SIZE GUIDE

1. How to measure lug width

Lug width is the inside distance between the two lugs of the watch case, where the strap is attached. It is always given in millimetres.

Remove the current strap, or measure with it fitted if the ends are visible.
Place a ruler or calipers between the inner faces of the lugs, level with the spring bar.
Read the value to the nearest millimetre. Most watches measure 18, 19, 20, 21, 22 or 24 mm.

Not sure? Look up your reference number with the Strap Finder. A strap that is 1 mm too narrow leaves a visible gap; a strap that is too wide will not fit.

18 mm 19 mm 20 mm 21 mm 22 mm 23 mm 24 mm

2. Wrist size: short or long strap

Wrap a soft tape (or a strip of paper) around your wrist where you wear your watch and note the circumference. Then choose the strap length:

Wrist circumference	Strap length	Typical split (long / short side)
14 – 16.5 cm (5.5 – 6.5 in)	Short / Small	approx. 105 / 70 mm
16.5 – 19.5 cm (6.5 – 7.7 in)	Regular / Medium	approx. 115 / 75 mm
19.5 – 22 cm (7.7 – 8.7 in)	Long / Large	approx. 120 / 75 mm

Lengths vary by strap; the exact sizes are shown on each product page. Cut-to-size straps are trimmed to your wrist at home.

3. Integrated straps: counting bracelet links

Integrated straps re-use the folding clasp from your current bracelet. The size is set by how many removable links your bracelet has on each side of the clasp.

Hold the bracelet with the clasp at the bottom.
Count the removable links (those held by a screw or pin) between the clasp and the case, on the 6 o'clock side and the 12 o'clock side.
Write it as “6 o'clock by 12 o'clock”, for example 4 by 6, and pick the size with the same numbers.

Links on your bracelet	Choose
4 by 4	X-Small / Small
4 by 5 or 4 by 6	Small / Medium
5 by 5 or 5 by 6	Medium / Large
6 by 6	Large / X-Large

Jubilee bracelets use different link counts; the matching sizes are listed on each Jubilee product page.

4. Smartwatches

Apple Watch: 38 / 40 / 41 mm and 42 mm (Series 10 and later) share one band size; 42 mm (Series 1–3) / 44 / 45 / 46 / 49 mm share the other.

Made for 20 mm lugs

Straight ends on standard spring bars, 20 mm at the lugs. It fits any watch with that lug width; the models we had in mind are listed under Details.

FKM rubber, the step up from silicone

FKM is a denser rubber than silicone: it shrugs off sweat, sunscreen, salt water and UV, and it does not pick up lint and dust the way silicone does. After a swim or a run, rinse it under the tap and it is dry in minutes.

Watch Tool – for Rolex Strap installation

Swapped in minutes, dispatched in 1–3 business days

The strap fits on standard spring bars, so the swap takes a couple of minutes with a spring-bar tool. If you do not own one, the Lugline spring-bar tool is $13.00, or any watchmaker will do it while you wait.

US shipping is $5.99 and free from $40. Orders are dispatched in 1–3 business days and typically arrive about 7 business days after dispatch. Unworn straps can be returned within 30 days.
