Strap Length Guide

Selecting the correct strap length ensures optimal balance, comfort, and a refined presence on the wrist.
Please refer to the measurements below as illustrated.

C — Buckle Side Length

The length of the strap section attached to the buckle, measured from the lug end to the buckle.
This side contributes to stability and overall strap balance on the wrist.

D — Hole Side Length

The length of the strap section with adjustment holes, measured from the lug end to the tip.
This side determines the adjustment range and final wearing position.

Standard Strap Lengths

Strap length is expressed as Long End / Short End (D / C):

S — Small (105 / 65 mm)
Recommended for wrists below 16 cm (6.3 in).
Ideal for a close, tailored fit with minimal excess strap.
M — Medium (115 / 75 mm)
Our standard size, suitable for wrists 16–18 cm (6.3–7.1 in).
Offers balanced proportions and all-day comfort.
L — Large (125 / 85 mm)
Recommended for wrists above 18 cm (7.1 in).
Provides extended adjustment while maintaining stability and elegance.

Custom Strap Length

Beyond standard sizes S / M / L, CERNIR offers custom strap lengths, handcrafted to your exact preferences.

If you require a specific length—whether due to wrist size, watch case dimensions, or personal wearing style—please select Custom Length and provide your desired measurements (Long End / Short End), or contact us for personalized guidance.

Each custom strap is individually made to order, ensuring a precise fit without compromise.

How to Measure Your Wrist

Wrap a flexible measuring tape snugly around your wrist at the position where the watch is worn.
Measure without tightening to ensure accuracy.

Notes

Strap length is measured as two separate pieces, not end-to-end.
Watch case size, lug-to-lug length, and strap thickness may slightly affect perceived fit.
If you are between sizes or uncertain, our team is always available to assist you in selecting the ideal length.
