Made to Order

Each JS Mods timepiece is custom-assembled and made to order. We do not hold large volumes of finished stock.

Please allow an estimated 2–3 week lead time for assembly, inspection, and preparation prior to dispatch.

Bracelet Sizing

Stainless steel bracelets, where applicable, can be resized by removing or adding links to achieve a comfortable fit. With basic tools, minor adjustments can be made at home; however, we recommend having the bracelet adjusted by a professional jeweller or watchmaker to ensure a proper fit and avoid damage.
