If your relatively new to watches or replacing a watch strap, it can be difficult to know what size you need for your replacement watch strap.
The easiest way to know is to check your current watch strap and see if there is a number on the reverse side of the watch strap. The most common sizes for Mens watch straps are 20mm and 22mm, then 18mm, 21mm, and 24mm.
If there is no number on the watch strap it is always best to check the size by measuring. As per our picture, measure between the two lugs of the watch. This will tell you what size you need. Don't worry about space for the strap to fit. A 20mm watch strap may be just under 20mm but it has been made to fit a lug to lug measurement of 20mm.
There are some watches that will not accept standard spring bar pins and have either an integrated strap or a custom made watch strap connection.
I hope this information is useful to you. If you require further assistance or you are unsure if your watch takes standard spring bar pins feel free to contact us and we will gladly help.
