In order to establish the correct size/fitting for your watch, simply measure the distance (in millimetres) between the case lugs as seen in the illustration above. The determined width will be the size of watch strap you should order.

*In the event that you find the width to be an uneven number, ie. 17, 19 etc. and only in the case that you wish to purchase a leather watch strap - TSS recommends that you order the next size larger. The small degree of compression required to fit a 20mm strap to a 19mm lug width is well within the capability of supple hides. (TSS has not yet had a single return arising from compatibilty/fit issues when supplying the next size up).

** Please note - the above recommendation does not apply if you wish to order a stainless steel watch bracelet. In this instance you will require an exact size match for correct fit.

Sorry - TSS does not stock intermediate (odd) watchstrap sizes at this time.




Deployment clasp compatibility


If you intend to fit your existing deployment clasp instead of using the standard buckle supplied with your strap please note the following buckle end dimension must match that of your existing strap were it attaches to the deployment.

Measure this distance (the standard buckle has been romoved in the illustration seen below).



The degree that watchstraps taper, ie. the difference in width between where the strap attaches to your watch and the width at the buckle end can vary.

As a general guide most (but not all) watchstraps taper by approximately 2mm at the buckle end. eg. a 20mm size will be 18mm at the buckle etc. To ensure correct fitting of your existing deployment clasp you should check that any strap you purchase conforms to the size of your existing deployment clasp.

If in doubt please email ken@thestrapshop.co.uk for advice prior to ordering - thank you.
