
The size range given on the product page shows you which wrist circumferences the metal strap is generally suitable for.
If the strap is too long on delivery, it can be shortened accordingly.
Can I shorten a metal strap myself?
This depends on the particular strap and how the strap links are constructed.
If you're not familiar with shortening metal straps, we recommend having the adjustment carried out by a watchmaker or another qualified professional. This helps you avoid scratches or damage to the strap, pins or screws.
What's important for very slim wrists?
If you have a very slim wrist, you should pay particular attention to the smallest wrist circumference given.
With leather and textile straps, what matters is whether the strap can be closed tightly enough. With metal straps, on the other hand, you need to check whether enough links can be removed.
The case size of the watch also affects how well the combination sits on the wrist.
What's important for a larger wrist?
Pay attention to the maximum wrist circumference given for the particular strap.
If your wrist is very close to the upper end of the size range, the strap may generally still fit, but might offer less room for a looser fit.
Can I just measure my current strap?
This can be helpful as an additional point of reference.
If your current watch strap fits well, you can, for example, compare its overall length or the strap hole you use with a new strap.
For a reliable choice, though, we still recommend measuring your wrist circumference directly, as strap constructions and case sizes can vary.
