How does 18K Custom Atelier engineer its solid Au750, Pt950, and Custom CNC watch cases?

Every monobloc case, bezel, and bracelet link is precision-machined on 5-axis Swiss CNC centers to match the exact authentic original gram mass of the manufacture reference.

Can I inspect the movement regulation and custom dial details before shipping?

Yes. Every timepiece is photographed across 6 workbench angles and accompanied by a pre-shipment 4K video on our Witschi Chronoscope and Mettler-Toledo digital gram balance.

How are bespoke wrist sizing and international logistics handled?

Our watchmakers size the bracelet or strap to your exact wrist circumference (14.0 cm to 22.0 cm), include all spare links, and dispatch via insured priority courier.
